Opis:
The corrosion protection effect of the new S-1 reagent in media with the pH values of 2.0, 4.0, 6.0, as well as carbon dioxide and hydrogen sulfide added separately and combined to the mentioned media, was first tested under laboratory conditions. The protective effect of reagent S-1 was weak in the corrosion medium without hydrogen sulfide and carbon dioxide. However, as the acidity of the medium and the concentration of the reagent increases, the corrosion protection efficiency of the inhibitor also increases. The highest effect is observed at pH = 2.0 and reagent concentration of 30 mg/l. The corrosion protection effect of the reagent reaches 97% under these conditions. In the media with pH = 4.0 and pH = 6.0 without carbon dioxide and hydrogen sulfide, the protective effect of the inhibitor at the optimal concentration of 30 mg/l is 66% and 64%, respectively. In the medium with added carbon dioxide, the protective effect of inhibitor S-1 decreases at pH = 2.0 and, on the contrary, increases at the values of pH = 4.0 and pH = 6.0. Also, as the pressure of carbon dioxide in the medium increases, the protective effect of inhibitor S-1 increases. When hydrogen sulfide is added to the medium, it causes an increase in the corrosion rate and the protection efficiency of inhibitor S-1. However, in the medium without inhibitor, the increase of hydrogen sulfide concentration only up to CH2S = 400 mg/l is accompanied by an increase in the corrosion rate at all values of pH. The addition of 1000 mg/l of hydrogen sulfide to the corrosion medium leads to the decrease in the corrosion rate in the medium without inhibitors and a slight decrease in the protective effect at the concentration of the inhibitor Cinh = 10 mg/l. As the concentration of inhibitor S-1 increases in the medium with the addition of carbon dioxide and hydrogen, its corrosion protection effect also increases. In the range of Cinh = 10–30 mg/l, when PCO2 = 0.5 atm and CH2S = 200 mg/l, the protective effect is estimated at 38–99%, and when CH2S = 1000 mg/l, it is estimated at 17–79%. At PCO2 = 1.0 atm, the value of protective effect is 22–95% and 14–76%, and finally at PCO2 = 2.0 atm, the value of the corrosion protection effect of inhibitor S-1 is estimated at 44–92% and 15–75%, respectively. The coexistence of carbon dioxide and hydrogen sulfide in an aggressive medium leads to an increase in the protective effect of inhibitor S-1 compared to the medium containing only carbon dioxide, and reduces it in comparison to the medium with hydrogen sulfide. An increase in carbon dioxide pressure in the presence of hydrogen sulfide causes a decrease in the protective effect of inhibitor S-1. The protective effect of inhibitor S-1 is lower in the medium with hydrogen sulfide concentration of 1000 mg/l compared to a concentration of 200 mg/l. This case is also observed in the carbon dioxide free medium.
Działanie antykorozyjne nowego odczynnika S-1 w agresywnych mediach o pH 2,0; 4,0; 6,0, a także dwutlenku węgla i siarkowodoru dodawanych osobno lub łącznie do tych mediów, zostało najpierw zbadane w warunkach laboratoryjnych. Działanie ochronne odczynnika S-1 było słabe w środowisku korozyjnym bez siarkowodoru i dwutlenku węgla. Jednak wraz ze wzrostem kwasowości medium i stężenia odczynnika wzrasta również skuteczność inhibitora w ochronie przed korozją. Najlepsze działanie antykorozyjne odnotowano przy wartości pH = 2,0 i stężeniu odczynnika 30 mg/l. Skuteczność ochronna odczynnika wynosi wówczas 97%. W medium o pH = 4,0 i pH = 6,0 bez dwutlenku węgla i siarkowodoru skuteczność ochronna inhibitora przy optymalnym stężeniu 30 mg/l wynosi odpowiednio 66 i 64%. W medium z dodatkiem dwutlenku węgla działanie ochronne inhibitora S-1 maleje przy wartości pH = 2,0 i odwrotnie wzrasta przy wartościach pH = 4,0 i pH = 6,0. Ponadto, wraz ze wzrostem ciśnienia dwutlenku węgla w środowisku wzrasta skuteczność ochronna inhibitora S-1. Dodanie siarkowodoru do medium powoduje wzrost tempa korozji i skuteczności ochronnej inhibitora S-1. Jednak w medium bez inhibitora wzrostowi stężenia siarkowodoru nawet do tak niskiej wartości jak CH2S = 400 mg/l towarzyszy wzrost tempa korozji przy wszystkich wartościach pH. Dodanie 1000 mg/l siarkowodoru do medium korozyjnego prowadzi do zmniejszenia tempa korozji w medium bez inhibitorów i nieznacznego zmniejszenia działania ochronnego przy stężeniu inhibitora Cinh = 10 mg/l. Wraz ze wzrostem stężenia inhibitora S-1 w medium z dodatkiem dwutlenku węgla i siarkowodoru, zwiększa się również jego działanie antykorozyjne. W zakresie Cinh = 10–30 mg/l, gdy PCO2 = 0,5 atm i CH2S = 200 mg/l, skuteczność ochronną szacuje się na 38–99%, natomiast przy CH2S = 1000 mg/l na 17–79%. Dla PCO2 = 1,0 atm skuteczność ochronna wynosi od 22–95% do 14–76%, a przy PCO2 = 2,0 atm skuteczność antykorozyjną inhibitora S-1 szacuje się odpowiednio na 44–92% i 15–75%. Jednoczesne występowanie dwutlenku węgla i siarkowodoru w agresywnym medium zwiększa skuteczność ochronną inhibitora S-1 w stosunku do medium zawierającego tylko dwutlenek węgla i zmniejsza ją w porównaniu do medium z siarkowodorem. Wzrost ciśnienia dwutlenku węgla w obecności siarkowodoru powoduje zmniejszenie skuteczności ochronnej inhibitora S-1. Ulega ona także zmniejszeniu w środowisku o stężeniu siarkowodoru 1000 mg/l w porównaniu do stężenia 200 mg/l. Ten przypadek obserwuje się również w środowisku bez dodatku dwutlenku węgla.

Opis:
Purpose: The purposes of the article are to determine the hydraulic efficiency of two gas gathering pipelines of the Yuliivskyi oil and gas condensate production facility (OGCPF) and develop a set of measures to increase it; to experimentally determine the efficiency of using foams to increase the hydraulic characteristics of the gas gathering pipelines in the Yuliivskyi OGCPF; to develop a set of measures that will help to improve the hydraulic characteristics of gas gathering pipelines. Design/methodology/approach: The research methodology consists in determining the hydraulic efficiency of gas gathering pipelines before and after cleaning their inner cavity with foams with different expansion ratios and comparing the obtained values, which allows to objectively assess the efficiency of this cleaning method. The studies were performed within the framework of research and development work by the specialists of the Ukrainian Scientific Research Institute of Natural Gases. Findings: The pilot testing was carried out to determine the efficiency of cleaning the inner cavity of gas gathering pipelines with foams with different expansion ratios. It showed positive results. It was determined that cleaning the inner cavity of gas gathering pipelines with foams with the expansion ratio from 80 to 90 led to an increase in the hydraulic efficiency coefficient by 10.5%, and with foams with the expansion ratio from 50 to 60 - by 5.7%. The measures taken to clean the inner cavity of gas gathering pipelines from liquid contaminations have proven their efficiency and can be recommended for other fields. Research limitations/implications: The obtained results show that it is reasonable to conduct the experimental studies on the efficiency of cleaning the inner cavity of gas gathering pipelines with the foams with higher expansion ratios. To achieve the maximum quality of cleaning the gas gathering pipelines, it is necessary to develop a new method that will combine the use of foam and gel piston.Practical implications: The performed experimental studies help to take a more reasonable approach to cleaning the inner cavity of gas gathering pipelines with foams and to predict in advance the effect of the foam expansion ratio on the hydraulic efficiency of gas gathering pipelines. Originality/value: The experimental studies on the effect of foam expansion ratios on the hydraulic efficiency of gas gathering pipelines are original.

Opis:
Purpose: Determination of regularities of joint action of mechanical stresses, formation water and hydrate formation on corrosion of material of flow pipelines. Design/methodology/approach: According to the analysis of reservoir water of the investigated deposits, it was found that the main corrosive component is soluble chlorides. Proposed for corrosion and corrosion-mechanical tests of 6 model environments. An estimation of the influence of stress concentration, depending on the defects of the inner wall of the pipe, was carried out, and the nominal local stresses in the pipeline was carried. Findings: The basic regularities of influence of stress and hydration formation on corrosion and localization of corrosion processes and on the kinetics of deformation of samples are described. For samples made of steel 20 and 17GS, an increase in the velocity of general and local corrosion for samples sustained in the gas hydrate was observed compared to the control results obtained, the coefficient of influence of the gas hydrate on corrosion was calculated. Research limitations/implications: The obtained results are valid for thermobaric operating conditions of well flow lines. Practical implications: The data obtained in the work on the patterns of corrosion processes and the impact of hydrate formation on them will allow to identify potentially dangerous areas of flow lines and prevent emergencies. Originality/value: Based on the analysis of the geometric dimensions of the defects, the effective stress concentration coefficients are calculated, and it is shown that the stresses in the vicinity of corrosion defects in normal operating modes range from 164 to 545 MPa.

Purpose: The purposes of this article are to study the effective ways of increasing the hydraulic efficiency of gas gathering pipelines of the Yuliivskyi oil and gas condensate production facility (OGCPF); to calculate the operation efficiency of gas gathering pipelines of the Yuliivskyi OGCPF and develop a set of measures to monitor their condition and improve their hydraulic characteristics; to investigate the technology of cleaning the inner cavity of flowlines of gas-condensate wells with foam, to perform the feasibility study on the prospects of its application in practice. Design/methodology/approach: The technology of cleaning the inner cavity of flowlines of gas-condensate wells with foam was investigated to objectively evaluate its application and determine the effectiveness of this measure. The research was carried out within the framework of research and development work by the specialists of the Ukrainian Scientific Research Institute of Natural Gases. Findings: The results of production studies showed that due to cleaning the flowlines of gas-condensate wells (No.85 and No.60) from the accumulation of liquid, the coefficients of their hydraulic efficiency increased by 12% and 7%, respectively. Measures taken to clean the inner cavity of the flowlines from liquid have proven their efficiency and can be recommended for other flowlines of wells at other production fields. Research limitations/implications: Based on the characteristics of gas gathering pipelines, it is reasonable to conduct experimental studies on the use of the proposed technology of cleaning the inner cavity with foam in the case of increasing its multiplicity. Practical implications: Using the wells of the Yuliivske oil and gas condensate field as case studies, the operating parameters were measured and the pressure losses along the length of the flowlines were calculated. According to the results of calculations at two wells (No.85 and No.60), a significant excess of the actual value of the flow friction characteristic over the theoretical value was established. To reduce excessive pressure losses due to the presence of liquid and improve the hydraulic characteristics of the wells, their inner cavities were cleaned using foam with the expansion ratio from 40 to 100. Originality/value: It is important to note that the advantages of foam piston include: ease of use, no occurrence of hydraulic shocks and preventing stuck during movement in the gas pipeline, application in both straight and inclined sections, no wear of the elements of the cleaning equipment, a rather efficient cleaning of gas pipelines.

Based on a three-year field experiment under controlled condition in Ji’nan, China, the effects of peanut growth on the variation in the abundance and community structure of ammonia oxidizing bacteria (AOB) and archaea (AOA) before and after peanut growth were investigated through quantitative PCR and cluster analysis of terminal-restriction fragment length polymorphism. Our results show that the community composition of AOA and AOB was greatly affected by the peanut growth leading to the decreased abundance of AOA and increased abundance of AOB. Furthermore, AOA and AOB community structures varied before and after peanut growth. Phylogenetic analysis indicated that all AOA and AOB community sequences were clustered into the uncultured group. Altogether, the results suggested that the abundance of AOA and AOB in soil and their community compositions can be greatly affected by the peanut growth.

Purpose: of this paper presents the experimental results of a study of strength and flexural behaviour of non-autoclaved foam-concrete beams reinforced with bamboo Design/methodology/approach: Six experimental samples of reinforced lightweight foamed concrete beams with hardened density D800 and D1200 with the same bamboo reinforcement were tested on lateral bending. Findings: A low level of anchoring of bamboo reinforcement in foam-concrete beams can provide their premature destruction. Research limitations/implications: Next experiments should be provided for improving the anchoring of bamboo reinforcement such as the bad adhesion between the bamboo and foam-concrete caused premature destruction of experimental samples. Practical implications: Replacement of steel reinforcement on the bamboo one in foamconcrete structures can be economical benefit. Originality/value: Increasing of experimental base leads to developing and creating new building standards in the nearest future.
