Opis:
W artykule przedstawiono metodykę pomiarów, sposoby prezentacji danych oraz wyniki interpretacji profilowań zarejestrowanych sondą Production Log (PL) w ramach testu produkcyjnego w otworach hydrogeologicznych. Dla zobrazowania opisanej metodyki pomiarów produkcyjnych i ich interpretacji przedstawiono wyniki analizy pomiarów z otworu M-1 służącego jako studnia dostarczająca wodę termalną, otworu K-3 przeznaczonego do zrzutu zasolonych wód kopalnianych oraz otworu geotermalnego SS-1.
Measurement methodic, data presentation modes and results of interpretation of profiling made with the use of a Production Log (PL) within a production test in hydrogeologic wells are presented in the paper. The described measuring methodic and interpretation are presented on the example of data from the geothermal well M-1, well K-3 for discharging mine's waste brine, and geothermal well SS-1.

Opis:
Most of the useful aquifers in Poland occur in the Quaternary and Tertiary horizons, which are deposited at a depth of tens to hundreds of meters. Owing to the need of providing large quantities of water for municipal and industrial purposes, the aquifers are more and more frequently opened with large diameter wells of various designs. Such wells are mostly drilled with the rotary method with reverse mud circulation with the use of various bits. The Quaternary and Tertiary strata abound in loose and weakly consolidated rocks therefore cutter bits are predominantly used. They allow for high rates of drilling and shorter time of drilling of the well. This significantly influences the negative influence of drilling mud on the near screen zone of the aquifer and better hydraulic properties of the well. Drillability tests were performed with cutter bits of 0.86 and 0.67 m diameter for providing high rates of drilling of large diameter intake wells in loose and weakly consolidated rocks. The research was made for measurement sections 0.5 to 1.0 m long, and each of them was drilled at con- stant rotational velocity and axial weight on bit. Prior to the drillability tests the limitation of weight on bit and rotational velocity of bit imposed by the technical characteristic of Prakla B50 rig, strength of the string and butter bit were established. Various regression models were analyzed for the sake of finding a dependence between drilling rate and axial weight on bit and rotational velocity of bit for particular macroscopically homogeneous layers. The best results were obtained for the exponent model illustrating the influence of axial weight on bit and rotational velocity of bit on the drilling rate, which has been proved by the calculated regression coefficients and statistical parameters.

Opis:
The open-pit extraction of lignite in the Bełchatów Lignite Mine can be conducted after prior deep dewatering of the rock mass, realized with large-diameter dewatering wells distributed in the form of outer and inner barriers. This type of dewatering system allows for safe extraction of lignite, however residual waters in the overburden may locally create hazard. These are rain waters infiltrating into the rock mass, and which, due to the complicated geological structure of the deposit and disturbed system of layers, were not intaken by wells belonging to the primary dewatering system. They are removed through the existing and newly drilled exploration wells, which are converted into drainage wells. Such wells are used for removing waters suspended in permeable overburden and gravitationally moved to the lower absorbing layers, from where they are directed to the primary dewatering system wells and then to the surface water courses. The applied enhancement of the dewatering system used in the lignite deposit significantly improves the safety of mining works conducted in this place. Technical and technological aspects of drilling dewatering wells in Bełchatów Lignite Mine are discussed in this paper and followed by the evaluation of efficiency of dewatering of the overburden.
