Opis:: Na przełomie lat 1980-1981, podczas wiercenia otworu poszukiwawczego "Daszewo-1" wystąpiła otwarta erupcja węglowodorów. Intensywny wypływ ropy naftowej na powierzchnię wraz z towarzyszącym jej gazem ziemnym trwał 33 dni i w tym czasie przedostało się do środowiska od kilkunastu do kilkudziesięciu tysięcy ton ropy naftowej. W wyniku zaistniałej erupcji stwierdzono zanieczyszczenie gleb ropą naftową wokół otworu "Daszewo-1" na obszarze 27 ha. Dla ukazania aktualnego stanu środowiska gruntowo-wodnego, po upływie około 30 lat od zaistniałej awarii pobrano do badań laboratoryjnych próbki gleb, gruntów i wód podziemnych w celu oznaczenia w nich koncentracji węglowodorów. Otrzymane wyniki porównano z aktualnie obowiązującymi standardami jakości gleb i gruntów oraz wód podziemnych dla terenów upraw rolniczych i nie stwierdzono przekroczeń dopuszczalnych koncentracji węglowodorów.
At the turn of 1980-1981, when exploration well "Daszewo-1" was drilled, an intense eruption of oil and natural gas occurred. It lasted 33 days and during that time dozen to tens thousands tones of oil were released to the environment. The soils around well "Daszewo-1" were polluted in the area of 27 ha. After 30 years the soil, ground and groundwater samples were taken for laboratory analyses, during which hydrocarbon concentrations were established. The obtained results were compared with the present qualitative standards of soil, ground and groundwater in the agricultural areas. They do not reveal any higher values than the standards for admissible hydrocarbon concentrations.

Opis:: Drilling process of deep borehole consists of different drilling operations. Each of them can cause numerous different drilling problems especially when a borehole is performed. While drilling the most dangerous problems can occur once the drilling fluids (oil, gas or water) spontaneously flow out from the drilled formations into the borehole and then to the surface. It can also happen that the pressures in the borehole are not balanced and an influx of fluid into the borehole (a kick) will occur. If no action is taken to stop a kick once it begins, then the fluids will be pushed out of the borehole and will be flowing uncontrollably to surface (blow-out). Blow-out is prevented by closing off the well at the surface with special kind of valves (Blow-out Preventers - BOPs). When pressure control over the well is lost, swift action must be taken to avert the severe consequences. These consequences may include: — endangering of human life, — loss of rig and equipment, — negative influence on the environment, — additional costs of bringing the well under control again, — loss of reservoir production. In the case of kick or blow-out will occur in the practical use are different procedures and methods to control a borehole. These procedures and methods depend on the actual drilling operation scenario. One of them can be a tripping operation when the drill string is pulled out or run back again. In this case the drill string is open either after a break-out or before making up the drill pipes and drill collars. There is a variety of tools that can be used to prevent the formation of fluids rising up inside the drill pipes. One of this tool is a safety valve (rod preventers - BOP) to prevent the blow-out of the drill string. This manuał safety valve should be kept on the rig floor at all times. It needs to be a fuli opening ball-type valve so there is no restriction to flow. This valve is installed onto the top of the drill string if a kick occurs during a trip. However, this solution is quite inconvenient and difficult because involves special heavy tools, e.g. a crane. Drilling process of deep borehole consists of different drilling operations.

This paper presents a new solution making use of special control equipment for the blowing open drill string. This equipment is based on a hydraulic press (named "Drill Pipę Rescue Press I") which has been developed by HBZS, MND S.A. Hodonin and VSB-Technical University of Ostrava, supported by Faculty of Drilling, Oil and Gas AGH-UST Kraków.
