Abstract

Sposób szczelinowania hydraulicznego skał polegający na tym, że w otworze wiertniczym, na odcinku przebiegającym w warstwie skał zbiornikowych umieszcza się przynajmniej jeden ładunek materiału wybuchowego (5) z zapalnikiem i izoluje się ten odcinek od reszty otworu, a następnie wprowadza się do wyizolowanego odcinka ciecz szczelinującą i zwiększa się ciśnienie cieczy szczelinującej, po czym detonuje się ładunek materiału wybuchowego (5) i dalej tłoczy się ciecz szczelinującą oraz podsadza hydraulicznie materiałem podpierającym szczeliny, charakteryzujący się tym, że detonację ładunku materiału wybuchowego (5) inicjuje się w trakcie tłoczenia cieczy szczelinującej, po osiągnięciu przez ciecz szczelinującą wartości ciśnienia szczelinowania skał zbiornikowych, lecz nie później niż w chwili, gdy ciśnienie cieczy szczelinującej w otworze spadnie w wyniku wytworzenia szczelin do wartości 30% ciśnienia szczelinowania.The method of hydraulic fracturing of rocks consists in the fact that in the borehole, on the section running in the reservoir rock layer, at least one explosive charge (5) with the igniter is placed and the section is isolated from the rest of the hole, and then the fracturing liquid is introduced into the isolated section and the fracturing liquid pressure increases, then the explosive charge (5) is detonated and the fracturing liquid is pressed and hydraulically propped with fracture support material, characterized in that the detonation of the explosive charge (5) is initiated when the fracturing liquid is pumped, when the fracturing fluid reaches the fracturing pressure of reservoir rocks, but no later than when the fracturing fluid pressure in the bore drops as a result of the formation of fractures to 30% of the fracturing pressure.
