Description
Применение оиисансюго способа позвол ет избегать осложнений при бурении скважины в толще пород, где встречаютс одновременно и зоны -поглощени , и значительное лластозое давление.The use of the intrusive method allows to avoid complications during the drilling of a well in the strata of rocks, where both absorption zones and significant llastose pressure are encountered.
Ф о р м у л а изобретени F o rmu l invention
Способ создани местной циркул ции бурового раствора с использованием энергии нагнетаемого в скважи1ну сжатого газа, отличающийс тем, что, с целью создааи в скважине давле-ни , раэного пластовому , и обеспечени его посто нства, лер«одичвс .кн мен ют на|П,равление иагнетаии газа в бурильных трубах и эатрубном пространстве , лоддержива давление истечени его из циркул ционной системы на задац .ной величине.The method of creating a local circulation of drilling fluid using the energy of compressed gas injected into the well, characterized in that, in order to create pressure in the well, which is normal to the reservoir, and to ensure its constancy, Lehr wilds switch to | P, control of gas injection in the drill pipe and the pipe space, keeping the pressure from flowing out of the circulation system at the target value.
