FIELD: drilling and operation of horizontal oil wells. SUBSTANCE: curved wellbore is made in the form of elbow and lowered to depth ensuring normal lowering of intake of pumping device to under level of fluid pumped out of well. Capacity of pumping device is such that level of oil in well does not exceed the depth of horizontal wellbore or depth of producing formation occurrence. EFFECT: higher production rate of well drilled in deposits with low formation pressure. 1 dwg |
