Abstract
Способ повышения дебита нефтяных и газовых скважин, включающий проведение в каждой скважине геолого-технических мероприятий, обеспечивающих запланированное повышение дебита, отличающийся тем, что вводят в одновременную эксплуатацию все продуктивные пласты в каждой существующей однопластовой скважине и в ее возможном углублении, для чего скважину при необходимости добуривают, разбуривают боковыми стволами, цементируют затрубное пространство в зоне пластов, выполняют вторичное вскрытие всех пластов, осваивают скважину геофизическим сервисом, для чего устанавливают геофизические приборы в зоне каждого вскрытого пласта, плавно понижают уровень жидкости в скважине, например свабированием или его аналогами, затем извлекают приборы и по их показаниям определяют величины забойных давлений и других параметров флюида в скважине, при которых пласты включаются в работу, по этим данным определяют пласты, подверженные пластовым перетокам, выполняют геолого-технические мероприятия, обеспечивающие устранение выявленных пластовых перетоков, затем снова устанавливают геофизические приборы в зоне каждого пласта и спускают в скважину на расчетную глубину добычной насос, например струйный насос, нейтральный к действию выделяющихся из рабочих пластов газов, приводящих к гидроударам и к разносу электроцентробежных насосов, в ремонтный период добычного насоса анализируют показания геофизических приборов и при выявлении пластовых перетоков из-за выработки пластов выполняют геолого-технические мероприятия по устранению пластовых перетоков, снова опускают добычной насос и продолжают добычу с указанных повторенA method of increasing the production rate of oil and gas wells, including the implementation of geological and technical measures in each well, ensuring the planned increase in production rate, characterized in that all productive formations in each existing single-layer well and in its possible deepening are put into simultaneous operation, for which the well is necessary drill, drill with sidetracks, cement the annulus in the formation zone, perform a secondary opening of all the layers, drill the well with geophysical service, for which geophysical instruments are installed in the area of each opened formation, smoothly lower the liquid level in the well, for example by swabbing or its analogues, then the instruments are removed and their values determine the bottomhole pressure and other parameters of the fluid in the well, at which the formations are included in the work , according to these data, formations that are subject to formation flows are determined, geological and technical measures are carried out to ensure the elimination of identified formation flows, then geophysics are established again instruments in the zone of each formation and are lowered into the well to the calculated depth of the production pump, for example, a jet pump that is neutral to the gases released from the working layers, resulting in water hammer and separation of electric centrifugal pumps, during the repair period of the production pump, the readings of geophysical instruments are analyzed and, if reservoir flows due to the development of reservoirs carry out geological and technical measures to eliminate reservoir flows, again lower the production pump and continue production from these repeated
