На начальном этапе цикла обработки повышает давление на забое скважины. Уровень давления при этом ограничивают величиной давления гидроразрыва пласта. Давление на забое поддерживают в течение времени, необходимого для установления пьезометрической кривой, что контролируют по стабилизации расхода. После репрессии быстро снижают давление на забое ниже пластового для чего открывают затруб и включают струйный насос. При снижении давления на забое ниже пластового производят виброволновое воздействие гидродинамическим генератором с вибросмешением нефтяного коллектора больше 0,1 среднего диаметра поровых каналов и виброускорением большим чем 0,1 ускорения свободного падения. По мере очистки призабойной зоны передача пульсаций давления от генератора вглубь пласта "как по жидкости" увеличится и хотя величина депрессии постепенно будет снижаться, но одновременно увеличивается и радиус охваченной депрессией зоны и радиус обработки. Способ рекомендуется использовать при освоении и очистке скважин, в особенности скважин эксплуатируемых в осложненных условиях разработки, а также наклонных и наклонно-горизонтальных скважин. При этом способ характеризуется высокой эффективностью очистки скважин, эксплуатируемых в осложненных условиях разработки нефтяных месторождений, а также возможностью эффективной обработки наклонных и наклонно-горизонтальных скважин. 5 з. п. ф-лы, 2 ил.At the initial stage of the treatment cycle increases the pressure at the bottom of the well. The pressure level is limited by the value of the fracture pressure. The pressure at the bottom is maintained for the time required to establish a piezometric curve, which is controlled to stabilize the flow. After repression, pressure on the bottomhole below the reservoir is quickly reduced, for which the annulus is opened and the jet pump is turned on. By reducing the pressure at the bottomhole below the reservoir, a vibration-wave effect is produced by a hydrodynamic generator with the vibration mixing of an oil reservoir larger than 0.1 of the average diameter of the pore channels and a vibration acceleration greater than 0.1 of the acceleration of free fall. As the bottom-hole zone is cleaned, the transfer of pressure pulsations from the generator into the reservoir “as in fluid” will increase and although the magnitude of the depression will gradually decrease, the radius of the zone covered by the depression and the radius of the treatment will also increase. The method is recommended to be used during the development and cleaning of wells, in particular wells operated in complicated development conditions, as well as inclined and inclined-horizontal wells. In this case, the method is characterized by high cleaning efficiency of wells operated in the complicated conditions of the development of oil fields, as well as the ability to effectively treat inclined and inclined horizontal wells. 5 h. item f-ly, 2 ill.
