Description
В ОСНОВНОМ авт. св. № 108840 описан способ уменьшени содержани воды и газа в добываемой нефти путем закачки в зкой жидкост.1 в призабойную зону пласта, с целью снижени фазовой проницаемости дл воды или газа. Известный способ борьбы с обводненностью скважин не обеспечивает длительную эксплуатацию их, т. е. закаченна в водоносную часть пласта нефть вымываетс . Обычный цементаж водонасыщенной части пласта сокращает приток нефти К скважине, а последн быстро обводн етс .BASIC Auth. St. No. 108840 describes a method for reducing the content of water and gas in produced oil by injecting a viscous liquid.1 into the bottomhole formation zone in order to reduce the phase permeability to water or gas. The known method of combating the watering of wells does not ensure their long-term operation, i.e. the oil pumped into the aquifer of the reservoir is leached. Conventional cementing of the water-saturated part of the reservoir reduces the flow of oil to the well, and the latter is quickly irrigated.
Предлагаемый способ уменьшени содержани воды и газа в добываемой нефти вл етс дальнейшим совершенствованием изобретени ио авт. св. К° 108840. Он состоит в том, что после закачки в зко жидкости в призабойную зону пласта производ т последующую цементную заливку ее. После затвердени цемента производ т повторное вскрытие верхней части пласта.The proposed method for reducing the water and gas content in the produced oil is a further improvement of the invention. St. To ° 108840. It consists in the fact that after injection into the fluid in the bottomhole formation zone, the subsequent cement pouring is performed. After the cement hardens, the upper part of the formation is re-opened.
Следовательно, быстрое обводнение скважины предупреждаетс закачкой в зкой жидкости в пласт, а цементаж обеспечи вает длительный срок нормальной эксплуатации и увеличивает межремонтный период работы скважины.Consequently, the rapid watering of the well is prevented by the injection of a viscous fluid into the formation, and cementing ensures a long period of normal operation and increases the turnaround time of the well.
Предмет изобретени Subject invention
Способ у меньшени содержани воды и газа в добываемой нефти по авт. св. JVs 108840, отл ич ающи йс тем, что, с целью предотвращени в процессе эксплуатации пр мого вытеснени закаченной в пласт жидкости, после закачки последней производ т цементную заливку с последующим вскрытием верхней (нефт ной) части пласта одним из известных способов.The method has less water and gas content in the extracted oil according to the author. St. JVs 108840, differing from the fact that, in order to prevent the direct injection of the fluid injected into the formation during the operation, after injection of the latter, cement pouring is performed followed by opening the upper (oil) part of the formation using one of the known methods.
