摘　　要：辽河油田开采已经进入中后期,油层出砂严重,地层砂埋住油层后,严重影响油井的正常生产,常规的冲砂方式很难在低压漏失井内建立循环,无法将地层砂冲出地面。研究了双级同心整体冲砂管柱,建立了内循环液体冲砂通道,配合水力喷射泵采用自吸力的原理,实现低压漏失井的冲砂施工任务,促进了油田的修井作业施工。Exploitation oil is already on mid-evening in Liaohe oil field,the oil layer sand flow is very severity,when the sand would be buried the oil layer,that graveness infection oil well produce,but the routine sand cut mode build the circle is very hard in low press leak lose well.So we develop the both concentric whole sand cut pipe that will build up inside circle sand cut channel,and concert water power eject pump self-suction elements which come true sand cut construct mission in low press lose well.The technics promote the well workover task in oil field.
