摘　　要：对低孔低渗油层考虑到地层地应力的方向和河道砂体的走向,提出了采用定方位射孔;考虑到普通压裂液对地层造成一定伤害,提出了采用低伤害压裂液压裂;考虑到压裂液滞留时间长,造成地层二次污染,影响改造效果,提出了采用JS-2型不动管柱压裂排液监测一体化技术。本文通过采用综合配套技术(定方位射孔、低伤害压裂液压裂、JS-2型不动管柱压裂排液监测一体化技术)在低孔低渗透扶杨油层两口井(古74、双51井)试油压裂改造的现场应用,达到了增产增效的作用。The orientation perforation tech is suggested for low porosity and percolation oil layer considering stress direction and riverway sand trend and, fracture with low damage fractured fluid is developed because of some harm to formation is made for common fractured fluid. JS-2 model integrative tech of fracture by unmoving stem to unload fluid and monitor is provided with a view to long time of fracture fluid to resort to cause the second time of pollution and influence reform effect. The paper introduces that by using comprehensive matching tech (orientation perforation, fracture with low damage fractured fluid, JS-2 model integrative tech of fracture by unmoving stem to unload fluid) in 2 wells of low porosity and percolation reservoir of Fuyang Oilfield, effect of increasing productivity and result has been reached.
