增效射孔是指通过一次性射孔,使目的层能达到完善或超完善状态,即通过一次性射孔就能够完全消除油层在钻井、完井和射孔过程中受到的油层伤害。三相流高能复合射孔压裂技术是在两相流复合射孔技术的基础上发展起来的,该工艺是把聚能弹射孔(89弹)和可控固体推进剂与加砂压裂结合为一体,射孔、压裂和加砂一体完成,使压裂井的完善程度和完善率达到最高的增效射孔技术。从实施效果对比看,三相流射孔技术对不同物性和埋藏深度不同的油气层都有较广泛的适应性和推广应用价值,是油气层解堵改造又一新的工艺技术。
Synergistic perforating refers to the one-time perforation, so that the target layer can achieve perfect or super perfect state, that is, through a one-time perforation can completely eliminate the oil layer in the drilling, completion and perforation process suffered reservoir damage. The three-phase flow high energy composite perforation fracturing technology was developed on the basis of the two-phase composite perforation technique which combines the shaped charge hole (89 shells) and the controlled solid propellant with sand fracturing As one, perforation, fracturing and sand together to complete, improve the perfection and completion rate of fracturing wells to achieve the highest efficiency perforation technology. From the comparison of implementation results, the three-phase flow perforation technology has wider adaptability and popularization and application value to different hydrocarbon reservoirs with different physical properties and burial depths, and is another new process technology for reservoir blockage reform.
