中高渗透层压裂工艺初探
DISCUSS ON FRACTURE TECHNOLOGY IN HIGHER AND MODERATE PERMEABLENESS LAYER
-
摘要: 探讨了中高渗透层(渗透率为50×10-3~200×10-3μm2)压裂配套工艺。在蒙古国19区压裂作业中采取了阶段式压裂液滤失控制技术、油气层保护技术、蜡球分压技术、全三维压裂优化设计软件模拟技术等配套技术,5口油井取得了很好的压裂效果。Abstract: The matching technology of fracture in higher and moderate permeableness formation was discussed. In Mongolia, the control technology of fracture fluid filtrate loss was used by phase. At the same time, oil and gas formation protect technology, separate layer fracturing with wax ball technology and others were also used matching. After five wells using, the better effect of fracture was obtained.
