长井段砂泥岩薄层提高压裂效果工艺技术研究与应用

Fracturing in long interval sand-mud thin reservoirs

针对DG油田南部油区孔一段油组的储层特点,采用分层压裂工艺技术和支撑剂粒径组合技术,提高油层的改造程度和加砂规模;优选了易返排的防水锁低伤害压裂液体系,降低压裂液对储层的伤害,经现场广泛应用取得了明显的增产效果。

Layered fracturing and proppant size combination are used to modify the reservoir and sanding scale in Kong-Iformation,DG oilfield.The fracturing fluid that is water-lock preventive and low-damage is selected to eliminate the damage offracturing fluid to reservoir,which has received good results in practices.
