摘　　要：桥口油田受油藏平面及纵向上非均质严重的制约 ,油田Ⅰ类层过早进入高含水期 ,低渗层水驱动用难度大 ,开发水平变差。针对油田非均质严重 ,Ⅱ、Ⅲ类储层水驱动用程度偏低的开发现状 ,在前期综合研究及室内压裂试验的基础上 ,应用了适合油藏特点的新型复合压裂工艺技术 ,实施后效果较好。As the layer class I reachs high water-cut stage,Qiaokou oilfield appears some difficults on water-flooding in low-permeability layers limited by a serious horizontal & vertical heterogeneity,the developing situation became worse.Regard the serious heterogeneity in layers class Ⅱ,Ⅲ,the composite fracturing technology suitable for the reservoir are applied.The results show that postfracture response is good.At the same time,the good result provides some successful experiences for fracturing in the whole Qiaokou Oilfield & improving waterflooding efficiency of low-porosity & low-permeability layers.
