摘要
水力压裂是低渗透油田开发的主要技术手段。油层岩石地应力的大小和方位决定了压裂裂缝的形态。通过室内三轴实验、测井解释和压裂施工数据3种方式来获得黄陵地区长6储层的地应力数据．分析认为该储层不易造长缝，应该以复杂裂缝系统为主要的改造思路，后面开展微地震监测进行了验证。
Hydraulic fracturing is the main technical means for low permeability oilfield development. The size and orientation of crustal stress of reservoir rock determine the induced fracture＇ s morphology. The crustal stress data of Chang6 reservoirs in Huangling region are obtained by three ways of indoor triaxial tests, logging data interpretation and fracturing construction data. It is believed by analysis that ti＇ s not easy to create long fractures in the reservoirs. The main stimulation ideas should take a complex fracture system as the dominated. The later conducted micro-seismic monitoring verified its correctness.
