水力压裂受储层的地层压力状态所控制 ,是生产井的主要增产措施。地层压力状态不仅控制着水力压裂的方向 ,更多的是控制着所产生的水力压裂的几何形态。地层应力随储层地质史的演变而变化 ,留下诸如天然裂缝和各向异性渗透率等印记。然而 ,在截然不同的几个月甚至几小时的时间 Hydraulic fracturing is controlled by the formation pressure status of the reservoir and is the major stimulation measure for the production wells. The formation pressure state not only controls the direction of hydraulic fracturing, but also controls the geometry of the hydraulic fracturing. Stratigraphic stress changes with the evolution of the reservoir’s geological history, leaving impressions such as natural fractures and anisotropic permeability. However, in quite different months or even hours
