摘要
阐述了地应力作用下储层裂缝和微裂缝的形成机理,应用XMACⅡ测井取得的最大水平主应力方位数据分析了最大水平主应力作用方向对油层注水开发的影响。裂缝的走向方位或最大水平地应力方位是注水受效明显方位;在注水井压裂效果理想情况下,其周围沿最大水平主应力方位排布的采油井将会得到较好的增液、增油效果,而在压裂效果不理想的情况下,其周围沿各方位油井都很难见到效果。
The reservoir fracture and microfracture formation mechanism under ground stress has been stated in this paper. Through the application of XMACⅡlogging technique, the effect of the maximum principal stress orientation in horizontal direction on water flood development in oil reservoirs has been analyzed.The fracture orientation and the maximum ground stress are both affected by water flood.When the fracturing effect of water injection well is ideal,oil production along the maximum principle stress orientation could reach the effect of liquid and oil increment,while if not, good results are difficult to be achieved.
