摘要
套管开窗侧钻作为老油田提高采收率的技术,因其明显的优势,近年来得到了迅速发展和广泛应用。八面河油田应用侧钻井技术取得了较好的开发效果和经济效益。在进行井位筛选和优化设计方案时应遵循的原则是:将井斜、裸眼段长、水平位移分别控制在35度、400米、200米之内,尽量减少变方位变井斜的工作量保证井眼平滑,提高侧钻井固井质量和增油效果。
Cased well sidetracking technology is rapidly developed and widely applied in recent years for its obvious advantages of improving oil recovery of old oil fields. Good production results and economic benefits are achieved by using the technique in Barnianhe Oilfield. When selecting well location and optimizing design plan, the authors advo- cate sticking to the following principles including restricting hole deviation, barefoot interval and horizontal displacemere in the scope of 35 degrees, 400 meters and 200 meters respectively, trying to decrease the work of changing direction and hole deviation to ensure smooth borehole and increasing the quality of sidetracking and cementing wells and the results of oil increase.
