风城油田作业区是一个以超稠油油藏开发为主的油田,目前采用SAGD技术开采油田已经投产,产出可观,收到了良好的效益,越来越多的SAGD井组需要开发,SAGD井组对靶窗和轨迹高要求,轨迹控制过程中存在的误差影响会很大程度影响到轨迹的精度控制,同时大大降低了油藏采收效率,因此有必要有效解决控制SAGD轨迹问题,如何精度控制轨迹是提高油藏采收率的关键。 The Fengcheng Oilfield operating area is an oilfield mainly developed for super-heavy oil reservoirs. At present, the oilfield exploited by SAGD technology has been put into operation with considerable output and good returns. More and more SAGD well groups need to be developed and SAGD Well group requires high target window and trajectory, the error influence in trajectory control will greatly affect the accuracy of trajectory control, and greatly reduce the oil recovery efficiency, so it is necessary to effectively solve the control SAGD trajectory problem, how to Accuracy control trajectory is the key to improve oil recovery.
