砾岩油藏侧钻水平井井位筛选──以克拉玛依百口泉油田为例

Preferred Selection of Sidetrack Horizontal Well Location in the Conglomerate Reservoir-an example from Baikouquan oilfield.

侧钻水平井技术是一项新型的油田开发技术，但是，侧钻水平井能否获得好的效益，关键是井位筛选。作者根据侧钻水平井的特点及目前的工艺水平，结合砾岩油藏地质特征、剩余油分布状况及开发现状，提出了侧钻水平并试验区、目标区、目的层以及侧钻基础井位的优选原则。通过在百口泉油田实际应用表明：该方法实用有效，筛选出的井位实施后获得了很好的开发效果，为侧钻水平井技术在老区的应用提供了一套有效的井位优选方法。

The technology of sidetrack horizontal drilling is a new type of oilfield development technology. But the key that can make a good benefit or not is dependent on preferred well locations. Based on its special properties and re-cent technological levels together within the geologic features, remaining oil distribution and present production status of conglomerate oilfields, the authors proposed preferred principles for the pilot test area, target area or zone and base well locations of sidetrack horizontal drilling. Application of them to Baikouquan oilfield showed that following implementa-tion of preferred selected well locations, outstanding production effectiveness has been achieved, providing a set of prac-tical and effective techniques of preferred selection of sidetrack horizontal well locations in aging oilfield.
