大民屯断块丛式井钻井技术

Technology of Cluster Drilling at Damingtun Faulted Block

我国首次用丛式井钻井技术开发大民屯油田,获得了显著的经济效益。一个陆地平台最多钻成17口定向井。丛式井是以整体开发断块油田复式油气藏的总体规划而设计的。它的实施具有钻井为勘探开发服务的战略意义。

In our country, the cluster drilling technology has been applied for the first time to develop Damingtun oil field and obtained remarkable cconomic benefit. On a land drilling platform can be completed 17 directional wells at most. Cluster drilling is designed for an overall plan in developing multiple reservoirs of faulted block oil field. Application of this technulugy has a strategic significance that drilling serves exploration and development.
