三维双靶点圆弧内切线中靶控制技术

Control technology of three-dimensional double-target-point arc internal tangent hitting-targets

江汉油田已步入勘探开发后期,寻找剩余油,挖潜增效已成为当前的首要任务。王4斜—3—12B井三维双靶井的设计与施工,改变了过去多靶点连线方位与井口在同一铅垂面上的二维多目标井的钻井模式。采用三维双靶点圆弧内切线中靶控制技术,打双靶变方位多目标井,为今后开发断块油藏和不同油层间的剩余油提供了成功的钻井经验。

Jiianghan Oilfield has entered the exploration and development later period, and the current principal task is in search of remaining oil, digging potential ＆ increasing benefit. The design and the construction of Wang4 Xie- 3 -- 12B three- dimensional double- target, has changed two- dimensional multi- target well drilling mode in the past, which is multi-target point link azimuth and wellhead are at the same vertical surface. To apply the control technology of three-dimensional double-target--point arc internal tangent hitting-targets to drill tow-target variable-orientation azimuth multi-target well, has provided successful drilling experience for developing remaining oil in fault block oil reservoir and different oil reservoir.
