随着合水油田水平井大面积开发,多层系、立体开发的水平井组技术已日渐趋势,我队在庄233井区施工的4口水平井外加3口定向井井组,主要开发长6和长7油层,本文从表层钻进技术,优化钻具组合,细化轨迹控制思路,优化钻井参数等方面剖析,摸索总结出一套完善、成熟的钻井技术集成模式,对区块后续水平井施工具有推进指导意义。
With the large-scale development of horizontal wells in the Heshui oilfield, horizontal well group technology with multi-level and three-dimensional development has been gradually increasing. The 4 horizontal wells and 3 directional well groups that our team constructed in Zhuang 233 well area mainly develop 6 And Chang 7 oil layer, this paper analyzes and summarizes a set of complete and mature drilling technology integration models from the aspects of surface drilling technology, optimization of drilling tools, refinement of trajectory control and optimization of drilling parameters. Construction has the significance of promoting guidance.
