大庆朝阳沟油田浅层水平井钻井技术

Drilling Technology for Shallow Horizontal Well in Chaoyanggou Oilfield of Daqing

摘要:

介绍朝阳沟油田98区浅层水平井的井身结构特点、地层岩性特点以及该区水平井轨迹控制的难点。针对这些特点以及不同地层的造斜率，制定有效轨迹控制方案，选取合理的造斜工具及钻具组合，实施合理的钻井参数及技术措施，完成浅层水平井的施工。

Abstract:

The paper introduced Chaoyanggou oilfield about the well structure characteristics, formation lithology and difficulties in horizontal well trajectory control. Based on these characteristics and deflection rates in different stratums, effective trajectory control scheme was designed; reasonable deflecting tool and drilling tool assembly were selected with reasonable drilling parameters and technology for shallow horizontal well construction.
