延平1水平连通井组轨迹精确控制技术

Precise trajectory control technology in horizontal connected well group of Yanping-1

延平1水平连通井组具有水平段长、可开发的有效煤层薄、远端连通等技术难点。在认真分析技术难点的基础上,详细阐述了延平1井组的技术措施和轨迹精确控制工艺技术以及精确连通工艺技术,实现了全井段轨迹平滑、轨迹控制精确、远端连通一次成功。为以后在该地区施工同类型井起到了良好的借鉴作用。

The horizontal connected well group of Yanping-1 has many technical difficulties with long horizontal sections, thin available coal seams, remote connectivity and so on. Based on the analysis of technical difficulties, this paper made detailed de- scription about technical measures, accurate trajectory control technology and precise connectivity technology of Yanping-1 well group, which achieved the goal of smooth whole section trajectory, precise trajectory control and successful ont-time remote connec- tivity, providing valuable references for the operation of the same types of wells in this area in the future.
