宁晋石盐田Y9-Y10井组对接连通钻修井技术

Intersection drilling and workover of the well pair Y9-Y10in Ningjin Rock Salt Field

摘要:

随着水平对接连通技术不断地发展与完善，各个领域都开始引用，盐井采卤引用该技术更是取得了良好的效果。宁晋石盐田为组建采卤生产井组，决定对已完井多年的Y10井先进行修井，然后新建水平定向井Y9井对接连通。从井身结构、钻具组合、钻井液配方、钻进参数和钻进过程等多方面对两井组的对接连通进行了系统的总结，为该区以后卤水的开采提供了地质依据与实践经验。

Abstract:

With the continuous development and improvement of horizontal well intersection drilling technology, it has been used in various fields, especially in salt brine mining wells. In the context of workover and drilling of the well pair of Well Y10 and Well Y9 in Ningjin Rock-salt Field, this paper systematically summarizes the well structure, drilling tool assembly, drilling fluid formulation, drilling parameters and drilling process, which provides valuable geological basis and practical experience for brine exploitation in this area.
