| 摘 要： | 新疆阜康白杨河矿区煤层气开发利用先导性示范工程是新疆第一个煤层气开发利用示范工程。新疆阜康白杨河矿区地形复杂，多为山地丘陵，地层具有“高倾角、多煤层、大厚度”的地质特点，示范工程部署的井型大部分为丛式井，因此定向钻井技术得到广泛应用。本文主要从示范工程现有井排采情况，分析了井身质量对管杆偏磨的影响，并从钻具组合和定向工艺优化等几个方面对本地区定向钻井技术进行了研究，同时对该技术在本区块应用过程中出现的一些问题进行了探讨，为今后该区块定向钻井技术的推广应用奠定了技术基础。

| Abstract: | Xinjiang Baiyanghe mining area is the first case of CBM development and utilization demonstration project in Fukang of Xinjiang, mountains and hills there make complicated topography with geological characteristics of high strata dip, multiple and large thickness of coal seams. Therefore, cluster wells are mainly planned in this area and the directional drilling technology is widely applied. This paper mainly analyzes the influence of well bore quality on the eccentric abrasion of tube and rod based on the drainage and production situation of existing wells in the demonstration project, and studies the directional drilling technology in this area in bottom-hole assembly and directional drilling technique optimization. Some problems in the application of directional drilling technology are discussed, which can provide technical basis for the future application of this technology in this area. |
