自煤层气水平对接井领域引入美国Vector公司生产的RMRS旋转磁测距系统以来,我国煤层气和水溶开采领域的定向对接井的施工技术取得了重大突破.然而,大多数应用仍局限于传统的U形井组,属于由一个垂直井和一个水平井组成的井组.而华晋焦煤柳林煤层气项目DS井组是由2个水平井组成的煤层气井组,采用国产“慧磁”钻井中靶引导系统使2井实现“点对点”对接.重点介绍了“点对点”精确中靶作业施工技术方法.

@@@@Since the Rotary magnetic ranging system (RMRS) of America Vector Co.is introduced in CBM horizontal but-ted wells field, major breakthrough was made in the construction technology of directional butted wells both in CBM and so-lution mining industries in China.However, most application is still limited in U-shaped well group composed of a vertical well and a horizontal well.In a project of Huajin coking coal Co., DS well group is a coal-bed methane well group com-posed of 2 horizontal wells, by the target guidance system“Huici” which is made in China,“point to point” is realized. The paper introduced the technical methods of accurate“point to point” target construction.
