| 摘 要： | L井是中原油田的一口预探井,设计井深4 650.00 m。在井深4 235.60 m处取心钻进过程中,取心钻头的底齿圈断裂落井,采用多种方法打捞处理均未获成功,最后决定填井侧钻。在井深大,温度高、地层可钻性差、工具面不易控制的情况下,采用螺杆钻具和有线随钻技术侧钻成功。文中详细介绍了该井深部侧钻工艺的施工过程。

Sidetracking Technologies Used in Deep L Well |
| |
| Abstract: | L well, with a designed well depth of 4650. 00m, is a wildcat in Zhongyuan oilfield. A drilling accident occurred at the depth of 4235. 60m and fishing operation failed, thus the well was sidetracked. Screw drill and wireline logging while drilling technologies were used and sidetracking operation was successfully accomplished. This paper details the operation process of deep sidetracking in this well. |
