Research and application on wire cable soft drifting technology

The wire cable soft drifting technique is a newly drifting operation mode that far different from the traditional one, which provides a novel technical means for underground drifting operation in oilfield. Work-over rig XJ-150 was improved and the tensile strength tests were performed on the matching equipment to form a set of new drifting operation process using wire cable instead of tube. Field application results showed that this technique could do the work to replace the tube, and this operation method solves the problems of multiple trips, high intensity of labor, long construction period, and High operating costs with a prosperous application.
