绳索定向造斜及取心技术应用

Application of Wire-line Directional Drilling and Coring Technology

摘要:

绳索取心技术因其钻进效率高而广泛应用，但其无法实施定向作业。本项目可在采用绳索取心的同时，不需要采用井底螺杆钻具进行定向勘探，该技术是近几年才发展起来的高新技术。目前在世界范围内，仅有少数几个国家掌握该技术，其中以挪威和美国取得世界领先地位。简要介绍了绳索定向造斜和取心技术的原理及技术参数，并介绍了云南华泽矿区的施工应用实例。

Abstract:

Wire-line drilling is widely used due to its high drilling efficiency; however, it cannot carry out directional drilling. The wire-line directional drilling and coring technology can take cores and drill directionally without using down-hole motors. The technology is a high-tech emerging in recent years, only a few countries have mastered it, and Norway and America lead the position in the world. This paper describes the wire-line directional drilling and coring principle and technical specifications with field application in Huaze mine of Yunnan.
