磁定位测量技术在定向对接钻井施工的应用探析

摘要

For directional butted well construction, the last and the most important step is the docking target. With the application rang expanding from salt well, glauber’s salt well to natural alkali well , geothermal well and CBM well, the target area is getting smaller and smaller, which poses a severe challenge to the traditional target measuring technology. How to solve the problem of low target rate fundamentally? Magnetic positioning measurement technology is a new technology method which makes the target rate reaching 100%, and it is a revolutionary innovation of docking well target technology. Combing with the application examples in several mine, this paper analyzes the principal, characteristics ,advantage and the application prospect of this technology.%对于定向对接井施工而言，最后也是最关键的一个环节就是对接中靶。随着定向对接井的应用从盐井、芒硝井向天然碱井、地热井及煤层气井的日益拓展，其靶区面积越来越小，对传统的中靶测量技术提出了严峻的挑战。如何从根本上解决中靶率较低的问题呢？磁定位测量技术以一种全新的技术方法使对接中靶率达到100%，是对接井中靶技术的一次革命性的创新。本文结合这种技术在几个矿区的应用实例情况，详细探析了这种技术的原理、特点、优势，并分析了其广阔应用前景。
