钻井利器的故事之“慧磁”高精度定向中靶导向系统

The story of a drilling weapon—SmartMag drilling target-hitting guide system

摘要:

磁导向对接井技术的出现，大大提升了对接连通率，目前广泛应用在天然碱等可溶性矿产的开采中。随着该技术的不断发展，作为地下“穿针引线”导航利器的优秀代表——“慧磁”高精度定向中靶导向系统，以其出色的测量精度、稳定性及可靠性已在国内外对接井中取得数百次的好成绩。本文从科普的角度介绍了井下对接导航的必要性、“慧磁”系统的组成及技术原理、“慧磁”系统发展历程及近年来取得的成果，以此提高大家对“慧磁”系统的认识，达到相互交流、相互促进的目的，最终推动以“慧磁”系统为代表的主动磁测系统的技术持续发展和应用领域的不断拓展。

Abstract:

The emergence of magnetic guided butted well technology has greatly improved the connectivity of docking. Now the technology is widely used in the mining of natural alkali and other minerals. With the continuous development of this technology， as an excellent representative of the underground “thread the needle” navigation tool—SmartMag drilling target-hitting guide system， with its excellent measurement accuracy， stability and reliability， has made hundreds of good achievements in the water solution mining butted wells at home and abroad.From the perspective of science popularization， this paper introduces the necessity of downhole docking navigation， the composition and principle of SmartMag system， the development process of SmartMag system and the achievements made in recent years， so as to improve everyone’s understanding of the SmartMag system， achieve the purpose of mutual exchange and mutual promotion， and finally promote the continuous development of the technology and the continuous expansion of the application field of the active magnetic measurement system represented by SmartMag system.
