文档介绍：旋转磁场测距导向系统在稠油/ 超稠油开发中的应用摘要:在稠油/超稠油开发中, SAGD 双水平井对采收率的贡献最大,但是仅 SAGD 依靠双水平井井型具有一定的限制,而双水平井加连通井的方案为浅层稠油/超稠油(特别是浅层稠油/超稠油)开发提供了新的技术途径。旋转磁场测距导向系统是在 20世纪 90 年代发展起来的邻井距离探测新技术,可以直接探测钻头到目标井的距离和方位,可用于 SAGD 双水平井和连通井的井眼轨迹控制, 而且旋转磁场测距导向系统在双水平井加连通井方案的施工中具有明显的技术优势。因此,旋转磁场测距导向系统在稠油/超稠油(特别是浅层稠油/超稠油)开发中具有广阔的应用前景。关键词: 旋转磁场测距导向系统; SAGD ;双水平井;连通井;浅层 RMRS Application in Heavy Oil / Ultra-heavy Oil Reservoirs Developments S UN Dongkui, GAO Deli , DIAO Binbin ( Key Laboratory for Petroleum Engineering of the Ministry of Education, China University of Petroleum, Beijing 102249 , China ) Abstract: In heavy oil/ ultra-heavy oil reservoirs developments, twin parallel horizontal SAGD wells play the most important role in enhancing oil recovery, but the twin parallel horizontal SAGD wells technology also has some disadvantages. However, bination of the twin parallel horizontal SAGD wells technology and the connected well technology offered the new way for developing heavy oil/ ultra-heavy oil reservoirs (especially shallow heavy oil/ ultra-heavy oil reservoirs). RMRS, which isa new technology for detecting adjacent well distance and developed in 1990s, can be utilized to detect the distance and direction from drilling bit to target well and can be used in the well path control of twin parallel horizontal wells and connected wells. Moreover, RMRS enjoys obvious advantages in the project bining twin parallel h
