SAGD水平井钻井技术

SAGD HORIZONTAL DRILLING TECHNOLOGY

SAGD技术是开发超稠油油藏的一项前沿技术,在国外的超稠油开采中已经得到广泛应用。九十年代末,国内辽河油田在中深层超稠油的开采中开展了SAGD的先导试验,取得了很好的试验效果,形成了相关配套技术。2008年,为提高稠油开采的综合经济效益,拥有丰富稠油资源的新疆油田也已开始着手SAGD技术的试验应用与效果评价工作。本文结合新疆油田SAGD先导试验区块具体油藏特开采特征与SAGD技术在国内外的发展应用等情况,介绍了SAGD水平井钻井技术及其特殊配套的磁性定位导向仪器(MGT与RMRS),以供参考和借鉴。

The SAGD,a heavy oil production technique,has been extensively used in the production of the super heavy oil reservoir at overseas.At the end of 1990s,Liaohe oil field at home firstlly conducted the pilot tests of the SAGD technology in the recovery of the medium and deep super heavy oil reservoir and got good results and formed the related techniques.In 2008,Xinjiang oil field with rich heavy oil resources also began the experimental application and evaluation on the SAGD technique,to improve the comprehensive economical effectiveness of the heavy oil recovery.Based on the reservoir characteristics of the SAGD pilot test area in Xinjiang oil field and the development and application of the SAGD technology at home and abroad,this paper introduces SAGD horizontal drilling technology and the special and necessary magnetic positioning and steering device(MGT/RMRS) presently used in the SAGD parallel horizontal well drilling.
