摘　　要：水平井技术在油田开发中被广泛的应用,为了开发浅层的稠油油藏,增大井眼与油藏的接触面积,提高单井的产量。在苏丹S-C/F区块进行了稠油油藏水平井技术的应用,将IGD地质导向技术引入到水平井钻井施工中,油藏钻遇率100%。本文以该区块水平井为例,将三维地质建模与传统地质导向技术相结合,充分利用LWD实时数据,取得高油层钻遇的良好效果。地质导向技术在该油田的成功实施,为水平井技术及地质导向技术在稠油油田的应用提供借鉴,并就现今现有的技术存在的问题提出研究建议。Horizontal drilling technology is widely used in oilfield development in order to develop shallow heavy oil reservoir and increase the contact area between wellbore and reservoir,so that the production of single well is increased.Horizontal well technology for heavy oil reservoir was applied in S-C/F block of Sudan.IGD geological steering technology was introduced into horizontal well drilling,and the oil reservoir drilling rate was 100%.Taking horizontal wells in this area as an example,3D geological modeling was combined with traditional geological steering technology,good drilling results in high oil reservoirs was achieved by making full use of LWD real-time data.The successful implementation of geological steering technology in this oilfield provides reference for the application of horizontal drilling technology and geological steering technology in heavy oil fields.At last,some suggestions on the research of existing technical problems were put forward.
