摘要： 苏丹1/2/4区油田已进入高含水期。在对1/2/4区高含水期水平井适用性研究的基础上,总结了水平井实施后的效果及经验。认为高含水油藏用水平井开采成功的关键是对剩余油的分布要认识清楚,而稠油底水油藏和正韵律储集层顶部差油层利用水平井开发效果明显。开发过程中应合理设计水平井段在油藏中的位置和水平段的长度,并加强水平井的找水、控水措施的研究与实施。这些经验对高含水油田水平井应用与推广具有一定的借鉴作用。

Abstract: The oil fields in block 1/2/4 in Sudan have entered into a high water cut period. This paper reviews the effectiveness and experiences from horizontal drilling process on the basis of the applicability research of horizontal well technology in block 1/2/4. It suggests that the key of adopting horizontal well to development of the high water cut reservoir is in clear recognition of its remaining oil distribution. For the heavy oil and bottom water reservoir and the top poor oil layer of positive rhythm reservoir are more suitable for recovery by horizontal drilling process. During the development process, the position and length of horizontal well interval in the reservoirs should be designed reasonably, at the same time, the research of the water monitoring and controlling treatment should be strengthened. These practical experiences will be as a reference to the horizontal well application in high water cut oil field.

Key words: Sudan, reservoir engineering, horizontal well technology, application performance
