摘要: 辽河油田具有丰富的稠油资源,是我国最大的稠油生产基地。近些年来,辽河油田采用水平井技术开采稠油,取得了较好的效果。为了进一步提高稠油采收程度,辽河油田进行了杜84-兴H238 鱼骨型水平井的井身结构、钻具组合和钻井液等施工方案的设计与优化,并进行了顺利实施。最终效果评价表明,采用鱼骨型水平井进行稠油开采比用单纯水平井具有更明显的优势,能够更有效地提高稠油油藏的油井产量和稠油采收率。

Abstract: Liaohe oil field is rich in heavy oil resources, it is the largest heavy oil production base in china. In recent years, Liaohe oilfield produced its heavy oil with horizontal well technology, and achieved good results. In order to improve heavy oil recovery ratio, the well structure, drilling string, drilling fluid and operation programs in Du84-XingH238 fishbone horizontal well was designed and optimized. The final effect evaluation result indicates that the fishbone horizontal well is more effective than normal horizontal well for exploitation of heavy oil and EOR.

Key words: Liaohe oilfield, heavy oil, fishbone horizontal well, recovery ratio, optimized design, site operation
