海上油气田由于投资大、钻井少、取资料困难,相对陆上油气田而言其剩余油研究则困难得多。针对C2油藏高含水、高采出程度、剩余油高度分散的现实问题,以高分辨地震、钻井和测井等资料为基础,综合应用开发地质、生产测井和油藏工程等技术,对C2油藏的剩余油分布进行了研究。综合多种方法的研究成果,认为构造北部剩余油最为富集,并得到了挖潜井的证实,最终提高了油藏的产量和采出程度,为同类海上油藏剩余油分布研究提供借鉴。

Due to the large investment, less drilling, and difficulty to obtain data, the research of remaining oil in offshore is more difficult than land oil field. Aiming at the problem that C2 reservoir has the characteristics of high water cut, high recovery, and the highly dispersed of remaining oil. At the basis of seismic, drilling and logging data, the distribution of C2 remaining oil was forecast-ed by the application of the technology of geological, logging and reservoir engineering. By the research results of various methods, the remaining oil is most enriched in the north of C2 structure that was approved by adjusting well. And production and recovery of C2 reservoir was improved by adjusting well. The method is worthy of reference by the same kind reservoir in offshore.
