摘　　要：杏河东北部为多油层复合岩性油藏．主要发育层位有长4＋5、长6层．随着开发时间的推移，储层的非均质性影响和层间压力恢复不均的矛盾逐渐凸显为了改善多油层开发的效果，衣文开展了分层注水、深部调剖、注水政策调整、分层采油等一系列多油层开发的试验．为后期研究和提高多油层开采水平提供了技术思路。The northeast Xinghe Oilfield is a muhi-layer complex lithologic reservoir. The main development of horizons includes Chang4＋5, and Chang6 reservoirs. With the development time, passing, the conflict between impact of reservoir heterogeneily and uneyen buildup of reservoir pressures becomes inereasingly prominent. In order to improve the effect of multi-reservoir development, this paper carried out a series of muhi-reservoir development tests, such as separated-zone water injection, deep profile-control, waterflooding policy adjustmenls, and separated-zone oil recovery.It provides technical ideas for the post researches and improvement of the multi- reservoir exploitation level.
