摘　　要：东辛油田有各种油藏五大类十余种 ,经过三十余年的开发 ,采油难度与日俱增 .本文较为系统地论述了不同类型油藏的地质特点 ,尤其是剩余油的分布特点 .并根据不同油藏的剩余油分布特点 ,应用水平井技术、细分层开采技术、完善井网技术、不稳定注水等四大开发技术分类进行治理 ,使油藏的各项开发指标都有明显的好转 ,有效地改善了油藏开发效果 ,取得了明显的社会经济效益 .Dongxin oil field is one of the main oil fields in Shengli oilfield, which is also a most complex oil field in terms of geologic condition. There are more than ten types of oil pool in five big oil pool classes in the oil field. Different types of oil fields have different geologic properties and different technics of exploitation are required. Having exploitated for more than thirty years, difficulties of oil extraction are growing day by day. In this paper, the geologic characteristic of different oil pool types, especially the distributing characteristic of remaining oil are discussed. According to the distributing characteristic of remaining oil in different oil pools, four kinds of exploitation technology including the technology of applying horizontal well, exploitation technology of subdivision delamination, technology of perfect well network and unsteady affusion, are put up for afthering classification. Exploitation targets of oil pool have been obviously looked up, exploitation effects of oil pool have been availably improved, and significant socioeconomic benefit has been obtained.
