【摘要】 欢北杜家台低渗透油层的突出特征是构造复杂、断块多,储层物性差,非均质性强,虽然不断进行加密调整,但注水效果很差,采收率仍然很低。因此,要提高低渗油藏采收率,必须要在精细油藏描述、注入水水质优化研究的基础上提出改善开发效果的对策,应用多学科、多技术相结合进行油藏的开发。通过对注入水水质精细处理,达到分级注水,应用膜处理技术,实现注入水质达到A1级标准,应用污水深度处理系统,实现注入水质达到B1级标准。应用高压增注技术,提高注水井注入能力,达到提高原油采收率的最终目标。更多还原

【Abstract】 The outstanding character of Huanbei Dujiatai low permeability oil layer is construction complicated, multi-break mass, formation property badly, heterogeneity strongly. Although we carry on to enlarge density tune continuously, the effect of water injection is bad, the recovery efficiency is still low. Consequently, if we need EOR, we must research based on fine reservoir description, water injecting quality purify, propose counterplan of improving develop effect. We apply many academicses many techniques to oil reservoir development.By the fine handling to the water injection, we can carry out water injection graduatly. We apply film handling technology, make water quality A1 class. We apply sewage handling deeply, make water quality B1 class. We apply high pressure raise water injection technology, enhance injecting ability in water-injecting well. we can hit an object of EOR.更多还原
