锦29块低渗透性油藏二次开发可行性研究

Study on secondary development feasibility of Jin 29 block low permeability reservoir

锦29块杜家台油层为一低孔低渗岩性-构造油气藏,采用天然能量开发一次采收率仅为4.72%。为挖掘该块的生产潜力,从油藏特征、开发效果评价以及储层的微观特征、渗流特点等多个方面运用数模和室内实验研究的方法,进行注水二次开发的可行性研究,提出了适应油藏自身特点的全面注水开发方案和相应的实施要求。

Dujiatai oil formation in Jin 29 block is a low porosity and low permeability lithologic reservoir. Recovery rate was only 4.72% by using natural energy. In order to explore the production potential of study area, number module and lab experimental research methods are applied on many aspects as reservoir characteristics, development effect evaluation, reservoir microscopic features, and seepage characteristics. The feasibility study on water injection secondary development is carried out, the comprehensive water injection plan and corresponding implementation requirements is proposed, which is suitable for reservoir characteristics.
