Abstract: 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.
