摘　　要：渤海海域的渤中25-1油田沙二段为异常高压低渗油藏,油田在实际开发过程中由于受储层异常高温高压低渗特点影响,开发效果不理想。文章针对低渗油藏开发生产过程中存在的问题,通过沙二段低渗油藏合理注采井距、注水时机、注水先导试验、配套工艺技术等多方面研究,制定了针对异常高压低渗油藏切实可行的治理对策,实现了沙河街油藏注水开发,达到改善低渗油藏开发效果。BZ25-1 oil field is an abnormal high pressure and low permeability reservoir in Bohai Sea. Influenced by the characteristics of reservoir, the development and production of oilfield is ineffective. This paper researches on reasonable injector producer distance, timing of injection, leading injection experimental practice and matching process in Shahejie two section to solve the existing issues in practical development of low permeability reservoir. Approach reasonable and practical measures in development of abnormal high temperature and pressure, low permeability reservoir. Achieve water injection development in Shahejie reservoir and improve the development effect.
