渤海边际油田D油田存在储层连通性和底水等储量风险，为解决工程设施建造规模和储量风险之间的矛盾，探井需具备后期转化为开发井生产的工程条件。在前期研究阶段，将勘探和开发统筹考虑，部署2口探井测试评估储量风险，进行试采平台设备改造并应用井口回接等技术实现了探井转化为开发井的可能，优化隔水管数量、简化井口保护架等措施最大程度地降低了工程投资。前期各专业的有效融合成功实现了海上边际油田勘探开发的一体化，使投资做到有的放矢，该研究对于类似油田开发有指导和借鉴意义。

The marginal oilfield D in the Bohai Sea is faced with the reserve risks of reservoir connectivity and bottom water. And in order to solve the contradiction between the construction scale of engineering facility and the reserve risk, exploration wells shall satisfy the engineering conditions of converting into development wells in the late stage. In the stage of early research, exploration and development are considered overall, two exploration wells are deployed to test and evaluate the reserve risks, and the possibility of converting exploration wells into development wells is realized by modifying the test platform equipment and applying wellhead tieback and other technologies. And the engineering investment is reduced as much as possible by taking some measures, e.g. optimizing the number of risers and simplifying the wellhead protection frame. Based on the effective integration of different professions in the early stage, the exploration-development integration of offshore marginal oilfield is realized successfully, and the investment is applied to the targets definitely. The research results can be used as the reference and guidance for the development of similar oilfields.
