渤中区块河流相油藏高效开发模式总结与应用

High-efficient development pattern summary and application in fluvial facies reservoir of Bozhong block

河流相储层的储量和产量在渤海区域都占有重要地位,但受河流相沉积控制,油藏地质条件非常复杂,严重影响了油田的开发效果。而渤中区块河流相油藏的开发较为成功,因此该研究以渤中区块河流相油藏为例,对目标区块的随钻综合技术、开发井网模式、注采结构及产液结构四个方面的优化调整进行总结,初步形成适合海上河流相油田开发的模式体系,进而指导渤海其他河流相油田的开发。

The reserves and production of fluvial facies reservoir occupy an important position in the Bohai area. But controlled by the fluvial facies sedimentary, reservoir geological condition is very complex, seriously affecting the effects of oilfield development. The fluvial facies reservoir of Bozhong block are developed more successful. So based on fluvial facies reservoir of Bozhong block as an example, summarize the optimization and adjustment in comprehensive technology while drilling, development well pattern, injection-production relationship and liquid production structure of the target blocks. Build preliminarily the development system suitable for offshore fluvial facies oilfields, and to guide the development of other fluvial facies oilfields of Bohai.
