| 摘 要： | 渤海PL油田是位于渤海湾盆地的大型河流相油田,在其注水开发过程中,亟需准确认识注水井与生产井之间的砂体连通性,以便优化和调整注采井网,提高采收率.针对油田砂体横向变化快,纵向上薄砂体发育的特点,利用丰富的压力、水淹等生产动态资料及相位转换后赋予地质意义的地震资料综合分析砂体的连通性,进一步完善和修正了早期以地质及测井资料确定的砂体连通性分析成果,并引入注采连通率概念,用来定量表示井组范围内注水井与生产井之间的砂体的连通性.该套方法在PL油田注水优化及井网调整研究中得到了充分的体现,对其它河流相注水开发油田井组范围内井间砂体连通性研究具有一定的借鉴作用.

| Abstract: | PL oilfield in Bohai Bay is a large fluvial oil field. During water injection and oil production, it is necessary to analyze accurately the sand connectivity between injectors and producers to optimize well patterns and improve oil recovery factor. While analyzing the sand body connectivity, in view of the characteristics of great lateral change of sand bodies and enormous thin sands in vertical, we integrated dynamic production data, including formation pressure and water flooding conditions with phase transformed seismic data to perfect and adjust the previous sand connectivity results, which only based geologic and well logging data. At the same time, we use the connectivity ratio of injector and producer to analyze quantitatively the sand connectivity between injector and producer. This method has been used successfully in optimization of water injection and well pattern adjustment of PL oilfield. It can also be used as a reference for sand connectivity study in other similar fluvial facies oilfield. |
