海上复杂河流相油田安全优化注水研究——以PL19-3油田为例

Safety and Optimized Water Injection of the Marine Complex Fluvial Oilfield:A Case Study on PL 19-3 Oilfield

安全优化注水对于海洋复杂河流相油田非常重要,海上油田的溢油进一步说明了这一点。通过断层研究、储层连通性研究、安全合理井网研究、优化注水研究以及动态监测方案编制等方面进行探索,力争找到适合海洋复杂河流相油田的安全优化合理的注水开发模式。不仅对PL这种复杂河流相油田今后开展安全、合理注水开发起到指导性作用,对其他相似油田和其他类型油田也具有一定的参考和借鉴作用。

It was very important to find an optimization and safety injection for complex fluvial offshore oilfields,especially oil spilling in marine oilfields.Faults,reservoir connectivity,study of safety and rational well patterns and optimized water injection,preparation of dynamic monitoring scheme and the other factors were studied to try to find out a suitable waterflooding development mode to this kind of complex fluvial facies oilfield.The method not only provides a guidance for carrying out safe,reasonable water injection in a complex fluvial facies oilfield in the future,also provides certain reference for other similar oilfields.
