Fine Injection-production Control Technology Countermeasure Research on Reservoir Heterogeneity for Gaoshangpu Complex Fault Block Oil Reservoir

It has deep buried target,small block,long well,more oil-bearing series and strong reservoir heterogeneity for the deep complex fault blocks in Gaoshangpu. It is very difficult to recognize effective reservoir and contrast small layer. In the oil well production process,most oil wells and injection wells were commingling production. Because of ignoring horizon correspondence and the relationship between reservoir types and injection-production fine regulation,there have been a lot of problems include water cut rising and oil production decline in oil field production process. Considering single sand body lap mode,reservoir heterogeneity and injection-production connected condition,the reservoir physical property differences on the influence of the development of technical countermeasures is determined. The oilfield production can be effectively guided and achieved the purpose of efficient oilfield development.
