Production sequence optimization of complex fault block oil reservoirs
Abstract
So far, production sequence determination of fault block oil reservoirs of a complex fault block oilfield still depends on the experience method which is a totally qualitative evaluation process. Therefore, a more effective and quantitative production sequence determination method is required. Through the hybrid of analytic hierarchy process method and fuzzy comprehensive evaluation method, a production sequence optimization model is built and applied to the complex fault block oil reservoirs of AGD oilfield. With the optimization, overall rankings of fault block reservoirs are calculated and the production sequence of fault block reservoirs is obtained according to the overall rankings. The results show that fault block reservoir DI1 receives the highest overall ranking and should be put into production first. The results are verified by the actual production history of AGD oilfield.
