Application of reservoir prediction method in the exploitation of WC oilfield

The WC-A、B、C、D oilfields are combined development oilfield group of marine facies formation being developed,mainly using horizontal well.Compared with terrestrial formation,the marine facies formation has better reservoir stabilization and connectivity.But in the process of exploitation,the reservoir of WC oilfields has undergone great changes.We use many methods to predict the reservoir and optimize the exploitation process,such as sedimentary facies analysis,reservoir parameter statistics and correlation,seismic inversion information prediction,pilot hole drilling technique information prediction,and so on.These methods which ensured the horizontal wells drilling in nice oil formation have significant value for the development of WC oilfields.The prediction results show that these methods made great effect and have reference significance in the exploitation of marine facies oilfields.
