WC-A、B、C、D油田是正在开发的海相地层联合开发油田群,主要采用水平井开发。海相地层较陆相地层往往具有更好的储层稳定、油藏连通的特点,但WC油田群在开发过程中储层实钻和预测相比较发生了很大变化。为了更好地进行开发,主要采用了沉积相分析预测、储层参数统计比较、地震反演信息预测、开发领眼井信息预测等储层预测方法,根据预测方法做出了多次优化调整,确保了水平井在好油层中钻进,对WC油田群的开发具有十分重要的现实意义。预测结果表明,所述方法具有良好效果,对海相油田的开发具有一定借鉴意义。

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.
