东辛油田西部沙三下亚段沉积特征研究

Depositional Features of the Under Part of the Third Member of Shahejie Formation in the Western Dongxin Oil Field

通过对东辛油田西部沙河街组沙三下亚段沉积特征的研究,确定了沙三下亚段沉积相类型,进一步搞清沙三下亚段砂体展布特征,为油气藏预测提供依据。

The depositional features of the under part of the third member of Shahejie Formation in the western Dongxin oil field are researched,the sedimentary facies are further analysed and sand body distributional law are set up,which is on the basis of in the oil-gas play reservoir prediction.
