摘要
受到地震分辨率的限制,河流相薄而窄的砂体展布很难预测。根据苏里格气田的实际情况,在地震保幅处理、水平井地质录井、修正等时试井等资料的基础上,运用单砂体模式识别技术确定砂体展布,并建立了苏里格气田盒8气藏砂体分布的地质模型。通过研究对比运用多种技术方法综合确定河流相薄而窄小的砂体是切实可行的,所建立的砂体分布地质模型为开发井位优选提供了依据。
It is very difficult to forecast the thin and narrow sandstone of fluvial facies because of the limit of seismic distinguish ment. In the Sugeli gas field,some methods such as seismic relative amplitude preserved processing, geological loggmg of horizontal wells, the equal- time well test modification and determination of sandstone distribution with identifing technique of single sandstone were used and the sandstone distributing geological mode of He-8 gas resevior of Sugeli gas field was established. Result showed that it is possible to ascertain the thin and narrow sandstone by means of muilt-techniques. The geological mode proved evidence for the location of drilling wells.
