摘　　要：在深入剖析阜东斜坡带岩性圈闭形成条件和分布规律的基础上,提出了适合于钻井稀少的低勘探程度区块的岩性圈闭预测方法.该方法主要包括如下5个要素:(1)层位标定技术(实现井震联合,确保层序地层学分析的可靠性和精度);(2)层序地层学分析法(确定岩性圈闭的有利发育层位及发育类型);(3)沉积相分析法(确定岩性圈闭的有利发育相带及具体位置);(4)叠后高分辨率处理技术(确保岩性圈闭识别的准确性);(5)波阻抗反演技术(岩性圈闭预测的核心技术).应用该方法对阜东斜坡带进行岩性圈闭预测取得了较好的效果.Based on the analyses of the formation conditions and the distribution law of the lithologic traps,the prediction method of the lithologic traps in low exploration-degree district with sparse wells are put forward.The method includes 5 elements:⑴ horizon scaling technique(combinig seismic data with well logging data to ensure the reliability and the precision of sequence stratigraphic analysis);⑵ sequence stratigraphic analysis(determining the favorable horizons and the types of the lithologic traps);⑶ sedimentary facies analysis(determining the favorable facies and the specific location of the lithologic traps);⑷ high-resolution processing technique for post-stack seismic data(to ensure the precision of the prediction of the lithologic traps);⑸ wave impedance inversion(the core technique for the prediction of lithologic traps).The applications of the method in East Fukang Slope obtain satisfied results.
