摘　　要：酒泉盆地青西凹陷柳沟庄地区发育泥质白云岩裂缝型油藏,其储层具有非均质性强、横向连续性差等特点。本文依据地层形变与裂缝发育之间关系的原理,在细致分析形变地层地震属性特征变化的基础上,利用GeoEast解释系统提供的属性分析、属性压缩、玫瑰图、烃类检测和数据融合等技术,开展裂缝预测、裂缝单元(体)分析及油气检测,取得了较好的地质效果和经济效益。Fractured reservoirs in argillaceous dolomite in Liugouzhuang,Qingxi Depression,Jiuquan Basin are characterized by strong heterogeneity and literal discontinuities.Based on geological deformation and fractures,we predict fracture reservoirs in argillaceous dolomite with seismic attributes provided by GeoEast.Fractured reservoir prediction,fracture unit analysis,and hydrocarbon detection are carried out by approaches such as multi attributes,attribute compression,roses,and data fusions.And good achievements are obtained.
