多属性分析及断裂识别技术在酒泉盆地油气勘探中的应用
|
摘要
酒泉盆地经历多期构造运动,断裂系统复杂,断层精细刻画及目标落实难度大;盆地内各凹陷具有多物源、相变快的沉积特征,发育多种类型储层,有效储层难以预测。应用GeoEast地震资料综合解释系统,针对酒泉盆地青西凹陷鸭儿峡白垩系复杂岩性,开展多属性综合分析,预测有效储层;通过构造导向滤波技术及相干、曲率等属性精细刻画营尔凹陷长沙岭构造带K_1g_1复杂断块;在"双重滤波"基础上开展相干体、曲率属性分析,提高了鸭儿峡古近系小断层识别精度,落实了古近系小断层发育体系。基于GeoEast地震解释平台,酒泉盆地多个领域地质综合研究取得进展,油气勘探获得新发现。
Jiuquan Basin undergoes multi-stage tectonic activities,and its fault system is complex,so it is difficult to determine exploration targets and to carry out fine fault description.It is very difficult to predict reservoirs due to different source materials,rapid change of sedimentary facies and various types of reservoirs.With GeoEast interpretation sub-system,we conduct a comprehensive analysis in Cretaceous reservoirs of Yaerxia in Qinxi Sag,Jiuquan Basin.Using structure-oriented filter,coherence and curvature attribute analysis,we identify the complex fault block K_1g_1 in Changshaling,Yinger Sag.With coherence and curvature analysis based on duplicated filters,we identify Palaeogene minor faults in Yaerxia and determine the Palaeogene fault development system.With the help of GeoEast interpretation sub-system,the integrated geology studies in Jiuquan Basin have made great progress and some new discoveries of the oil and gas exploration have been achieved.
