| 摘 要： | 塔里木盆地塔中地区下奥陶统风化壳岩溶型储层是主要的含油气层系,其储集空间多为后期次生改造形成的溶洞和裂缝,具有目的层埋藏深、储层横向变化大、非均质性强、储层含油气性预测难等特点。该地区已钻多口成功井和失利井的岩溶储层在叠后地震剖面上都表现为"串珠状"强振幅反射特征,根据地震剖面特征不能区分油气井和非油气井。常用叠后地震资料提取的属性,无法预测被泥质填充岩溶储层含油气性。为此,采用AVO分析技术反演得到敏感属性泊松比和流体因子,能够较好区分岩溶储层被泥质填充和未填充含油气性。实际资料应用效果与已钻井成果相吻合,表明文中所述方法可以为塔中地区油气勘探开发井位的部署提供参考依据,同时也展现了AVO分析技术在岩溶储层油气检测中的应用前景。

| Abstract: | the main composition of Lower Ordovician karst reservoirs is hydrocarbon-bearing stratigraphy in Tazhong area of Tarim Basin,it's reservoir space consists mostly of caverns and fractures resulted from secondary modification in later stages and have the characteristics of karst reservoirs such as deep buried reservoirs,great lateral variation,strong heterogeneity and complex hydrocarbon pooling conditions.Karst reservoirs of succeeded well and failure well are high amplitude,according to the characteristics ... |
