【摘要】This paper mainly discusses the resolution and compliance rates of the inversion results and provides a reliable geological evidence for the oil and gas exploration areas which have little drilling data and great variation in the structural and sedimentary features. By using unique techniques of the EPS software, including the construction of acoustic curve, complex geological modeling and the logging constrained inversion, it carries out non-well recursive inversion, impedance inversion and reservoir parameters inversion and improves the resolution of the inversion results in study area. There is a higher copmliance rate between the sand body prediction results and confirmation wells. The results show that the connectivity of main sand bodies is poor, three sand are bodies connected each other in the plane and are vertically stacked each other. The sdudy area is a relatively favorable oil and gas exploration area.%探讨地震反演成果的分辨率和符合率,为钻井资料少、构造和沉积特征变化大地区的油气勘探提供地质依据.通过应用EPS软件独特的拟声波曲线构建、复杂地质建模及测井约束反演等技术,开展了无井约束递推反演、波阻抗反演和储层参数反演等研究工作,提高了研究区砂体反演成果的分辨率,砂体预测结果与验证井符合率较高.研
究结果表明研究区内砂体间连通性较差,3套砂体在平面上相互连接、纵向上相互叠置,是比较有利的油气勘探区.
