摘要

针对温吉桑地区致密砂岩储层特点,采用地震资料保幅处理与叠前反演一体化运行方式,做好地震资料和井资料处理工作,解决横波预测难题,精细井资料岩石物理分析,寻找可用于识别岩性和流体的敏感参数,加强叠前反演过程的质量监控。通过叠前反演获得纵波速度、横波速度和密度参数,进而转换为对岩性和流体敏感的其它参数,进行有效的储层预测和含油气性检测。通过叠前反演技术的研究,落实了温吉桑地区水西沟群及西山窑组3～4段砂岩储层平面分布和空间展布特征,为新的井位部署和储量计算提供了技术支持。
According to the characteristics of tight sands reservoir in Wenjishang region,an integrative operation system of seismic amplitude-preserved processing and pre-stack inversion has been applied,which is required to do seismic data and well data processing well,solve the problem of shear wave prediction,analyze petrophysical data accurately,discover sensitive parameters for lithology and fluid and enhance quality control during pre-stack inversion.Pressure wave velocity,shear wave velocity and density parameter can be obtained from pre-stack inversion,and then converted them into other sensitive parameters for lithology and fluid,and the reservoir prediction and hydrocarbon bearing measurement can be carried out effectively.Based on the study of pre-stack inversion technique,plane distribution and space display characteristics of sandstone reservoir in Shuixigou Member and 3-4 section of J2x are determined,which provides technical support for geometric arrangement of wells and calculation of reserves.
