勘探前期断层封闭性三维定量评价及软件研发

3D quantitative evaluation of fault sealing in early exploration stage and software development

为解决勘探前期无井区或少井区圈闭的断层封闭性评价问题,基于地震、地质、测井等资料,采用物理模拟和地震资料相结合的方法,建立无井或少井区断层封闭性定量评价体系和评价数学模型,开发相应的评价软件。海拉尔盆地乌尔逊区块应用结果表明:借助高精度三维地震信息、物理模拟实验获取区域特征参数的评价方法,可以快速有效建立无井或少井区的断层封闭性评价数学模型,解决无井和少井区断层定量化三维空间表征与评价。

In order to deal with fault sealing evaluation of traps in no well area or few well area in the early stage of exploration,based on seismic,geological and logging data,using the method of combining physical simulation and seismic data,the quantitative evaluation system and evaluation index mathematical model of fault sealing in no well area or few well area are established,and the corresponding software evaluation system is developed.The application results of Wuerxun Block in Hailar Basin show that with the help of high-precision 3D seismic information and the evaluation method of obtaining regional characteristic parameters by physical simulation experiment,the fault sealing evaluation mathematical model of no well or few well areas can be established quickly and effectively,and the quantitative 3D space representation and evaluation of fault layers in no well and few well areas can be solved.
