针对地质目标的地震仿真模拟技术应用

Simulation technology appllied for geological targets

  • 摘要: 楚雄盆地是海相碳酸盐岩油气勘探的主战场之一,其位于扬子板块的西南缘,经受多期运动改造,具有地表地形切割剧烈,地下构造和断层复杂的双复杂特点,是典型的地震资料低信噪比地区.通过多年的探索,认为采用针对地质目标的仿真模拟技术可以较好获得有效反射.该方法主要分为4个步骤:①地表高程和地下目标模型建立;②沿测线估算地质仿真剖面;③测线仿真模型的资料采集模拟;④修正测线估算模型和施工参数.

     

    Abstract: Chuxiong basin is one of the main marine carbonate oil and gas exploration regions,it located in the southwest of the Yangtze plate,and with long and multiple geological movements.So now its surface topography is complex and up and down dramatically,and the subsurface structure and the fault underground are very complex.This area has the character that both the surface complex and the subsurface are also complex,this region is a typical low s/n ration area.With many years experiences in this region,we throught that we can got better reflection data from the simulation technology,this technology has four steps:① Establish the model of the surface elevation and underground target model;② Estimate the geological simulation profile along the survey line;③Seismic acquisition simulate according to the line simulation model;④ Correct the seismic line simulation model and the operation parameters.
