2D seismic data acquisition technology of shale beds in Pengshui area

为探索彭水地区页岩层二维地震资料采集技术,借鉴以往地质研究成果,针对下古生界页岩层,建立地质模型,运用基于模型的观测系统设计技术和定量分析方法,对地震采集观测系统参数进行论证研究。在观测系统参数初步选定后,采用试验对观测系统参数的合理性进行优化,并通过正演分析、使用射线追踪方法对所设计的观测系统进行分析,得到一套合适的页岩气资源勘探采集技术,对下一步勘探开发工作具有积极意义。

In order to explore 2D seismic acquisition technology for shale beds in Pengshui area, learning from previous geological research achievements and aiming the shale beds of lower Palaeozoic, geological model was built up and the layout design based on model and quantitative analysis were used to demonstrate and study the seismic acquisition parameters. After the preliminary selection of layout parameters, experiments were carried out to optimize the rationality of the layout parameters. Meanwhile, forward analysis and ray tracing method were used to research on the designed layout. A set of suitable acquisition technique of shale gas exploration was obtained, which provided positive significance to the further development of shale gas exploration.
