摘要:
地震资料构造解释是地球物理研究中一项重要内容,其中等值线图是主要的呈现方式。但是国内石油行业使用的进口地震解释系统大多不能提供达标(国标、行标、企标)的等值线图,需要通过独立制图软件的后处理才能达标。后处理过程包含大量的人机交互工作,导致制图工作时间约占整个地震解释项目的20%。为此,根据现有软件和待处理数据类型(等值线、断层、三维测网),提出一种多类型地震数据自动化处理成图算法,并设计完成自动成图软件,实现对解释图件多种数据的集成式处理。软件实现GeoFrame工区数据一键式导出及等值线、断层、测网等多种数据自动化处理要求,大幅度简化了绘图过程中的地震数据处理流程。目前软件已经广泛应用到实际生产项目中,提升了约90%的制图效率并有效降低了成图错误率。
Abstract:
Structural interpretation based on seismic data is a critical task in geophysical research,and the results are mainly manifested as contour maps.However,most imported seismic interpretation systems used in the petroleum industry of China fail to provide contour maps that meet national,industrial,or enterprise standards, making post-processing necessary for the resultant contour maps using independent mapping software.The post-processing process involves many human-computer interactions,with the time for mapping accounting for about 20% of that for seismic interpretation.Therefore,based on the existing software and the types of data to be processed (contours,faults,and three-dimensional grids),this study proposed an automatic processing and mapping algorithm for multi-type seismic data.Furthermore,it designed the automatic mapping software for the integrated processing of various data of maps to be interpreted.The software can achieve one-click export of data of a GeoFrame working area and the automatic processing of multi-type data such as contours,faults,and grids,greatly simplifying the seismic data processing flow in the mapping process.Presently,the software has been widely used in practical production projects,improving the mapping efficiency by about 90% and effectively reducing the mapping error rate.
