目前的地震资料解释、速度分析、时深转换往往在一个解释软件上完成,而每个软件都有其优缺点,对于构造复杂地区来说,只用一个解释软件进行构造成图不能满足工作的需要。对Geo Quest和Landmark解释软件中的两个绘图模块CPS- 3和Z- MAP Plus的优缺点进行了分析,对速度分析模块In Depth的功能进行了完善,实现了两绘图模块间的数据传输。在地震剖面的基准面与速度谱的基准面不一致的构造复杂地区,提出了一种时深转换及构造成图新方法:在In Depth模块中建立高精度的三维速度场,时深转换在速度谱基准面上完成,结合绘图模块CPS- 3和Z-MAP Plus优势来编制构造图,并利用Earth Vision可视化软件对构造成果图进行三维可视化显示;此方法首次应用于C工区,获得成功。

 At present, seismic data interpretation, velocity analysis, time-depth conversi ons usually are completed on one interpretative software. As we know, every inte rpretative software application has its advantages and disadvantages. Only using  one kind of interpretative software in complicated structure area can't meet th e needs of each work assignment. We analyze the advantages and disadvantages of  two mapping modules CPS-3 and Z-Map Plus in GeoQuest and Landmark respectively . The functions of the velocity analysis module InDepth have been perfected and  data transmission between CPS-3 and Z-Map Plus was achieved. With in a complic ated structure area of inconsistent datum plane between seismic section and velo city spectrum, a new method of time-depth conversion has been used to make the  structural map. A 3D velocity field of high accuracy is found and time-depth co nversion is completed on a datum plane of velocity spectrum to make the structur al map by combining CPS-3 and Z-MAP Plus. Three dimensions visual software Ea rth Vision is applied to display final structural map. This method was applied a nd achieved success in the C area.
