人们一般认为3D地震勘探设计处理是一个两步系统。第一步我们可称为初步设计。这是一些物理和成本上的计算集合,其结果可推进第二步详细的设计。 初步设计计算可包括时间采样比率、近远炮检距、接收时间、面元大小、偏移距离、CMP覆盖次数、成像区域、勘探费用和其他有关项目年度回报率的成本预算。除了后期详细设计的供应参数外,初步设计处理还可做为快速屏幕。初步设计中可行的那些项目都是为整个设计服务的。
It is generally believed that 3D seismic exploration design is a two-step system. The first step we can call initial design. This is a collection of computations that are physical and cost-effective, and the result is a second-step detailed design. Preliminary design calculations can include cost estimates for time sampling rates, near-far offsets, receive times, bin sizes, offset distances, CMP overlays, imaging areas, exploration costs, and other annual returns on the project. In addition to the late detailed design of the supply parameters, the initial design process can also be used as a fast screen. Those projects that are feasible in the initial design serve the entire design.
