摘要
隐蔽性油气藏勘探的不断发展对地震勘探技术提出了更高的要求，以往采用的纵波勘探方法已不能满足当前油气勘探需要，很多学者将目光转向多波勘探，但目前观测系统的设计思想仍局限于纵波勘探。因此，在纵、横波联合勘探的基础上，通过实际工区的观测系统设计，从4种常用、相同采集参数不同接收线距观测系统两个方面找出最有利于多波勘探的观测系统。与此同时，分析了正交观测系统的转换波覆盖次数随接收线距变化的特征，为多波地震勘探观测系统设计提供了新思路。
Subtle hydrocarbon reservoir exploration requires higher level of seismic exploration technology. As P- wave exploration proves inadequate for current needs of hydrocarbon exploration, the attention has been turned to multi-wave exploration, but the layout design is still limited to P-wave exploration. Therefore, on the basis of P-wave and S-wave joint exploration and layout design using in actual work area a layout system in favor of multi-wave ex- ploration is found from 4 kinds of common layout systems with the same acquisition parameters and different receiving line-spacing. At the same time, the variation of converted wave fold of orthogonal layout with receiving line-spacing is also analyzed, providing new thought for multi-wave exploration layout design.
