油气分布在空间中而非时间中。目前,叠前深度偏移技术在复杂断块的勘探中发挥了其独特的作用,其中,建模问题是该技术至为关键的问题,文中探讨了在东濮凹陷复杂断块中建模的原则和经验,并进行了实际应用效果分析。

Oil and gas distributes in space , not in time-domain. Prestack depth migration imaging technique has been used in the exploration of complex fault-block area. It is key to build the velocity-depth model. We discuss the principle and experience of building the model in complex fault-block in Dongpu depression.
