本文较系统地阐述了川中—川南过渡带地震资料的特殊处理成果(包括瞬时振幅包络、瞬时相位,亮点及波阻抗等)应用于勘探油气藏的原理和方法,并论述了含油气地震反射异常的识别标志。文中通过实例说明了这些方法的正确性与可行性。同时,笔者认为本区油气具有点多、层多与分散的特点,是应用地震勘探寻找非背斜油气藏的有利地区。 This paper systematically expounds the principles and methods applied to the exploration of oil and gas reservoirs by the special treatment results (including instantaneous amplitude envelope, instantaneous phase, bright spot and wave impedance) of seismic data in the central Sichuan-Sichuan transitional zone, Abnormal identification mark. The examples illustrate the correctness and feasibility of these methods. At the same time, the author thinks that the hydrocarbon in this area is characterized by a little more, more layers and more scattered, and is a favorable area for applying seismic exploration to find non-anticlinal reservoirs.
