在勘探四川盆地的裂缝性油气藏的过程中,要求根据地震资料提供裂缝在地下分布及发育情况,因而出现了许多测定曲率的方法。本文在介绍这些方法的同时,侧重分析了这些方法的应用条件,并对估算曲率的误差进行了讨论,提出了误差改正的办法。应用地震资料拾取地层曲率参数,扩大了地震工作解决复杂地质问题的能力。 During the exploration of fractured reservoirs in the Sichuan Basin, it is required that fracture distribution and development in the underground should be provided based on the seismic data. Therefore, many methods for determining the curvature have emerged. This article introduces these methods at the same time, emphatically analyzes the application conditions of these methods, and discusses the error of the estimated curvature, puts forward the method of error correction. The application of seismic data to pick up the curvature parameters of strata has expanded the ability of seismic work to solve complex geological problems.
