叠偏剖面的断层解释方法

针对二维地震叠偏剖面解释中存在的断层解释问题，提出了叠偏剖面断层解释方法，阐述了断点解释、组合断层与层位闭合、断面闭合及归位次序之间的关系。叠偏剖面的断层解释方法包括断点解释方法和断点组合方法，体现了断层解释与层位闭合、断面闭合及归位次序之间的关系。该方法突出了立体解释的观点，空间问题要用立体的解释方法，在深度域解决断层问题有利于得到可靠结果。

A method for fault interpretation based on stacked migration section

To cope with the fault interpretation problem in interpretation of 2 D stacked migration section, a method is proposed in this paper for fault interpretation. The relations between fault contacts, compound fault and horizon tie, fault plane tie, and migration sequence are illustrated in detail. This method emphasize the viewpoint of 3 D interpretation, that is, we must tackle spatial problems with spatial interpretation procedures. More reliable results can be achieved by solving fault problems in depth domain. The application of the method to data interpretation over past years, especially in meticulous interpretation of structures in development seismic survey, has yielded good results.
