层状构造界面问题是重力位场反演解释中最重要的经典课题之一。层状密度界面也是含油、气盆地构造重力研究中采用的一种基本数学—物理模型。诚然,作为层状介质的质量载体,只当掌握有足够的先验信息时,从理论上才有可能对某个层的重力场进行划分。层状界面的重力反演,同其他位场反问题一样,亦具有多解性和不稳定性,同时 The layered structural interface problem is one of the most important classical topics in the interpretation of gravity field. The layered density interface is also a basic mathematical-physical model used in the study of the tectonic gravity of oil-bearing and gas basin. It is true that as a mass carrier of layered media, it is theoretically possible to classify the gravitational field of a layer only if there is sufficient a priori information. The gravity inversion of the layered interface, like other inverse problems in the field, also has multiple solutions and instabilities, meanwhile,
