| 摘 要： | 提要 本文详细讨论了一种三维重力位场快速正反演方法。作者在前人工作的基础上,对算法作了行之有效的改进,通过对反演中的不稳定因素进行各种理论模型试算,得出保证迭代反演稳定收敛的准则,编制出可在微型机IBM—PC上运行的人机对话式自动正反演程序。本文还对各种不均质模型进行了模似计算并将该方法应用于某含油气沉积盆地的双层界面构造研究,揭示出了储油有利地段。

| Abstract: | A rapid forward and inverse calculation method of 3-D gravity anomalies is discussed in detail in this paper. The detailed algorithm is improved efficiently and the stable convergence criteria have been got by imitating unstable factors of various theoretical models.An automatic programme with mutual dialogue between the operator and the computer is created and this programme can run on the IBM -pc. micro-computers. Various inhomogeneous models are. tested by imitative calculation. we apply the inversion strategy to the study of the double-interfaced structures of an oil-bearing sedimentary basin and locate the position of the potential reservoir. |
