A method and electronic equipment for predicting reservoir physical property parameters

Abstract

The invention discloses a method and electronic equipment for predicting reservoir physical property parameters. The method includes: obtaining multiple geological physical property parameters of a target area, and establishing the target area based on multiple geological physical property parameters of a sample area in the target area Rock physics model: Based on the rock physics model of the target area and multiple geological and physical parameters of the target area, a single-parameter inversion optimization problem based on Bayesian theory is constructed, and the optimal problem of single-parameter inversion based on Bayesian theory is solved Optimize the problem to obtain the target candidate area; based on the rock physical model of the target area, construct a multi-parameter joint inversion optimization problem based on Bayesian theory for the target candidate area, and solve the target candidate area based on Bayesian theory The multi-parameter joint inversion optimization problem is obtained to obtain the predicted value of multi-parameters in the target candidate area.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a method for predicting reservoir physical property parameters and electronic equipment. Background technique [0002] Since the mid-20th century, researchers have done a lot of research on the relationship between reservoir physical parameters and elastic parameters. [0003] On the one hand, researchers such as Doyen and Fournier established data-driven empirical models based on multivariate statistics. The construction process of this kind of multivariate statistical model is simple and can fit the actual data well, but this kind of model is often strongly dependent on well logging data and lacks reliable physical interpretation. On the other hand, scholars such as Gassmann and Biot established rock physics models based on the mechanical theory of porous media. This type of model can finely describe the physical laws between different parameters, but in the in...
