Abstract

The invention discloses a method for automatically reverse solving parameters of infinite formation. The method includes the steps that pressure data of the infinite formation are obtained; a double logarithmic curve is generated according to the pressure data of the infinite formation; a pre-trained parameter solving model is invoked; the double logarithmic curve is used as the input of the parameter solving model to obtain predicted values of dimensionless parameters of the infinite formation; and the wellbore parameters and reservoir parameters of the infinite formation are determined according to the predicted values of the dimensionless parameters of the infinite formation. Based on the method, parameter interpretation of the infinite formation can be completed quickly, accurately andautomatically.

Description

technical field [0001] The application belongs to the technical field of oil and gas reservoir exploitation, and in particular relates to a method and system for automatic reverse calculation of parameters of an infinite formation. Background technique [0002] The basic purpose of oil and gas reservoir research is to predict the future behavior of oil and gas reservoirs, and to find ways to increase ultimate recovery. Some engineering problems will be encountered in the process of oil and gas reservoir exploitation, such as how to establish a reliable geological model, so as to solve the problems of oil and gas reservoir evaluation, management and development based on the geological model, and ensure the dynamic prediction of oil and gas reservoirs and oil wells. Well testing is the most commonly used method to obtain formation and reservoir parameters. Generally speaking, well test analysis is to analyze and calculate reservoir parameters and wellbore parameters based on ...
