Abstract

The invention provides a carbonate rock reservoir permeability prediction method and system, computer equipment and a computer-readable storage medium, and relates to the technical field of geophysical exploration. The method comprises the following steps: collecting rock data of a carbonate rock physics laboratory; establishing a pore aspect ratio two-dimensional rock physical template accordingto the rock data; establishing a porosity-permeability model of reservoirs of different pore types by using the pore aspect ratio two-dimensional rock physical template in combination with the rock data; collecting measurement data of a carbonate reservoir for well logging or seismic measurement; and predicting the permeability of the carbonate reservoir according to the pore aspect ratio two-dimensional rock physical template and the measurement data. According to the method, the correlation between the porosity and the permeability is effectively improved, and the reservoir permeability is more accurately predicted.

Description

technical field [0001] The present invention relates to the technical field of geophysical exploration, in particular to the exploration technology of carbonate rock reservoirs, specifically a method, system, computer equipment and computer-readable storage medium for predicting the permeability of carbonate rock reservoirs . Background technique [0002] Permeability is an important physical parameter and engineering parameter of oil and gas reservoirs. It is an important index for evaluating the properties, production capacity and economic benefits of oil and gas reservoirs. Its spatial distribution directly affects the distribution, migration, ultimate recovery and productivity of oil and gas. . Therefore, it is of great significance to accurately predict the spatial distribution of reservoir rock permeability for oilfield exploration and development. [0003] Due to the influence of many factors such as sedimentation, diagenesis and structure, carbonate reservoirs ofte...
