Abstract

The embodiment of the invention discloses a dense sand rock conductivity analysis method and system. The method comprises the following steps: performing rock electricity testing on a rock core sample, and acquiring physical parameters and conductive parameters of the rock core sample; acquiring a gray scanning image of the rock core sample, and establishing a three-dimensional digital rock core according to the gray scanning image; according to the three-dimensional digital rock core, acquiring aperture distribution information of the rock core sample; according to the aperture distribution information, reestablishing a trapezoid pore structure; and performing oil-driving simulation experiments with different displacement forces, and confirming water saturation and pore resistance corresponding to different displacement forces. By adopting the dense sand rock conductivity analysis method and system disclosed by the embodiment of the invention, rapid and accurate dense sand rock conductivity analysis can be achieved.

Description

technical field [0001] This application relates to the technical field of unconventional oil and gas well logging, in particular to a tight sandstone conductivity analysis method and system. Background technique [0002] In recent years, the output of conventional oil and gas resources has declined year by year, and the exploration and development of unconventional oil and gas energy has attracted great attention from the energy circles at home and abroad. Tight oil is an important unconventional oil resource, which is the main driving force for the increase of my country's oil reserves. [0003] Saturation is an important parameter to evaluate the resource potential of tight oil and gas reservoirs. This process usually needs to be completed by combining resistivity curves, saturation models and rock-electric experiments. A large number of studies have shown that tight oil reservoirs have complex pore structures and high oil saturation. Since the complex pore structure bri...
