Abstract

The invention discloses a three-axis layout drawing method for analyzing the compound influence law of three factors and its application. The method comprises the following steps: drawing a triangle, each side of the triangle represents an influence factor; dividing a grid in the triangle; When dividing the grid, select a side to divide it into n parts, start from the node of each part of the side, draw grid lines parallel to the other two sides, and the other end of the grid line ends at the triangle On the other two edges, the real coordinates of the grid nodes formed on the plane Cartesian coordinate system are (x i ,y j ), the change mode of i and j is increasing from top to bottom and from left to right on the triangle; determine the change trend of each influencing factor, and determine the three-axis coordinates of the grid nodes; calculate the network according to the three-axis coordinates According to the value of the grid node, the color temperature map is drawn and the contour line is drawn. The invention can clearly and intuitively reflect the change trend of the influence results when the three variables change simultaneously.

Description

technical field [0001] The present invention relates to the technical field of multi-factor composite influence law analysis, in particular to a three-axis layout drawing method for analysis of three-factor composite influence law and its application. Background technique [0002] Low-permeability gas reservoirs are widely distributed and have considerable reserves. How to efficiently develop low-permeability gas reservoirs has become the focus of attention. Due to the characteristics of low porosity, low permeability and strong heterogeneity in low-permeability reservoirs, the flow of gas in them shows complex seepage phenomena. If the conventional diameter mining method is used for development, the output is generally low, and it is difficult to achieve the purpose of economic development. Therefore, the low-permeability gas reservoirs at home and abroad are basically exploited by horizontal wells. [0003] Productivity analysis of gas wells in gas reservoirs is an impo...
