Distribution characteristics evaluation of regional leakage based on fuzzy matter-element

Depending on the leakage characteristics of the formation in different regions, leakage fuzzy matter-element indicators are established to describe the characteristics of leakage. Combined with the principle of membership favorably leakage of fuzzy matter-element, the most important complex element is analyzed. We can calculate the leakage characteristics of each region with the Euclidean proximity of standard conditions and effectively evaluate the distribution method of the leakage distribution in different regions.. Using fuzzy matter-element method, we have evaluated and analyzed the different leakage formation in the area of faults of the Tazhong I and verified that the index system and fuzzy recognition method are reasonable and scientific.
