根据不同区域地层的漏失特征，建立描述漏失特征的漏失模糊物元指标体系，结合从优隶属度原则分析各漏失模糊物元的权重复合物元，确立每个区域的漏失特征与标准状况的欧氏贴近度的关系，欧氏贴近度越大则该区域漏失量越小，由此评价不同区域漏失分布规律。利用该方法对塔中1号断裂构造带不同区域的4口典型漏失井进行了评价分析，计算结果与实际漏失情况基本相符。该方法为区域地层漏失状况钻前预测提供了新的思路。

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.
