%X 苏里格气田致密气水平井在开发过程中，气田不同区块、同一区块中不同井甚至同一口井中不同暂堵段暂堵压裂效果差异较大，影响暂堵压裂效果因素不清楚。明确主控因素对优化暂堵压裂工艺具有指导意义。采用灰色关联度法与Spearman相关性分析法对主控因素进行分析，结果表明：1) 影响苏里格气田暂堵压裂效果的主控因素主要为：每段液量、簇间距、簇数。2) 簇间距、簇数及每段用液量存在最优区间，需要进一步优化；暂堵时机单一，时机前移或者后移可能会对暂堵效果产生较为明显的影响。<br />
During the development process of tight gas horizontal wells in the Sulige Gas Field, the temporary plugging and fracturing effects vary greatly in different blocks of the gas field, different wells in the same block, and even different temporary plugging sections in the same well. Factors affecting the temporary plugging and fracturing effects are not sure. Clarifying the main control factors has guiding significance for optimizing the temporary plugging and fracturing process. Gray correlation method and Spearman correlation analysis were used to analyze the main control factors. The results show that: 1) The main controlling factors affecting the temporary plugging and fracturing effect of the Sulige Gas Field are: liquid volume in each section, cluster spacing, and cluster number. 2) There are optimal intervals for cluster spacing, number of clusters, and liquid consumption in each section, which need to be further optimized; the timing of temporary blockage is single, and moving the timing forward or backward may have a more obvious impact on the temporary blockage effect.
