为深入研究地质因素、分段及射孔参数、压裂施工因素对簇间暂堵效果的影响，通过构建暂堵效果量化模型和公式，收集苏里格区块暂堵井数据76组，融合随机森林和SHAP（Shapley additive explanations）值算法，建立暂堵效果算法模型。经过对暂堵效果量化模型和公式、暂堵效果算法模型验证，发现暂堵效果量化值与产气贡献率正相关，P = 0.037，证明暂堵效果量化模型和公式的准确性高；又因暂堵效果算法模型中，训练集与测试集的MSE、MAE、R²相差微小，证明该模型的泛化能力较强且准确性高。在暂堵效果算法模型的基础之上，开展暂堵效果的影响因素分析，结果表明：总段数、渗透率、暂堵球数量、簇间距和砂比这5个因素对于暂堵效果的影响占比最大。进一步分析单影响因素，发现随总段数增加，暂堵效果增加的规律只适用于直井，对水平井不适用；随渗透率增加，暂堵效果变差；暂堵球数量< 50个、簇间距> 20 m、砂比介于18% ~ 20%，暂堵效果均可达到正向增长。研究结果可为苏里格等气田现场暂堵作业设计提供借鉴和参考。

In order to deeply study the influence of geological factors, segmentation and injection parameters, and fracturing construction factors on the temporary plugging effect between clusters, 76 sets of data of temporary plugging wells were collected from Sulig block by constructing a quantitative model and formula of temporary plugging effect, and a temporary plugging effect algorithm model was established by integrating random forest and SHAP value algorithm. After verifying the quantitative model and formula of temporary plugging effect and the model of temporary plugging effect algorithm, it is found that the quantitative value of temporary plugging effect is positively correlated with the contribution rate of gas production, with a P-value of 0.037, which proves that the accuracy of the quantitative model and formula of temporary plugging effect is high. And because the differences between the MSE, MAE, and R² of the training set and the test set of the model of temporary plugging effect algorithm are tiny, it proves that the model has a strong ability of generalization and is highly accurate. On the basis of the temporary plugging effect algorithm model, the analysis of the influence factors of temporary plugging effect was carried out, and the results show that the five factors, namely, the total number of segments, permeability, the number of temporary plugging balls, the cluster spacing and the sand ratio, have the largest proportion of influence on the temporary plugging effect. Further analysis of the single influencing factors shows that the increase in plugging effect with the increase in the total number of sections is only applicable to straight wells, but not to horizontal wells. The increase in permeability results in a deterioration of the plugging effect. The number of plugging spheres < 50, cluster spacing > 20 m, and the sand ratio of 18% to 20% can achieve a positive increase in the plugging effect. The results of this study can provide a reference for the design of temporary plugging operation in Sulig Gas Field.
