| 摘 要： | 系统分析了重复水力压裂选井的主要影响因素,建立了重复水力压裂选井事故树模型;根据多层次模糊数学综合评价方法结合事故树模型,建立了煤层气垂直井重复水力压裂选井评价指标体系.根据评价指标体系,对沁水盆地东南樊庄区块部分产气效果不好的煤层气井能否对二次压裂进行评价.结果表明,该方法能较好地为现场煤层气垂直井重复水力压裂选井提供理论依据,投资风险大大降低. |
| 关 键 词： | 重复压裂 煤层气 水力压裂 选井 |

| Abstract: | By analyzing main influence factors of repeated hydraulic fracturing,an accident tree model for selecting wells of repeating hydraulic fracturing was presented.According to the multi-level fuzzy synthetic evaluation method and the accident tree model,the evaluation index system of selecting wells on repeated hydraulic fracturing of CBM vertical wells was established.Based on the evaluation index system,those wells on Fanzhuang block in the southeast Qinshui basin where gas is produced poorly were evaluated.The results showed that the method could provide theory basis of selecting wells and reduce investment risk greatly. |
