Study on methods of repeated hydraulic fracturing comprehensive evaluation about CBM vertical Wells
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.
