摘要： 页岩气储层致密、非均质性强，在开发中须要压裂改造，准确地评价其可压裂性及其展布规律对压裂设计意义重大。以川南X地区五峰组-龙一段1亚段（龙一1）页岩地层为研究对象，以岩心测试，测录井等资料为基础，分析了反映可压裂性的指标，提取脆性指数、泊松比、杨氏模量、抗拉强度和水平主应力差为敏感参数，以层次分析法求出各自权重，构建了综合可压裂系数Icr；结合生产资料划分了Ⅰ，Ⅱ和Ⅲ级可压裂级别；开展多井可压裂级别评价与连井剖面对比，统计Ⅰ，Ⅱ级的地层厚度比，分析平面上可压裂性的变化规律。结果表明：Icr≥0.59时，可压裂级别为Ⅰ级，可压裂性最好；五峰组-龙一11、龙一12中Ⅰ级层段占比较大，是适合压裂开发的有利层段；Ⅰ级层段厚度比为0.8~0.9主要分布在N201，N209，N203，N208和N211井等井区。该研究成果为川南X地区页岩气储层水平井的部井开发提供了依据。

Abstract: Shale gas reservoir is characterized by tightness and strong heterogeneity，so fracturing is needed to increase production and transformation. Therefore，the evaluation of shale fracturing grade and its distribution rule are of great guiding significance for the fracturing design. The shale formation of Wufeng Formation-Longyi1 submember in X area，southern Sichuan Basin，was taken as the research object，based on the data of core test， logging and mud logging，the indexes reflecting shale fracturing were qualitatively analyzed，and five sensitive parameters brittleness index，Poisson's ratio，Young's modulus，tensile strength and horizontal stress difference were extracted. The weight of each parameter was obtained by analytic hierarchy process to establish the quantitative and comprehensive fracturing coefficient Icr. Combined with the production data of shale gas wells，three fracturing grades Ⅰ，Ⅱ and Ⅲ were divided. Furthermore，the evaluation of fracturing grade of multiple wells and the correlation of well-connected profiles were carried out，and the formation thickness ratios of fracturing grades Ⅰ and Ⅱ were counted to analyze the distribution features of the fracturing performance in the plane. The results show that when Icr ≥0.59，the fracturing grade of shale gas reservoir is grade Ⅰ，and its fracturing performance is the best. The fracturing profile show that the grade I interval in the sublayers 1 and 2 of Wufeng Formation-Longyi1 submember accounts for a large proportion，and core description also shows that the natural fractures in this interval are the most developed and are the most suitable favorable intervals for shale gas fracturing development. The plan indicates that the areas with intervals of grade I fracturing performance with a thickness ratio of 0.8-0.9 are mainly distributed in N201，N209，N203，N208 and N211 well areas. The research results can pro-vide a key basis for effective development of X area shale gas horizontal wells.

Key words: shale gas, fracturing property, logging evaluation, brittleness index, analytic hierarchy process, southern Sichuan Basin
