摘要：

储层裂缝的发育特征、规模在油气藏勘探、开发中意义重大。塔里木盆地库车坳陷大北地区天然气储层具有目的层段埋深大，岩性致密，基质孔隙不发育，裂缝发育的特征，属于致密－裂缝性储层。裂缝的形成受多种因素影响，且各因素所起作用不同，在论述了各种影响裂缝形成的众多因素的基础之上，引入了模糊评判方法，对控制裂缝特征的众多因素进行了评判，确定了大北地区砂岩储层裂缝的主控因素。

关键词: 大北地区, 致密砂岩&mdash, 裂缝性储层, 裂缝控制因素, 模糊综合评判

Abstract:

The subject reservoir of Dabei gas field in Kuqa depression of Tarim basin is a tight\|fractured reservoir with the features of great depth, compact rock, extra-poor matrix porosity and developed fractures. The fracture characteristics and scale are very important in the reservoir exploration and development. The factors to form fracture are various and play different roles. On the basis of the analysis of the various factors, using the method of fuzzy-synthetical evaluation, all the factors controlling the formation of fractures are evaluated, and the main factors controlling the formation of fractures in Dabei gas field are conformed.

Key words: Dabei gas field, Tight sand-fracture reservoir, Control-fracture factor, Fuzzy-synthetical evaluation
