针对威荣页岩气田五峰组—龙马溪组一段页岩储层纵向非均质性强、精细评价难度大的问题,在深入研究威荣深层页岩气储层特征及主要影响因素的基础上,优选TOC（总有机碳含量）、含气量、有机孔占比、脆性矿物含量、黏土矿物含量、脆性指数及水平应力差异系数作为储层评价的关键参数,采用灰色关联分析法对储层品质进行定量化表征。研究结果表明：①通过计算评价参数与储层品质的关联度,明确含气量是指示优质储层的首要参数;②通过计算储层品质综合评价指标（Q）,可将储层划分为4个等级,A级储层主要为生物硅质页岩和含钙-黏土质-硅质页岩,与目前水平井靶窗位置一致,研究成果与开发实践具有较高吻合度。该方法实现了多因素影响下储层品质的精细评价,为明确优质页岩储层提供了依据,对同类型气藏的评价与开发具有借鉴意义。

The problems of strong longitudinal heterogeneity and difficulties in fine evaluation exist in shale reservoirs from the Wufeng Formation to the first member of Longmaxi Formation in Weirong Shale Gas Field. Therefore, TOC content, gas content, proportion of organic pores, brittle mineral content, clay mineral content, brittleness index and horizontal stress difference coefficient are selected as the key parameters for the shale gas reservoir evaluation, and the gray correlation analysis method is applied to quantitatively characterize reservoir quality based on the characteristics of Weirong deep shale gas reservoirs and their main influencing factors. The results show that: ①By calculating the correlation between evaluation parameters and reservoir quality, it is clear that gas content is the primary parameter to indicate high-quality reservoir. ②By calculating the comprehensive evaluation index of reservoir quality(Q), the reservoir can be divided into four levels, among which the A-level one is mainly bio-siliceous shale and calcium-bearing-clay-siliceous shale, consisting with the target window position of the current horizontal wells, and the research results are in good agreement with development practices. This method realizes the fine evaluation of reservoir quality under the influence of multiple factors, provides the basis for the objective evaluation of high-quality shale reservoirs, and has reference significance for the evaluation and development of similar gas reservoirs.
