摘要

摘要: 以四川盆地涪陵页岩气田焦石坝区块上部气层为研究对象，在对上部气层岩相、地化、孔隙、含气性等页岩品质特征研究的基础上，分别建立了上部气层含气性、可压性评价标准，指出焦石坝区块上部气层以Ⅱ类气层为主，⑧小层含气性最优。优选页岩烃源品质、含气性、构造变形强度、裂缝、埋深5大类8项指标，建立焦石坝上部气层开发选区评价体系，将焦石坝区块上部气层划分为4个区，其中焦页A井区最有利，评价井效果好，可作为焦石坝区块上部气层开发有利区。此外，研究揭示有机质丰度、孔隙度和保存条件是影响焦石坝区块上部气层页岩气富集的主要因素，埋深与地应力和天然裂缝发育程度是上部气层气井高产的主控因素。

Abstract: The shale quality characteristics such as lithofacies, geochemistry, porosity and gas bearing properties, some evaluation standards of gas bearing properties and compressibility of the upper gas layer were studied for the upper gas reservoir of Jiaoshiba block in the Fuling Shale Gas Field. The upper gas layer in Jiaoshiba block is mainly of type Ⅱ, and the layer No. 8 has the best gas bearing properties. of five catogaries including shale hydrocarbon source quality, gas bearing capacity, structural deformation strength, fracture and buried depth were optimized, and an evaluation system for development selection of the upper gas reservoir in Jiaoshiba block was established. The upper gas reservoir in Jiaoshiba block was divided into four areas, among which the well block JY-A is the most favorable area, which can be considered to be a standard for gas reservoir development in the upper part of Jiaoshiba block. In addition, the study revealed that organic matter abundance, porosity and preservation conditions are the main factors affecting shale gas enrichment in the upper gas layer of Jiaoshiba block, while burial depth, crustal stress and the extent of natural fracture development are the main factors controlling gas well production in the upper gas reservoir.
