摘要: 为了弄清塔里木盆地库车拗陷侏罗系致密气富集高产区和不同层系间源储配置关系,充分利用地质、岩芯分析及测井新技术等资料,结合致密气储层“三品质”各因素的测井评价方法,有效采用主控因素手段对研究区致密层开展综合应用。研究表明,盆地库车拗陷侏罗系致密气中部构造高部位的储层品质、烃源岩品质和工程品质明显好于东西部,具备良好的源储配置关系;烃源岩品质类型以Ⅰ、Ⅱ类为主;“三品质”对致密气富集高产起决定作用。通过测井、地质及工程等方面紧密结合来综合评价,为致密气有利区和压裂层优选提供可靠的依据。

关键词: 库车拗陷, 储层品质, 烃源岩, 源储配置, 工程品质

Abstract: In order to clarify the relationship between source-reservoir allocation of different layers and enrichment high-production area in the Jurassic tight gas of the Kuqa Depression in the Tarim Basin, we make full use of data of geology, core analysis and new logging technology, combined with the logging evaluation methods of the "three quality" factors of tight gas reservoirs, and comprehensively apply the tight reservoirs in the study area using the main control factors. The research shows that the reservoir quality, source rock quality and engineering quality of the high part of the Jurassic tight gas in the Kuqa Depression in the basin are significantly better than those in the east and west, and have a good relationship between source and reservoir; the quality types of source rocks are mainly class Ⅰ and Ⅱ; "three qualities" plays a decisive role in tight gas enrichment and high production. Comprehensive evaluation through close combination of logging, geology and engineering provides a reliable basis for the selection of favorable gas tight zones and fracturing layer selection.

Key words: Kuqa Depression, reservoir quality, hydrocarbon source rocks, source reservoir configuration, engineering quality
