摘要：

库车坳陷中侏罗统发育富有机质的煤系烃源岩和湖相泥页岩，具有良好的页岩气勘探前景，综合运用有机地球化学、岩石学和等温吸附等分析测试手段，系统分析库车坳陷中侏罗统富有机质泥页岩分布特征、有机地球化学特征、储层特征和含气性，初步优选了页岩气富集的有利区。库车坳陷中侏罗统陆相泥页岩厚度较大，有机质类型以II2—Ⅲ型为主，总有机碳含量平均值约为3.1%，镜质体反射率多介于0.5%~1.6%之间，具有良好的页岩气生气条件|矿物组成主要为石英和黏土矿物，黏土矿物以伊利石和伊/蒙混层为主|孔隙度介于0.5%~7.3%之间，渗透率多小于0.1×10-3μm2，属于低孔超低渗储层|储集空间主要包括纳米—微米级矿物基质孔、有机质微孔、构造微裂缝和成岩微裂缝等类型|最大吸附气量多介于0.5~8m3/t之间，含气性主要受有机碳含量和矿物成分的影响。综合分析得出克拉苏构造带北缘和依奇克里克构造带克孜—依西地区是库车坳陷中侏罗统陆相页岩气富集的有利区。

Abstract:

The Mid-Jurassic organic-rich coal-bearing source rocks and lacustrine shale developed in the Kuqa Depression are identified as potential exploration target for shale gas.The methods of organic geochemistry,petrology and tests were applied to conduct a comprehensive analysis on the organic-rich Mid-Jurassic shale distribution features,organic geochemical characteristics,reservoir characteristics and gas bearing,and the favorable areas for shale gas was also discussed.The Mid-Jurassic continental shale in the Kuqa Depression is widely distributed with great thickness and burial depth,kerogen of type Ⅱ2-Ⅲ,high TOC content with an average value of 3.1%, RO of 0.5%-1.6%,and is of great shale gas generation potential.The Mid-Jurassic shale is mainly composed of quartz and clay minerals dominated by illite and I/S mixed-layers.The shale is typical tight reservoir characterized by low porosity of 0.5%-7.3% and ultra-low permeability smaller than 0.1×10-3μm2The nano-micron mineral matrix pores,organic pores,structural fractures and diagenesis fractures are mainly developed.The maximum methane adsorption capacity varies from 0.5m3/t to 8m3/t which has positive correlation with TOC and total clay mineral content.The northern margin of Kelasu Structural Belt and Kezi-Yixi area of Yiqikelike Structural Belt are considered as favorable areas for Mid-Jurassic shale gas accumulation.
