摘要:
 川南地区页岩气勘探开发实践证实，储层特征是制约深层地层非常规气实现有效开发的关键。为查明煤系储层孔隙结构和储层组合特征，以深层煤系地层为例，采用扫描电镜、液氮和二氧化碳吸附等技术手段对煤系地层煤岩、砂岩和页岩的孔隙形态、结构等进行研究，认为深层煤系地层孔隙主要由原生孔隙、次生孔隙、有机质纳米孔、微裂缝等组成，有机质纳米孔为气泡固化形成；深层煤系地层砂岩、泥岩、煤层沉积旋回性受控于沉积环境，形成泥煤砂型等多种岩性组合体；深层砂煤组合储层发育多种孔隙类型，兼有可改造性和较好含气性，具有较大开发潜力。研究结果为深层地层孔隙结构特征及组合型储层的开采提供了理论依据。

〖HJ*3〗〖WT5”HZ〗Abstract: 〖WTBZ〗〖BP(〗┣┣（英）摘要┫┫〖BP)〗The practice of shale gas exploration and development in southern Sichuan has proved that reservoir characteristics are the key to restrict the effective development of unconventional gas in deep formation. To find out the pore structure and reservoir combination characteristics of coal stratum, taking deep coal stratum as an example, this paper studies the pore morphology and structure of coal, sandstone and shale by means of scanning electron microscope, liquid nitrogen and carbon dioxide adsorption. The results show that the pores of deep coal stratum are mainly composed of primary pores, secondary pores, organic matter nano pores and micro fractures, while organic matter nano pores are formed by bubble solidification; The sedimentary cycle of sandstone, mudstone and coal seam in deep coal strata is controlled by the sedimentary environment, which forms various lithologic assemblages such as peat sand type; There are many pore types in deep sand coal combination reservoirs, which has both removability and good gasbearing property, and has great development potential. The research results provide a theoretical basis for the characteristics of pore structure in deep formation and the exploitation of combined reservoir
