吐哈盆地红连地区三间房组储层特征与成岩相
|
摘要
吐哈盆地红连地区中侏罗统三间房组在油气资源方面具有巨大勘探潜力。以普通薄片、铸体薄片和扫描电镜等资料为基础,系统分析三间房组储层特征,开展成岩相研究。三间房组储层岩石类型主要有岩屑砂岩和长石岩屑砂岩;主要受压实作用、溶蚀作用、破裂作用和胶结作用等成岩作用影响;发育有6种成岩相类型,其中环边绿泥石胶结-硅质、高岭石充填-剩余原生粒间孔成岩相,高岭石、伊利石充填-石英次生加大-溶蚀孔、剩余原生粒间孔成岩相和高岭石、伊利石充填-剩余原生粒间孔成岩相是较有利的成岩相类型。
The oil and gas resources of the Middle Jurassic Sanjianfang Formation in the Honglian area of Turpan-Hami Basin have great exploration potential. Based on the data of ordinary thin section and cast thin section observation and scanning electron microscopy analysis, the reservoir characteristics of the Sanjianfang Formation and diagenetic facies are systematically analyzed. The research shows that the Sanjianfang Formation reservoir sandstones are mainly composed of lithic sandstone and feldspar lithic sandstone. The sandstones are affected by 4 kinds of diagenesis, such as compaction, dissolution, fracturing and cementation. Microscopic study reveals that there are six major types of diagenetic facies in the sandstones. Among them, the early chlorite ring, cementation, dissolution and fracturing improve the physical properties of reservoir, while the dominant diagenesis of compaction plays a destructive role in the formation of reservoir. The diagenetic facies of chlorite rim cementation-siliceous-kaolinite filling-remaining primary intergranular pore, kaolinite & illite filling-quartz overgrowth-dissolved pore-remnant primary intergranular pore and kaolinite & illite filling-remaining primary intergranular pore are favorable ones for the formation of hydrocarbon resources.
