Geochemical characteristics of the Carboniferours KT-Ⅰ interval dolostone in eastern margin of coastal Caspian Sea Basin
哈萨克斯坦滨里海盆地东缘上石炭统KT-Ⅰ油层组主要发育局限海台地—开阔海台地碳酸盐沉积,间夹蒸发岩层.由于区域性白云石化作用,KT-Ⅰ油层组中白云岩广泛分布,为主要油气储集层.研究表明,白云岩中白云石为泥晶、粉晶或细晶,半自形—他形；略富钙,有序度较低(0.336～0.504);δ18OPDB值在-1.06‰～ +2.45‰之间,比石炭纪海水(δ18OPDB值介于-1‰～-2‰之间)偏正；δ13CPDB值在+3.36‰～ +5.94‰之间,与石炭…查看全部>>
The KT- I interval carbonate unit of the Upper Carboniferours is composed of a shallow marine carbonate rock with some evaporate strata, which is dolomitized in the Coastal Caspian Sea Basin, Aktyubinsk, Kazakstan. The fine-crystalline dolostone (mud-dominated) with vug porosity is the most important oil reservoir in the KT-1 interval carbonate unit. Study shows that the KT- I interval dolomite is characterized by micrite, silt or fine crystals with subhedra…查看全部>>
