摘要:
喀拉扎背斜位于准噶尔盆地南缘,发育侏罗系油砂。在喀拉扎背斜侏罗系头屯河组首次发现6个油砂露头点,并实施地质调查井1口(喀油砂1井),揭示油砂储层累计厚度超过30 m。通过钻井岩芯编录、岩石薄片鉴定、扫描电镜观察、铸体薄片观察和测井等方法,对油砂储层的沉积环境、岩性、物性和储集空间类型等进行了研究。结果表明:油砂储层位于中侏罗统头屯河组,主要包括中细砂岩油砂储层和粗砂—细砾岩油砂储层;中细砂岩油砂储层为厚层沉积岩储层,沉积相属于曲流河相河床亚相的边滩沉积微相,储集空间以原生孔隙为主,孔隙度和渗透率为中—高孔、高渗范畴;粗砂—细砾岩油砂储层为特厚层沉积岩储层,沉积相属于曲流河相河床亚相的河床滞留沉积微相,储集空间以次生孔隙为主,孔隙度和渗透率为中孔、中渗范畴。总之,喀拉扎背斜侏罗系头屯河组储层有利于油砂的富集与储存,是准噶尔盆地油砂资源新的潜力区。
Abstract:
Kalazha anticline is located in the southern margin of Junggar Basin, and oil sand develops in Jurassic. 6 outcrops of oil sands in Kalazha anticline have been found in Jurassic Toutunhe Formation for the first time. One well has been drilled in the oil sand-bearing layer, and the thickness of oil sand layers found is more than 30 m. Based on the core recording, identification of rock sections, SEM, identification of casting sections and core logging, the sedimentary environment, lithology, physical property and space types of oil sand reservoirs were studied. The results show that the oil sand reservoirs belong to Middle Jurassic Toutunhe Formation, including middle-fine sandstone and coarse sandfine conglomerate oil sand reservoirs; the middle-fine sandstone oil sand reservoir is thick sedimentary rock, and the sedimentary facies is marginal microfacies of riverbed subfacies, meandering river facies, and the reservoir space is mainly primary pore, and the porosity and permeability are middle-high and high, respectively; the coarse sand-fine conglomerate oil sand reservoir is extra thick sedimentary rock, and the sedimentary facies is riverbed retention microfacies of riverbed subfacies, meandering river facies, and the reservoir space is mainly secondary pore, and both of porosity and permeability are middle. In general, the reservoirs in Jurassic Toutunhe Formation in Kalazha anticline are favorable for the enrichment and storage of oil sands, and will be one of the potential areas of oil sand resource in Junggar Basin.
