摘要:
利用岩心观测、铸体薄片、物性分析等资料,分析了春风油田石炭系火山岩储层的岩性、岩相、储集空间类型及储层物性,研究了岩性、岩相、风化淋滤及断裂对储层的影响。研究表明,该区石炭系储层岩性主要为火山熔岩和火山碎屑岩,以溢流相安山岩、爆发相热碎屑流亚相火山角砾岩储层最发育,溢流相玄武岩、爆发相空落亚相凝灰岩次之,火山沉积相储层不发育; 纵向上储层分布于石炭系顶部风化壳内,风化淋滤作用使风化壳具有不同结构,其中顶部的土壤带、水解带物性差,中间的淋滤带和崩解带物性好,是主要的储层发育段; 储层储集空间类型主要为溶蚀孔隙、风化缝和构造缝,表明风化淋滤和断裂作用对储层改造起到关键作用。春风油田石炭系有利储层主要分布于风化壳和裂缝发育区,为典型的“缝-壳”型火山岩储层。
Abstract:
By the means of core observation, cast sheet, physical property analysis and other information, it was analyzed the lithology, lithofacies, reservoir space types and reservoir properties of the Carboniferous volcanic reservoirs in Chunfeng Oilfield,and then it was studied the effects of lithology, lithofacies, weathering, leaching and fracture on reservoir. Research result shows that the lithology of reservoir is mainly volcanic lava and volcanic clastic rock, where the effusive andesite and the volcanic breccias of pyroclastic-bearing lava flow subfacies of explosive facies are the most developed, the effusive facies basalt and the tuff of airfall subfacies of explosive facies are the second, and the volcanic sedimentary facies is undeveloped. In longitudinal direction, reservoirs are distributed in the top of the Carboniferous weathering shell. The weathering and leaching made different structures of weathering crust, where the top soil and hydrolysis layers have poor reservoir properties, the intermediate leaching layer and calving belt are main reservoir development areas with good physical properties, and the main types of reservoir space are dissolved pores, structural seams and weathering seams. So this shows that the formation of volcanic reservoirs is mainly affected by weathering, leaching and cracks. The favorable reservoirs of Carboniferous in Chunfeng Oilfield are mainly distributed in the weathering crust and fracture development area, which are typical "fracture-weathering crust” volcanic reservoirs.
