【摘要】 塔南凹陷是塔木察格盆地的中南部的次级构造单元,具有烃源岩厚度大、有机质丰度高、热演化充分、油气保存条件好以及油气资源丰度高等特点,是增储上产的潜力地区。利用地震、测井、钻井、试油以及区域资料,分析铜钵庙组与南屯组的主要油气藏类型,认为研究区主要发育的构造-岩性复合油气藏、断块油气藏、背斜油气藏以及岩性油气藏分布情况与构造带的展布密切相关,油藏分布主要受中部和西部控陷断裂的影响呈北东向条带状分布,并在对典型井实际数据的统计分析基础上,查明了目的层的原油性质与地层水物性特征。最后通过典型油藏剖面分析,明确了研究区油水纵向与横向的油水分布规律与控制因素。更多还原

【Abstract】 South Tarim depression is a sub-tectonic unit located in south central part of Tamtsag basin and a potential region of considerable production and reserve with thick source rocks,abundant organic matter,fully thermal evolution,good oil and gas preservation conditions and highly abundant hydrocarbon resources.Based on the analysis of the main reservoir types of Tongbomiao and Nantun groups by using seismic,logging,drilling,testing,and regional information,this paper came to the conclusion that the distribution of lithologic composite reservoirs,fault-block reservoirs,anticline reservoirs and lithologic reservoirs were closely related to the distribution pattern of tectonic belt,and that reservoirs distributed like strips in north-east direction mainly influenced by subsidences and fractures in the central and western part.Combined with the statistics and analysis of practical date of typical wells,this paper also identified oil properties and formation water physical properties of the target reservoir.Based on the analysis of typical reservoirs’ profiles,the paper finally identified the distribution rules and controlling factors of longitudinal and transverse oil&water in the research area.更多还原
