【摘要】：准噶尔盆地车排子地区石炭系火山岩油藏勘探取得重要发现,但针对该区的火山岩储层尚未开展系统的储量参数研究。综合运用岩心、岩屑、试油、测井和地震资料,采用岩性约束"孔隙-裂缝"双介质模型方法,对准噶尔盆地PX井区石炭系火山岩岩性、储集空间及储层储量参数进行分析,并针对不同岩相建立火山岩双介质储层物性参数定量解释模型,定量计算火山岩储层的物性参数和含油饱和度。结果表明:研究区火山作用形成的岩石主要有凝灰岩、火山角砾岩、玄武岩和安山岩,可划分为爆发相、溢流相及火山沉积相3种岩相类型;孔隙和裂缝是准噶尔盆地PX井区重要的储集空间,测井综合识别裂缝方法适用于火山岩裂缝型储层预测;岩性约束的"孔隙-裂缝"双介质模型适用于火山岩储层储量参数的优选和储量计算。
[Abstract]:Important discoveries have been made in the exploration of Carboniferous volcanic reservoirs in Chepaizi area, Junggar Basin, but no systematic study of reserve parameters has been carried out in view of the volcanic reservoirs in this area. Comprehensive use of core, cuttings, oil testing, well logging and seismic data has been made. In this paper, the lithology, reservoir space and reservoir reserve parameters of Carboniferous volcanic rocks in PX well area of Junggar Basin are analyzed by using the lithology constrained "pore fracture" dual medium model. According to different lithofacies, a quantitative interpretation model of physical parameters of volcanic double medium reservoir is established, and the physical parameters and oil saturation of volcanic rock reservoir are calculated quantitatively. The results show that tuff is the main rock formed by volcanism in the study area. Volcanic breccia, basalt and andesite can be divided into three lithofacies types: eruption facies, overflow facies and volcanic sedimentary facies, and pores and fractures are important reservoir spaces in PX well area of Junggar Basin. The logging comprehensive fracture identification method is suitable for prediction of volcanic fractured reservoirs, and the lithology constrained "pore fracture" dual medium model is suitable for the optimization of reserve parameters and the calculation of reserves of volcanic reservoirs.
