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: |
A great deal of oil reservoirs was discovered in the Carboniferous volcanic rocks in the PX block, Jungger Basin. However, systematic researches on reserves parameters of the volcanic rock reservoirs are still very few. Based on analyses of cores, rock fragments, oil testing, well loggings and seismic data, the present contribution of the lithology, reservoir space and reserves parameters of the Carboniferous volcanic reservoirs were studied by using a 'lithology constraint porosity-fissure two-medium model '. A two-medium model of quantitative interpretation of volcanic rocks was constructed according to different types of volcanic rocks, and the physical parameters and oiliness of volcanic rock reservoirs were quantitative calculated. The results show:the volcanic eruption gemerated rocks in this area include tuffs, volcanic breccias, basalt and andesite; volcanic lithofacies is divided into 3 types of eruption facies, overflow facies and volcanic sedimentary facies; pores and fissures are important reserve space in the PX Block, Jungger Basin; method of fissure identifying based on multiple loggings is available for forecasting of fissured volcanic rock reservoirs; and the lithology constrained two-medium model is suitable for preference of reserves parameters and reserves calculation of volcanic rock reservoirs. |
