准噶尔盆地PX地区石炭系火山岩储层储量参数研究
Reserves parameters of Carboniferous volcanic rock reservoirs in PX Block, Jungger Basin
摘要
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.关键词
