【摘要】：準(zhǔn)噶爾盆地車排子地區(qū)石炭系火山巖油藏勘探取得重要發(fā)現(xiàn),但針對該區(qū)的火山巖儲層尚未開展系統(tǒng)的儲量參數(shù)研究。綜合運用巖心、巖屑、試油、測井和地震資料,采用巖性約束"孔隙-裂縫"雙介質(zhì)模型方法,對準(zhǔn)噶爾盆地PX井區(qū)石炭系火山巖巖性、儲集空間及儲層儲量參數(shù)進(jìn)行分析,并針對不同巖相建立火山巖雙介質(zhì)儲層物性參數(shù)定量解釋模型,定量計算火山巖儲層的物性參數(shù)和含油飽和度。結(jié)果表明:研究區(qū)火山作用形成的巖石主要有凝灰?guī)r、火山角礫巖、玄武巖和安山巖,可劃分為爆發(fā)相、溢流相及火山沉積相3種巖相類型;孔隙和裂縫是準(zhǔn)噶爾盆地PX井區(qū)重要的儲集空間,測井綜合識別裂縫方法適用于火山巖裂縫型儲層預(yù)測;巖性約束的"孔隙-裂縫"雙介質(zhì)模型適用于火山巖儲層儲量參數(shù)的優(yōu)選和儲量計算。
[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.
