【摘要】：為提高準噶爾盆地西北緣石炭系火山巖儲層的產(chǎn)能,利用巖心、薄片、測井、分析化驗、地震資料及生產(chǎn)動態(tài)資料研究儲層特征。結果表明:該儲層可識別出4種火山巖巖性,劃分出5個巖體和3種巖相,其中,2號和3號巖體是出油較多的有利巖體,爆發(fā)相和溢流相及其控制的火山角礫巖和玄武巖是有利巖相和巖性組合;氣孔和次生裂縫是有利的儲集空間類型,裂縫溝通氣孔;物性表現(xiàn)為中孔、低滲;火山巖儲層受斷裂、巖體、巖相和裂縫的綜合控制,結合生產(chǎn)數(shù)據(jù)和地震屬性,劃分出3類有利儲層。該研究結果為研究區(qū)下一步油氣勘探部署奠定了基礎。
[Abstract]:In order to improve the productivity of Carboniferous volcanic reservoir in northwestern margin of Junggar Basin, reservoir characteristics are studied by using core, thin slice, logging, analysis and laboratory analysis, seismic data and production dynamic data. The results show that the reservoir can identify four types of volcanic rock lithology, and can be divided into 5 rock masses and 3 lithofacies, among which, 2 and 3 rock masses are favorable for producing more oil. Eruption facies and overflow facies and their controlled volcanic breccia and basalt are favorable lithofacies and lithologic assemblages; porosity and secondary fractures are favorable reservoir space types, fractures communicate pores; physical properties are mesoporous and low permeability; volcanic reservoirs are fractured. The comprehensive control of rock mass, lithofacies and fracture, combined with production data and seismic attributes, can be divided into three types of favorable reservoirs. The results lay a foundation for the next oil and gas exploration and deployment in the study area.
