【摘要】：为提高准噶尔盆地西北缘石炭系火山岩储层的产能,利用岩心、薄片、测井、分析化验、地震资料及生产动态资料研究储层特征。结果表明:该储层可识别出4种火山岩岩性,划分出5个岩体和3种岩相,其中,2号和3号岩体是出油较多的有利岩体,爆发相和溢流相及其控制的火山角砾岩和玄武岩是有利岩相和岩性组合;气孔和次生裂缝是有利的储集空间类型,裂缝沟通气孔;物性表现为中孔、低渗;火山岩储层受断裂、岩体、岩相和裂缝的综合控制,结合生产数据和地震属性,划分出3类有利储层。该研究结果为研究区下一步油气勘探部署奠定了基础。
[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.
