摘要
在总结国内外CO2单井吞吐成功经验基础上,根据CO2使原油膨胀、降粘、萃取原油中轻质组分、改善原油和水的流度比、改善地层渗透率(碳酸盐岩油藏)等增油机理,结合油藏、原油和储层岩石特性,应用聚类分析方法归纳并量化选井标准.
Based on summarizing successful experiences of single well huff-and-puff injection CO2 internationally, and according to the stimulate mechanism that CO2 make oil swelling,viscosity reducing,extracting lightness composition in oil, improving oil and water combined with the properties of reservoir, crude oil and reserve core,this paper finally generalize and quantify well selection standard.
