摘要
针对神木-双山地区盒8致密气藏储层进行敏感性室内实验研究。通过敏感性矿物分析,粘土矿物含量分析,室内敏感性实验,对敏感程度及影响因素进行分析。研究表明,神木-双山地区盒8致密气藏储层岩性以岩屑砂岩和岩屑石英砂岩为主,属于低孔低渗储层;具有中等偏强速敏、强水敏、中等-弱盐敏、弱-中等偏弱酸敏、弱-中等偏弱碱敏、强应力敏感等敏感性特征。
This paper focuses on the sensitivity experiment of the He-8 tight gas reservoir of Shenmu-Shuangshan region.Through the sensitivity mineral analysis, clay mineral analysis of content, indoor sensitivity experiments,the degree and factors of sensitivity are analyzed.The result show that reservoir lithology is mainly lithic sandstone and lithic quartz sandstone.The type of reservoir is the low porosity and low permeability.The sensitivities of reservoir are medium to high velocity sensitivity,strong water sensitivity,medium to weak salt sensitivity,weak to weak medium alkali sensitivity and strong stress sensitivity.
