摘　　要：利用岩心常规分析资料研究准噶尔盆地滴西12井区呼图壁河组储层特征,分析油气开发过程中油气储层敏感性因素。滴西12井区呼图壁河组砂岩储层主要岩性为细砂岩和粉砂岩,储层中具膨胀性能的蒙伊混层矿物质量分数高。储集空间主要为原生粒间孔,其次是剩余粒间孔。储层孔渗性分别以中孔高渗-粗喉和中孔低渗-中喉为主。呼图壁河组储集层具有强盐敏、中等水敏和体敏、弱速敏的特征。油田开发措施:提高注入水速度;由于油层水敏为中等,注水前注入稳定剂;注意水的矿化度,防止由于盐敏造成储层的破坏。This paper studies on the Hutubihe Formation reservoir characteristics of Well Block Dixi 12 in Junggar Basin by using the conventional core analysis data. The sensitivity factors of oil and gas reservoir is also analyzed. The lithology of Hutubihe Formation sandstone reservoir is mainly fine sandstone and sihstone. The content of illite-montmorillonite mixed layer minerals with expansion is high. The main reservoir space is the original intergranular pore followed by the remaining intergranular pore. The reservoirs mainly have middle porosity, high permeability and large pore throat, middle porosity, low permeability and middle pore throat. The reservoirs also have the characteristics of high salt, middle water sensitivity and low velocity sensitivity. During the waterflooding development, improving water injection speed can be an effective measures. Due to the middle water sensitivity of reservoir, the stabilizer should be added before injecting water. Water salinity should be paid attention to during waterflooding development to prevent reservoir from damage caused by salt sensitivity.
