摘要
笔者分析了海拉尔盆地乌尔逊凹陷大磨拐河组储层的8口井18个井段的试井资料,观察了230个铸体薄片,统计了上千个孔喉参数,归纳出七种孔喉微观结构模型,系统地研究了储集性及影响因素,认为本区储层岩石属于中孔低渗型,弱亲水,复杂的孔隙结构网络及比表面值大是影响油气运移、聚集的重要因素。
In order to study the reservoir properties and their influencing factors of the Damoguaihe formation of theWuerxun depression in Hailaer basin, the arthur analyzed 18 well tests from 8 wells, 230 thin sections, and aboutone thousand pore throat parameters, resulting in 7 pore throat structure models. The reservoir rock is of moderateporosity, low permeability and weekly water wet. The complex pore structure pattern and large specific surface areaare important factors affecting hydrocarbon migration and acumulation.
