| 摘 要： | 通过对喇嘛甸油田1974年以来的28口井986块岩样的压汞数据进行分析，分层统计了毛管压力曲线、孔隙半径大小与分布、孔隙渗透率分布峰位、峰值分布等相关参数，总结分析了喇嘛甸油田储层孔隙结构特征及不同油层的孔隙结构特征变化规律；利用岩石薄片鉴定、电镜扫描分析了粘土矿物在砂岩孔隙中分布特征。并根据孔隙特征参数对岩样渗透率范围进行了重新划分，通过压汞数据得到萨尔图、葡萄花、高台子层通用的J函数曲线，该曲线可以消除不同岩样毛管压力和饱和度曲线的差异。

| Abstract: | Based on analysis on mercury penetration data of Lamadian Oilfield with 986 rock samples from totally 28 wells since 1974,several relative parameters are determined including capillary pressure curve,pore radius size and distribution,pore permeability distribution peak value and peak value distribution.And pore structural feature in Lamadian Oilfield and variation rule for pore structural feature in different reservoirs are generated and analyzed.Distribution feature showed by clay mineral in sandstone pore are analyzed by using rock section analysis and electronic scanning analysis,and then based on pore feature parameters,to divide permeability extent for rock samples again.Common positive function curve in Saertu,Putaohua,Gaotaizi reservoirs are obtained by mercury penetration data,which can eliminate differences between different capillary pressure and saturation curves. |
