摘要:
为研究孔隙结构特征对油水相渗曲线的影响，选用大庆F储层59块岩样，在相同的条件下分别进行毛管压力曲线和油水相渗曲线测定。发现根据形态特征的差异，毛管压力曲线和油水相渗曲线均可分为三类，且二者之间具有较好的对应关系。第Ⅰ类毛管压力曲线属于细歪度，孔隙分选差，毛管压力曲线中间平缓段排驱压力均大于1MPa。对应水相下凹型相渗曲线，在三类曲线中，其束缚水饱和度最大，两相共渗区展幅和水相端点渗透率最小。第Ⅲ类毛管压力曲线属于粗歪度，孔隙分选好，毛管压力曲线中间平缓段排驱压力均小于0.1MPa。对应水相上凹型相渗曲线，其束缚水饱和度最小，两相共渗区展幅和水相端点渗透率最大。第Ⅱ类毛管压力曲线对应水相下凸型相渗曲线位，所有参数均介于前两类之间。说明同一储层中，孔隙结构特征对油水相渗曲线的形态特征具有重要影响。
Abstract:
To investigate the effect of pore structure characteristics on the features of oil-water relative permeability curves，59 pieces of natural cores were used to measure the capillary pressure curves and oil-water relative permeability curves under the same conditions.According to the feature of the curves，the capillary pressure curves and oil-water relative permeability curves can be divided into three types.The type Ⅰ capillary pressure curve，with fine skewness and poor pore sorting，has a drive pressure greater than 1 MPa，corresponding to water -downward-concave relative permeability curves.The Type III capillary pressure curve，with coarse skewness and perfect pore sorting，has a drive pressure smaller than 0.1 MPa，corresponding to water-upward-concave relative permeability curves.The Type II capillary pressure curve is corresponding to water-downward-convex，of which all the parameters are between the former two types.Therefore，for a certain formation，the characteristics of pore structure have great influences on the features of oil-water relative permeability.
