Pore structure characteristics of glutenite reservoir of the second member of Nantun Formation in A block of Huhenuoren Oilfield
Online published: 2013-10-08
Based on mercury injection method,this paper studied pore structure,flowing pore volume and reservoirheterogeneity.The result shows that there are three types of pore structure in the second member of Nantun Formation,including type I,type 11 and type 11,and they respectively displays single peak,double peak and flat peak.Single peak was the major type of the pore structure in the study area.Flowing pore volume in the study area is small,and the average flowing pore volume is 26.47%.The uni~rmity coeficient,sorting coeficient and fractal dimension of the pore structure in the study area were analyzed,and the result shows that the pore structure of rock in the study area has strong heterogeneity.
