Abstract:
The reservoirs heterogeneity and its control on the remaining oil distribution of K1q4 in Fuyu Oilfield were researched on the basis of core analysis, physical property, logging curve and dynamic data. The results show that the reservoir heterogeneity is serious. Three types of interlayer of muddy, calcium, muddy gravel are found in the formation, and there are five vertical connection ways in the interlayer sand body. Plane porosity and pore parameters, heterogeneity coefficient distribution are obviously influenced by sedimentary microfacies and sand body distribution. The parameter value of main part of the river is high, the more it near the river channel, the lower the value of parameter is. Interlayer 's unconnected-distribution makes the reservoir heterogeneity more serious. Because of division of interlayer, the whole sand body is divided into several independent parts and the traditional remaining oil distribution of rhythm sand body changes. At the same time, the lateral distribution of the interlayer controls the range of remaining oil efficiently.
