聚合物驱主流线与分流线油藏剩余油特征
CHARACTERISTICS OF THE RESERVOIR REMAINED OIL IN THE MAIN AND DIVERSION STREAMLINES FLOODED BY THE POLYMER
摘要
Abstract
By means of collecting the oil-sand samples in the polymer-flooded main and diversion streamlines of the oilfield-development coring-detecting wells,the experimental parameters such as the viscosity,mobility,oil saturation and oil displaced efficiency were obtained,the remained oil characteristics,mobility,exploration potential and controlling factors were studied.The results show that the viscosity,mobility,oil saturation and oil displaced efficiency of the remained oil have different degrees of the heterogeneity.Compared with the diversion streamline oil reservoir,the viscosity and mobility of the main streamline reservoir are higher,the oil saturation is lower and the oil displaced efficiency is higher;the reservoir parameters influence the oil displaced efficiency in different trends and degrees,the correlation contrast of the viscosity,mobility,porosity and permeability between the main and diversion streamline remained oil reservoir is much more greater;the polymer-flooded main-streamline efficiency is controlled by the porosity and mobility,while the efficiency of the polymer-flooded diversion streamline reservoir is dominated by the porosity,mobility and viscosity;the production potential of the remained oil in the polymer-flooded main streamline reservoir is higher than that of the diversion streamline reservoir.关键词
