S Block Mechanism Of Asp Flooding And Application Research

S block reservoir thickness is larger,the thick oil reservoir is mainly composed of river sand body mutually superposed to form,the river sand body origin is more,the formation of the main types by bending the distributary channel sand,braided river sand body,low bend of distributary channel sand.In S block accounted for more of these types of formation,and the form such as reservoir thickness and continuity of form diversification,serious influence S block reservoir development.In the process of S block reservoir development,under the condition of the reservoir water cut is higher,after oil reservoir's residual oil content is bigger,still has great potential for development and mining.This article mainly aims at S block reservoir as the research object,incentive of asp flooding a study on the impact of the first,second analysis of various oil displacement system,and analyzes the influence factors of oil displacement system,and then through the base table activator of hydrophobic associating polymer fluid surname man,viscosity and interfacial tension,shear performance are discussed,such as discusses the synergistic effect of each agent system in oil displacement system,secondly,to S block of interfacial tension from asp flooding system is analyzed and studied.Model based on the indoor core displacement experiment,carried out the S block asp flooding system of oil displacement experiments,the displacement of S block asp flooding system of influencing factors in the process of analysis and research,respectively for S block interface performance of asp flooding system,permeability,wettability,etc.,this paper analyzes the factors which influence the displacement efficiency,finally S blocks to site construction as an example analysis of asp flooding,asp flooding in S area system development effect and the potential is analyzed,in view of the development effect of construction scheme optimization.
