稠油油藏注超临界二氧化碳驱油影响因素分析
Analysis on Influential Factors of Supercritical Carbon Dioxide Flooding in Heavy-Oil Reservoirs
摘要
Abstract
Focused on a single block in the Liaohe Oilfield,a series of laboratory experiments,with the aid of orthogonal experimental design,were conducted to clarify the influence of some important parameters during supercritical CO2-EOR flooding in heavy oil reservoirs.And the influence weights of different variables were analyzed to the CO2 flooding efficiency.The results show that there is an increasing tendency of CO2 flooding efficiency with the growth of permeability,injected gas volume and reservoir temperature,and the decrease of crude oil viscosity.Permeability has the greatest weighting factor of influence on the oil recovery,followed by oil viscosity,amount of injected gas,temperature and pressure of reservoirs in a descending order.Finally,this paper summarized several problems during CO2 injection process,and recommended the relevant measures based on literature review.关键词
