CO2混相驱的可行性评价
Feasibility Assessment of the CO2 Miscible Flooding Process
摘要
Abstract
CO2 flooding is a win-win measure for enhanced oil recovery and burial of greenhouse gases,which has a widely applied prospect in China. CO2 miscible flooding feasibility evaluation is an important foundation for the implementation of the field-scale. On the basis of considerable field application experience and literatures,we analyzed the negative factors of CO2 miscible flooding and pointed out an important consideration problem of CO2 miscible flooding process,as well as the development trend,and proposed feasibility evaluation of CO2 miscible flooding including:reservoir screening,laboratory measurements,reservoir simulation,economic and risk analysis,pilot testing. We hold that the feasibility assessment also needs to consider the impact of reservoir CO2 injection on spoiler or gas channeling,corrosion,calcium and asphaltene deposition, and point out that the success of CO2 miscible flooding focus is to ensure a higher mixed level of the reservoir and CO2 sweep efficiency. Based on the reservoir and engineering programs,the feasibility of CO2 miscible flooding can be ensured by the economic demonstration.关键词
