摘　　要：三塘湖油田马46井区储层物性差、原油黏度高、自然产能低。为获得有效产能,进行了CO2吞吐开采方式研究。通过注CO2原油体系膨胀实验结合数值模拟研究对该油藏进行了CO2吞吐可行性研究和吞吐参数优选。CO2吞吐矿场试验和跟踪评价显示CO2吞吐在马46井区已见到较好效果。The Ma 46 well block in the Santanghu oilfield has poor reservoir property,high oil viscosity and low natural energy.CO2 huff and puff has been studied in order to obtain effective productivity.The research involves feasibility study and parameter optimization of CO2 huff and puff for this reservoir through performing CO2 injection experiment in conjunction with numerical simulation.The field test and follow-up assessment of CO2 huff and puff has shown good result in the Ma 46 well block.
