Abstract:

Climate change centering on carbon dioxide(CO2) emissions and energy security centering on the shortage of oil resources are two major problems restricting the sustainable development of China's social economy. In order to solve the bottleneck of both the CO2 capture and the great improvement of recovery factor of low permeability reservoir, the related technology researches have been carried out in Shengli Oilfield, forming the supporting technologies such as CO2 capture, safe long-distance transmission, reservoir engineering optimization design, the injection-production process design, design of surface gathering and oil displacement and environmental monitoring, and building an industrial-scale demonstration project for flue gas CO2 capture, oil displacement and underground storage of coal-fired power plants. The industrial tests show that the cost of the new MSA technology is 35 % lower than that of the traditional MEA technology. Over 31×104 t of CO2 have successfully been injected into the reservoir, with the cumulative oil increment of 8.6×104 t, and 28×104 t of CO2 storaged in G89-1 block. The central well area has increased the recovery rate by 9.5 %, and the recovery rate is expected to reach 17.2 %.

Key words: CO2 emissions, CO2 capture, CO2 flooding, CO2 storage, enhance oil recovery(EOR)
