Research On The Control System Of Oil Extraction Joint Station Based On PLC

At present, injecting CO2 into the subsurface oil and gas reservoirs is the most valid and economic choice to mitigate the greenhouse effect. When it comes to the sequestration of CO2 in oil and gas reservoirs, the capture mechanism in the reservoir and the geological conditions have to be taken into account. The related technologies of CO2 sequestration in oil and gas reservoirs are mainly the calculation of the stock of CO2,the assessment of the safety aspect in sequestration, the relationship between sequestration amount of CO2 and improving oil recovery and how to banlance them. In this paper, I will use CO2 sequestration in the Canadian Weyburn Oil Field and CO2 sequestration in Daqingzijing block in Jilin Oilfield as examples,Briefly introducting the sequestration status of CO2 in oil and gas reservoirs.
