| description | The invention relates to the technical field of oil field oil production engineering and particularly belongs to an optimization design method for a CO2 flooding and injection well production and killing system. The problems that the leakage amount of solid-free well killing fluid of CO2 flooding and injection well production is large, and the cost stays at a high level are solved effectively. Theoptimization design method mainly comprises the following steps that the leakage amount Vf under the conditions of different pump injecting pressures Pb and pump injecting flow rates Q is calculated,the values of Vf are compared, and the combination of the values of injecting parameters Pb and Q when the value of Vf is the minimum is the optimal parameter combination. According to the optimization design method, on-site timely adjusting can be instructed to be conducted according to real-time monitoring data, and the advantages that operability is high, the significant theoretical referenceis provided for on-site ope |
