摘要： A method is described of injecting CO2 into an aquifer or a depleted hydrocarbon reservoir (211) via at least one injection well (202) that penetrates said aquifer or reservoir, wherein the injection well is provided with an injection tubing (203) that is in sealing engagement with the injection well. The injection tubing terminates at or immediately above the interval of the aquifer or the reservoir into which the CO2 is to be injected and the injection tubing is provided with a fluid injection control valve (208) at or near the bottom thereof which is closed or closes when the pressure above the valve is less than a pre-set pressure value and opens or reopens when the pressure above the valve is at or greater than said pre-set pressure value, the pre-set pressure value being selected such that the CO2 in the injection tubing is maintained in a liquid or supercritical state.
摘要翻译：描述了通过穿透所述含水层或储层的至少一个注入井（202）将CO 2注入到含水层或贫化烃储层（211）中的方法，其中所述注入井设有注入管（203）与注射井密封接合。注射管终止于含水层或二氧化碳待注射的储层的间隔或紧邻其上方，并且注射管在其底部或附近设置有流体注射控制阀（208），该流体注射控制阀关闭或关闭当阀上方的压力小于预定压力值时，当阀上方的压力等于或大于所述预设压力值时打开或重新打开，预先设定的压力值被选择为使得注射管保持在液体或超临界状态。
