使表面活性剂增溶于超临界二氧化碳中用于三次采油
摘要：
本公开的实施方案包括用于使表面活性剂在超临界二氧化碳中增溶的方法和系统，其包括提供所述表面活性剂在其中增溶的所述超临界二氧化碳的湍流，并将所述表面活性剂注入到所述超临界二氧化碳的湍流中以获得0.01至1.0的喷流混合数。在一个或多个实施方案中，泵向通过至少部分管线移动的超临界二氧化碳提供湍流，并且与所述管线相连的注入器将所述表面活性剂输送通过限定所述注入器中的端口的表面，以将所述表面活性剂注入到所述超临界二氧化碳的湍流中，以获得0.01至1.0的喷流混合数。
摘要（英）：

Embodiments of the present disclosure include a process and a system for solubilizing a surfactant in supercritical carbon dioxide that include providing a turbulent flow of the supercritical carbon dioxide into which the surfactant solubilizes and injecting the surfactant into the turbulent flow of the supercritical carbon dioxide to achieve a Jet Mixing Number of 0.01 to 1.0. In one or more embodiments, a pump provides turbulent flow to supercritical carbon dioxide moving through at least a portion of piping, and an injector associated with the piping conveys the surfactant through surfaces defining a port in the injector to inject the surfactant into the turbulent flow of the supercritical carbon dioxide so as to achieve the Jet Mixing Number of 0.01 to 1.0.
