    • Systems and methods for enhancing production of viscous hydrocarbons from a subterranean formation. The methods may include heating a hydrocarbon solvent mixture to generate a vapor stream, injecting the vapor stream into the subterranean formation to generate reduced-viscosity hydrocarbons, and producing the reduced-viscosity hydrocarbons from the subterranean formation. The methods also may include selecting a composition of the hydrocarbon solvent mixture by determining a threshold maximum pressure of the subterranean formation, determining a stream temperature at which the vapor stream is to be injected into the subterranean formation, and selecting the composition of the hydrocarbon solvent mixture based upon the stream temperature and the threshold maximum pressure. The systems may include a hydrocarbon production system that may be configured to perform the methods and/or that may include an injection well, an injectant supply assembly, and a production well.
    • 用于增强从地层中产生粘性烃的系统和方法。 所述方法可以包括加热烃溶剂混合物以产生蒸汽流,将蒸气流注入到地下地层以产生降低粘度的烃,以及从地下地层产生降低粘度的烃。 所述方法还可以包括通过确定地层的阈值最大压力来确定烃溶剂混合物的组成,确定将蒸汽流注入到地层中的流温度,以及选择烃溶剂的组成 基于流温度和阈值最大压力的混合物。 该系统可以包括可以构造成执行方法和/或可以包括注入井,注射剂供应组件和生产井的烃生产系统。
