摘要： A chelating agent can be used to enhance secondary hydrocarbon-fluid recovery during waterflooding operations. A composition can include a fluid and a chelating agent. The chelating agent can increase the viscosity of the fluid, which can enhance the efficacy of the waterflooding operations. The chelating agent can also form complexes with divalent cations in precipitates and solids formed by the divalent cations. The complexes can keep the cations in a soluble form until the composition exits the production well, which can prevent precipitates from forming in the production well and blocking pore throats in the production well.

摘要： Optimized enhanced oil recovery can include tuning of injection rates during a recovery operation. The injection rate of injection fluid pumped into a formation can be controlled to alternate between monotonically increasing and monotonically decreasing during the enhanced recovery operation. Injection rates can be monotonically increased to a maximum level (e.g., as defined by physical constraints of the system) and then monotonically decreased to a lower level, allowing the injection rates to be monotonically increased again. While injection rates are monotonically increasing, viscous fingering between the injection fluid and hydrocarbons can be minimized while the hydrocarbons in the formation are displaced. While injection rates are monotonically decreasing, creation of new viscous fingers can be minimized while the injection rates are decreased to levels suitable for the monotonic increasing phase of a subsequent monotonic cycle.
摘要翻译： 优化的提高采收率可包括在采收期间调整注入速度。 注入到地层中的注入流体的注入速度可以控制在增强的回收操作期间在单调递增和单调递减之间交替。 注射速率可以单调地增加到最大水平（例如，如系统的物理限制所定义的），然后单调降低到较低水平，从而允许注射速度再次单调增加。 当注入速度单调递增时，注入流体和烃之间的粘性指法可以被最小化，而地层中的烃被移位。 虽然注入速率单调递减，但可以最小化新粘性手指的产生，同时注入速率降低到适合于随后单调周期的单调递增阶段的水平。
