Optimization of Polymer-surfactant Flooding Parameters in Maling Jurassic Low Permeability Reservoir
The low-permeability Jurassic reservoir in Changqing Maling has been in the middle and high water cut stage after long-term development of water injection.In order to improve development efficiency and further explore a new way to enhance oil recovery of the reservoir, a significant development test and a polymer-surfactant flooding study were carr
