Heterogeneous phase composite (HPC) flooding technology that is based on branched-preformed particle gel (B-PPG) is an important technology for enhancing oil recovery in high water-cut reservoirs. In this paper. we conducted a series of visualization experiments under the condition of developed high-permeability channels after polymer flooding. with respect to well pattern densificati... https://www.chiggate.com/tenga-flip-orb-masturbator-fashion/
