The low-permeability oil and gas resources of our country are quite common and abundant. Their
reserve has accounted for one-fifth of total oil reserves of our country, and their yield has constituted
the important part of national petroleum annual yield, but its development is very difficult.
Polymer gel technology is a technical method of improving sweep efficiency in recent years which
substantially increases the viscosity of the polymer solution by adding a crosslinking agent to the
polymer produced by intramolecular or intermolecular crosslinking.
