During the project,WPS oil-displacement agent was injected by 50.

Study on cationic degree and viscosity of oil displacement agent of molecular deposition films;

Polymer oil displacement agent screening for Zhongchakou Oilfield;

Based on the geologic features of general heavy oil reservoirs, crude oil physical conditions and oilfield development situation, synthesis of a heavy hydrocarbon displacement agent, its property evaluation and laboratory simulation displacement testing are performed.

The oil-displacing agents for crosslinked polymer oil-displacing system are mainly as follows:the polymer containing monomers with heat resistance and salt tolerance,zwitterion polymer,hydrophobically associating water-soluble polymer,polymer complex system,and comb polymer.

The application performance of new polymeric oil-displacing agent is studied.

This study offers a novel idea for the development of oil-displacing agents suitable to mid-low permeability formation.
