Abstract

The depth regulating and displacing technology to improve oil recovery efficiency in water injection oilfield is one of the most promising technical approach. Nano-micron hydrogel microspheres were injected into the depth of the injection wells, adjusting formation permeability, improving reservoir heterogeneity and increasing oil production. In this paper, polymer gel microspheres were laboratory evaluated to determine the site implementation plan and the injection process, and the field trials in six water flooding wells have proofed that gel microsphere flooding agent for water injection wells in Chaheji oilfield flooding is effective on accumulated increasing oil 4003 tons and decreasing water appears after the implementation. Using measurement pump injection technology is feasible, the average of injection 1m3 flooding agent is decreased from 11.6 to 0.29 KWH electricity.
