National Major Special Project for Resource Conservation and Environmental Protection - Energy saving Product Project for Improving Recovery Efficiency of High Thick and Low Yield Heavy Crude Oil

Based on the current situation and geological conditions of Tahe Oilfield, Tuha Oilfield, and Tarim Oilfield, after long-term development and research, we have successfully developed a process technology for improving the recovery rate of high viscosity and low yield heavy oil (heavy oil recovery, heavy oil demulsification oil-water separation, separated oily water treatment and reuse) and a series of products (heavy oil dispersion and drag reducer, high-efficiency heavy oil demulsifier, oilfield wastewater specific coagulant, composite scale and corrosion inhibitor, industrial sterilizer), which are at the world's advanced level, filling the gap in heavy oil extraction. Through systematic technological improvement, the recovery rate of heavy oil has been greatly improved, efficiency has been enhanced, production costs have been reduced, and resource conservation and utilization have been achieved.
