| Passing through 40 years exploitation,the Daqing Oil Field enter the tertiary oil recovery, the experiment indicated that extraction technology of alkali-surfactant-polymer flooding is possible to enhance recovery ratio 10% compare to polymer drive, compares the water drive enhancement recovery above 20%. Alkali-surfactant-polymer flooding is the basic technic element to safeguard the Daqing Oil Field sustainable development, but there are many unsuitable question of rising pressure equipment to adapt alkali-surfactant-polymer flooding medium, for example, the pump volume efficiency degrades, viscosity degradation enlarged to alkali-surfactant-polymer system,the quick-wear part life deduce in a big way, the technical parameter match is unreasonable, and so on.By analyzing the actuality of the booster pump of native oil field, include high power high presser multistage centrifugal pump; ram pump and booster pump.Investigate the actuality of the foreign booster pump, acquaint the actuality of the foreign booster pump, find out the difference between native booster pump technique of foreign one. Know the issue to using the booster pump in locale. Expound the basic work principle in system, analyzing the movement character of plunger, analyzing the power character of plunger. Analyzing the principle of using the polymer to thin out the crude, deeply research effecting factor of the plunger pump reduce the oil viscosity.By Make experiment of plunger case surface abrasion hardness, in the last, adopt high strength engineering plastic to act as anti-abrasive material, make the success, get great result. Changes to the fluid strength stepless speed regulation technology to the ram pump power end, reduced the ram pump vibration, enhanced the volumetric efficiency, reduced has fallen to the medium viscosity.
