TPB used hydraulic transmission principle of hydraulic profile control and injection pump, through constant power variable oil pump (or manually variable oil pump) and the hydraulic oscillator energy transfer is realized, thus changing the traditional mechanical transmission chain, reducing the mechanical transmission links. The pump after more than 10 years of development, has become a mature technology, advanced, reliable performance and professional profile control and water shutoff device, particularly suitable for high-dose, prolonged, constant voltage water plugging and profile control operations, applicable to a variety of agents. Have been widely used in the country's major oil fields of profile control and water shutoff operation, and has become a oil field in the secondary and tertiary recovery profile, blocking water, polymer injection technology device of choice. At present, the pump has formed a different displacement, pressure demand products, maximum working pressure up to 40Mpa.
1, strong self-priming capacity, does not apply to feed the pump still works.
2, long-stroke, low stroke, piston speed low. Shear rate of the agent, agent performance is effective protection, thereby greatly improving the effect of profile control and water shutoff and polymer injection.
3, bottom hole pressure varies with displacement (inverse relationship), or based on actual industrial demand, manually adjustable displacement, reasonable protection of the reservoir.
4, wide range of pump blocking Agent, suitable for all the agents currently used materials.
5, the long service life of wearing parts, General machinery and reciprocating pumps five to 10 times, running cost is greatly reduced.
6, compared with the mechanical pump, equipped with electric power, has a significant energy saving effects.
