Coal seam Water injection Pump

Improving the permeability of coal seam with pulsating

Improving the permeability of coal seam with pulsating Jul 01, 2018· The pulsating load is applied earlier in water injection technologies of coal seams and petroleum reservoirs. Zhao (2008) proposed a variable frequency method for coal seam water injection, with a pulsating pressure of 0–15 MPa, to achieve pulsating water fracturing with a high pressure and form a new interrelated pore-fracture network within the coal seam. A method of rapid determination of gas pressure in a coal Sep 01, 2017· The water-injection pump was turned on until the water pressure reached 3–4 MPa; thereafter, it was turned off. The viscous liquor pump was then started; in this step, it is vital to ensure that the pressure is greater than the gas pressure of the coal seam. CN102645396A - Test method for improving coal rock The device comprises a three-spindle seepage test room, a plunger pump, a water injection pump, a water tank and a direct-current power supply. The device is simple in structure, reliable

Water injection pump | Sulzer

Water injection pump Sulzer HPcp ISO 13709 / API 610 Type BB5 radially split barrel pumps are used for water injection, offshore crude oil shipping, and remote pipeline services. The Sulzer HPcp pump is the leader in ultrahigh pressure applications. CN102645396A - Test method for improving coal rock The device comprises a three-spindle seepage test room, a plunger pump, a water injection pump, a water tank and a direct-current power supply. The device is simple in structure, reliable in performance and accurate in measurement. The method is remarkable in effect, after the electroosmosis action, the permeability of the coal rock sample can Study on Permeability Improvement Technology by Injecting Gas extraction cycle is too long in low-permeability coal seam. In order to solve the problem, the basic principle about gas drainage drilling for gas injection technology is studied to increase permeability. And the mathematical model is established. Gas is injected into the low-permeability

Upstream | Sulzer

Upstream Sulzer High-performance pumps from Sulzer provide cutting edge solutions for the production Sulzer is an industry leader in water injection for oil production, crude oil, refined product and LPG pipeline; and API 610 pumps for the refining and petrochemical services. Oil and gas production Oil sand Shale / coal seam gas Subsea Related CO2 Injectivity in a Multi-lateral Horizontal Well in a to effectively pump out the water produced from the coal seam. This CBM production well was converted to CO 2 injection well by removing the pump and tubing. Tubing was reinstalled with two sets of pressure and temperature transducers attached at the end tubing.
