Coal seam Water injection Pump


Water injection plunger pump - ccsctech Water injection pump can be used for water injection in oilfield and mine field. Coal seam water injection pump is a special equipment with its own advantage such as high efficiency, Small volume, Light-weight and moved easily. Coal seam after water injection operation can release the gas then insure the safety of production. Improving the permeability of coal seam with pulsating Jul 01, 2018· 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.Cited by: 65 Mechanism of water inhibiting gas outburst and the field Sep 01, 2019· During water injection, a high pressure water-injection pump was not used to increase the pressure of water injection in the coal seam. A high-pressure water injection may retain the residual high-pressure water in the coal seam,

Principal Coal seam Water injection Pump

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 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. 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

Applications Coal seam Water injection Pump

(PDF) Field investigation of using water injection through Coal seam water injection is an effective and widely used technique to promote the drainage quantity of coalbed methane (CBM) and prevent coal and gas outburst in the process of coal mining, but 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. Hebei Bangtian Mine Safety Equipment Co., Ltd. - hole Our products are mainly u

PAPER OPEN ACCESS Discussion on the Mechanism of Coal water injection pump or the water injection network; the internal power is the capillary action of the coal seam fissures and pore water, mainly depending on the diameter of the pore, the surface tension of water and the wetting edge angle of water to coal. If the pore of coal is regarded as a circular Study of Rational Water Injection Parameters of Hydraulic Injecting water in coal seam: after plugging the hole, injecting pump is used to inject high or middle pressure water in coal seam.(Fig2). According to the depth of coal seam, mechanical property of coal and firmness coefficient the maximumwater pressure is determined[6]. Fig. 2 Map of exhibition of water injection in coal seam 3. 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
