The merits of the drilling fluid performance have a direct relation with the drilling speed, the quality of well, blowout, lost circulation and sticking accidents. In conventional drilling and underbalanced drilling operation process, the formation of various types of gas tend to invade into the drilling fluid, which reduces the drilling fluid density, viscosity, liquidity becomes poor. After careful analysis and field practice, human beings developed a vacuum degasser. Usually you just need to one-time treatment to remove mixed with the gases in the drilling fluid.
Modern electro vacuum degasser consists of tank, power system, electric control system, transmission system and so on several major components. Our production of vacuum degasser adopts domestic well-known manufacturers of motor, and our valve adopts stainless steel material.
The applications of vacuum degasser used vacuum pump suction effect to cause negative pressure zone in a vacuum tank. And the mud under the action of atmospheric pressure, through the suction pipe into the hollow shaft of rotor, again by the window around the hollow shaft, the jet shaped into the tank wall. Due to the collision and separation effect, applications of vacuum degasser make the separation of drilling fluid into thin layer. The bubbles in mud broke; gas was out. Through vacuum pump suction and the separation of gas water separator, the gas will be out to safe place by the exhaust pipe with the applications of vacuum degasser. The mud will be outside the tank by the impeller discharge. Due to the main motor starts first, the impeller connected with the motor is in a state of a high-speed rotating, so the mud can only from the suction pipe into the tank, applications of vacuum degasser will not be inhaled from the drainage pipe.
The structure characteristics of a vacuum degasser is the use of vacuum pump pumping mud into the vacuum tank, and use it to make gas get out of the vacuum tank. So the vacuum pump has two different functions in applications of vacuum degasser. In the process of work, the water ring vacuum pump is always under isothermal condition, and is suitable for flammable and explosive gas suction. The vacuum degasser safety performance is reliable. Slip through the window into the walls at a high speed rotor, the bubbles break completely, and the degassing effect is good. Main motor offsets, so the center of gravity is lower. The belt drive to avoid the retarding mechanism of complicated. Application of steam separator will not result in water and gas emitted at the same time, the exhaust pipe is always open. Additional, applications of vacuum degasser still can cycle to supply water to the water inside the vacuum pump to save water. Suction tube inserted into the mud tank can be used as a powerful blender in the case of mud airless leaching.
