The Mud Gas Separator is a special equipment for the degassing of gas-immersed drilling fluids. It belongs to the category of atmospheric degassing and is based on the principle of atmospheric degassing. However, it is the primary degassing equipment for processing gas-immersed drilling fluids. The main difference is that it is mainly used to remove large air bubbles with a diameter bigger than 3mm ejected from the drilling fluid. Large bubbles refer to most of the expansive gas in drilling fluid that fills a certain section of the wellbore annulus, with a diameter of about 3-25mm. These large air bubbles can easily cause blowouts and even spray out of the surface of the turntable. In addition, the Mud Gas Separator mainly relies on the impact of gravity to realize the separation of gas and liquid, while the degasser adopts the vacuum principle and the centrifugal principle. The amount of gas processed by the degasser is much less than that of the Mud Gas Separator, but the gas removal is more thorough. Usually, there will be small bubbles in the drilling fluid treated by the Mud Gas Separator. After passing through the Shale Shaker, it needs to enter the vacuum degasser for degassing.
Mud Gas Separator atmospheric-pressure hydrogen sulfide-proof Mud Gas Separator is made of high-quality materials, which can effectively prevent the erosion of harmful gases and ensure safe man-machine production. When the drilling fluid has gas invasion, its specific gravity and viscosity will deviate greatly, which cannot meet the drilling requirements; if it is not dealt with in time, it will cause a well kick or even a blowout accident. The combination of the Mud Gas Separator and the electronic ignition device can ensure the smooth progress of the drilling process.
Mud Gas Separator is a special equipment for gas intrusion drilling fluid. It is a necessary mud gas separator for drilling. When the drilling fluid has gas invasion, its specific gravity and viscosity will deviate greatly, which cannot meet the drilling requirements. The combined use of ZHF series drilling fluid gas separator and electronic ignition device can ensure the smooth progress of the drilling process.
Working Principle of Mud Gas Separator for Mud Recycling System
Blowouts occur when drilling with low-density drilling fluids. When the drilling fluid is circulated from the bottom of the well to the wellhead, the bubbles expand exponentially. Therefore, when the drilling fluid returns with a large amount of natural gas invaded downhole, the expansion of the bubbles will cause the Blowouts.
The Mud Gas Separator is a very important sepatator. The gas-immersed drilling fluid enters the shunt cone inside the equipment from the liquid inlet of the equipment, and the gas is separated from the drilling fluid through the shunt and impact of the shunt cone. The free gas is discharged through the gas outlet of the topping. The distance between the outlet of the exhaust pipe and the wellhead is determined and matched by the site (generally not less than 50 meters), and is led to a safe place, and the degassed drilling fluid is discharged into the circulation tank.
When the equipment is used and not used for a long time, it is necessary to open the sewage outlet valve at the lower end of the equipment to discharge excess mud to prevent agglomeration and affect the normal use of the equipment.
