Each mud gas separator has limitation on much it can safely handle volume of gas. If the volume of gas exceeds the maximum limit, gas can blow through into the rig. It is very important that you must estimate gas flow rate on surface based on pit gain and kill rate in order to see how much expected gas on surface. This will be the limitation on how much you can circulate for well killing operation. You can estimate the volume gas on surface by using well control kill sheet provided by several companies. You need to ensure that the vent line should be as straight as possible with a larger ID in order to minimize back pressure while venting the gas out.

Oilfield drilling Poor boy degasser that removes air or gases (methane, H2S, CO2 and others) from drilling liquids. There are two generic types that work by both expanding the size of the gas bubbles entrained in the mud (by pulling a vacuum on the mud) and by increasing the surface area available to the mud so that bubbles escape (through the use of various cascading baffle plates).

In the oilfield, people have several names for the mud gas separator as “poor boy degasser” or “gas buster”. While drilling, the mud gas separator should be lined up at all times and filled with the present mud weight currently used.

DCZYQ series Mud gas separator(Poor Boy Degasser) is professional equipment to treat the gas invade mud. When the drilling mud result gas invade, the proportion of its weight and viscosity have a greater deviation not to meet the requirements of drilling.

The serious situation is that would cause Chung well, and even blowout accident occurred, if not to treat it timely. ZYQ series Mud gas Separator combined with the Electric Ignition Device can be used to ensure the drilling process smooth. It is divided into the normal pressure Mud gas separator and pressure auto-control Mud gas separator, according to the pressure.Mud gas Separator is your best choice to prevent drilling mud invasion.

Mud gas separators are commonly used during oil drilling operations, particularly in situations when extraction is likely to yield a large volume of gas. Mud gas separator captures and separates large volume of free gas within the drilling fluid. If there is a “KICK” situation, this vessel separates the mud and the gas by allowing it to flow over baffle plates. The gas then is forced to flow through a line and vent it to a flare.

Mud gas separator

The mud gas separator skid may include one or more fluid conduits for use with a drilling rig, including an integrated vent line, a high pressure line, a low pressure line, a standpipe manifold, a rig water supply line, a diesel line, an air line, and a rig water return line. The integrated mud gas separator skid may be mechanically coupled to a drilling rig. The integrated mud gas separator skid may need only one crane lift to be mechanically coupled to the drilling rig.

Performance Features of Mud gas separators:

DC Solid control can supply the model of DCZYQ800, DCZYQ1000 and DCZYQ1200 mud gas separator. If you have any requirements please feel free to contact us.

The mud gas separators should be able to handle a high proportion of mud solids and may experience hydrate plugging as a result of gas expansion through the choke. Designs based on conventional process practice, involving a float controlled liquid dump valve and a control valve to regulate gas pressure are not suitable because of the accentuated risk of malfunction due to plugging and the consequent need to provide a relief valve which itself may plug. Mud gas separator designs should therefore be based only on a liquid seal system matched to an adequate gas vent.

Liquid Throughputs

The volumetric flow capacity of the system should be based on an adequate gravitational rate from the mud gas separator. A typical liquid capacity of 6 barrels per minute of 12 pounds per gallons drilling fluid of average viscosity is a guide for vertical mud gas separator.

Liquid seal design

The liquid seal ensures that separated gas vents safely without breaking through to the mud tanks. The seal may be in the form of an external U-tube or may be based on a dip tube extending into a tank, usually the trip tank. The liquid seal hydrostatic pressure must be monitored against the back pressure of the gas vent line in the mud gas separator. It may be integrated as part of an instrumentation control system for the whole system.

Anti-Siphon Line

If the liquid seal is based on a U-tube design, an independent vent pipe, preferably 6 inches nominal diameter or larger, should be fitted at the highest point of the pipe work to avoid siphon effects and as a back-up to dispose of gas carried through the U tube liquid seal. The secondary vent need not extend to the top of the derrick. It should never be tied onto the primary vent.

Relief lines

All surface gas handling systems should have a means of diverting the flow from the choke and kill manifold through overboard relief lines and isolating the mud gas separator. In a blow-out situation, this may be the last resort to allow evacuation of personnel from the drilling rig. The pressure rating of the piping and valves on overboard lines should not be less than the pressure rating of the buffer

Drilling fluid gas-liquid separator is the first stage professional equipment to treat the gas invade mud. It is mainly used to remove the big bubbles with the diameter of about ≥Φ3mm.Most of these bubbles are the expanded gas filled in the drilling fluid in annular of wellbore. It would cause well kick if mot to remove it timely.

Operation principle

Drilling fluid with gas invades goes into the separator at the import tangentially and drops to a series baffles along the inner wall. After collision to increasing the contact area, It flows downward and become to a turbulent state which makes gas separate from mud and the free gas passes through the top of tank and discharged from the gas export. The length of gas export pipe can be determined at site and be induced to the safe place. The drilling fluid without gas will flow into the circular tank.

How to Installation

1. Generally, the separator is installed on the surface next to the 1# tank. The surface should be flat and stable.
The main body is lifted vertically to the surface by crane at the auriculars on the top of main body and then put down slowly. Three places on the top of the main body are pulled tightly by the steel string to assure the main body to be vertical to the surface.
2. After installation, Exhaust line the 2# channel 60-80mm distance of the mouth of a well.(The line is oneself, if needed to manufacturer provide, explain away to the speak for).Connecting the 3# import to the rotary prevention or throttle conduit and close the 4#waste export, open the 7#mud export and connect to 1# mud tank by the pipe.
3. When in moving, disassemble the pipe and loose the tightened string. Lift the top of the main body to make the auricular plane by crane. The ladder can be used as bracket in this situation.

Maintenance

Discharge the mud in the separator totally when in spare time and other are not needed.

The mud gas separator is designed to remove gas from the mud/fluid before it is transferred to the shale shaker system. It separates gas out of the mud after the gas comes out of hole.

The mud gas separator is strictly used for well control only. There are some events that this equipment is utilized in a well testing operation. Additionally, inspection for the gas buster must be performed frequently the same as other well control equipment.

People tends to forgot about this since it is just only a vertical separator tank without high pressure specification like BOP, choke manifold, valves, etc. Erosion is one of the worst enemies to the vessel like this and it can be seen at the points where the drilling mud impinges on the internal wall vessel.

Each mud gas separator has limitation on much it can safely handle volume of gas. If the volume of gas exceeds the maximum limit, gas can blow through into the rig. It is very important that you must estimate gas flow rate on surface based on pit gain and kill rate in order to see how much expected gas on surface.

Working principle of the mud gas separator

The drilling mud with gas mixture in the bore hole is transferred by mud return lines to the inlet of the mud gas separator, allowing it to impinge on a series of baffles which separates gas from drilling mud. The free gas flows into the flare line to be burned and the mud discharges to the shale shaker and to the mud tank.
