The necessity of vacuum degasser in drilling

In the process of drilling, drilling fluid is invaded by gas or air, density is lower, viscosity higher .Drilling fluid density lower, which leads to the hydrostatic column pressure decreases, and may cause blowout, borehole collapse, etc malignant accident.It is very dangerous that drilling fluid is invaded by gas, therefore, must take measures to deal with.

After drilling gas layer, It is possible that gas invade in drilling fluid, and shale shakerdesander, desilter and mud gunmud agitator etc could be invaded in drilling fluid by air in the work process.

Drilling fluid density is decreased obviously after gas intrusion ,but the impact on the static fluid column pressure is much smaller than people imagine.Because gas of invasion is  compressible, the density of drilling fluid  is increase gradually as the well depth.

Just according to the density of drilling fluid is lower by gas of invasion, It is very dangerous that the compound method is applied to make up for the lower density decision-making and can lead to excessive drilling fluid density, pressure formation, pollution formation.

At the same time can reduce the rate of penetration, cause lost circulation, results in the decrease of borehole liquid level, and then occur blowout.For example due to the intrusion of gas, measuring the density (the actual) is /cm3.

According to the request of balance drilling, The formation pressure of well depth will be controlled by/cm3 drilling fluid , at this time if the density of recycling system is aggravated to/cm3, it can produce two kinds of consequences, one is due to increase of density, rate of penetration decline;The second is higher about 3 Mpa than the original static fluid column pressure ,there is the risk of lost circulation.

In order to restore the density of drilling fluid , the most effective means is using vacuum degasser.

Vacuum degasser produced by?OGEM?Solids?Control ?has the advantages of compact structure, reasonable design and so on.

The principle of Vacuum degasser operation

Vacuum degasser utilizes vacuum pump suction action, causes negative pressure zone in vacuum tank, under the action of atmospheric pressure, drilling mud through the suction pipe into the hollow shaft of rotor, and then through the window around hollow shaft jilt to the tank wall by spurting.

Due to the effect of collision and separation wheel, separating drilling mud into thin layer, the invaded bubble broken and gas escape. Through the vacuum pump suction and gas water separator separation, gas escape to safety zone, and the drilling mud is discharged to tank outside by impeller. Because of the main motor first start, and the impeller which connected with motor is high rotation speed, so drilling mud can only from the suction pipe into the tank, not be inhaled from drain pipe.

What is vacuum degasser for solids control?

Brief Introduction of vacuum degasser

1. The vacuum degasser is a high-efficiency in-line module that removes dissolved gases from HPLC solvents. Its unique design assures reliable continuous operation and the highest level of continuous performance available without the need for helium degassing. Up to five solvent lines may be channel offers very quick equilibration and very short startup times compared with PTFE degassing channels which have the same degassing efficiency.

2. Inside the unit, the solvent flows through a short length of Teflon AF tubing which is located in a vacuum chamber. Within this chamber a partial vacuum is maintained by a constantly running, low RPM vacuum pump. Dissolved gases migrate across the tubing wall under a concentration gradient produced by the vacuum as the solvent flows within the coil. Gases removed are expelled, and the chamber is maintained at a constant, preset vacuum level by varying the vacuum pump speed as needed.

Oilfield ZCQ Vacuum degasser

3. A special port in the vacuum pump continually flushes the pump head with a small ?bleed? of air to remove any solvent vapors which may enter the pump from the vacuum chamber. This air bleed eliminates the need for any solenoid valves within the system. This patented design results in zero vacuum hysteresis. Previous designs allowed the vacuum level.

4. It can be horizontal, vertical or round vessel. A vacuum action is created to pull in the gas cut mud. When the liquid enters the tank it will flow and be distributed to a layer of internal baffle plates designed for the mud to flow in thin laminar film and is exposed to a vacuum that forces the gas to escape and break out of the mud. The vacuum pump moves the escaping gas from the vessel discharging it to the rig’s flare or environmental control system.

Vacuum degasser

Definition:?A degasser is a device used in drilling to remove gasses from drilling fluid which could otherwise form bubble.

vacuum degasser

For small amount of entrained gas in a drilling fluid, the degasser can play a major role of removing small bubbles that a liquid film has enveloped and entrapped. In order for it to be released and break out the air and gas such as methane, H2S and CO2 from the mud to the surface, the drilling fluid must pass degassing technique and it can be accomplished by the equipment called degasser which is also a major part of a mud systems.

 

This type of degasser processes mud by accelerating fluid through a submerged pump impeller and impinging the fluid on a stationary baffles to maximize surface and thus enable escaping gas vent to atmosphere.

Vacuum Type is the most common form of degasser. It can be horizontal, vertical or round vessel. A vacuum action is created to pull in the gas cut mud. When the liquid enters the tank it will flow and be distributed to a layer of internal baffle plates designed for the mud to flow in thin laminar film and is exposed to a vacuum that forces the gas to escape and break out of the mud.The vacuum pump moves the escaping gas from the vessel discharging it to the rig’s flare or environmental control system.
