One minute to understand the important role of vacuum degasser

(Summary description)The performance of drilling fluid is directly related to drilling speed, well quality, blowout, well loss and stuck drilling accident. In conventional drilling and underbalanced drilling, various gases in the formation often invade into the drilling fluid, resulting in reduced density, increased viscosity and poor fluidity of the drilling fluid. After careful analysis and field practice, the vacuum degasser is developed. Generally, it only needs one-time treatment to remove the gas mixed in drilling fluid, which can basically restore the original performance of drilling fluid, so as to ensure normal drilling and greatly improve the drilling speed. Today xiaobian is mainly to discuss the vacuum degassing machine with you.

The performance of drilling fluid is directly related to drilling speed, well quality, blowout, well loss and stuck drilling accident. In conventional drilling and underbalanced drilling, various gases in the formation often invade into the drilling fluid, resulting in reduced density, increased viscosity and poor fluidity of the drilling fluid. After careful analysis and field practice, the vacuum degasser is developed. Generally, it only needs one-time treatment to remove the gas mixed in drilling fluid, which can basically restore the original performance of drilling fluid, so as to ensure normal drilling and greatly improve the drilling speed. Today xiaobian is mainly to discuss the knowledge of vacuum degassing machine with you.

First of all, the vacuum degasser is a special equipment for treating gas-impregnated drilling fluid. Suitable for all kinds of matching, for the recovery of mud proportion, stability of mud viscosity performance, reduce drilling costs, has a very important role. At the same time, it can also be used as a high-power stirrer.

In the process of drilling, the gas carried by drilling fluid from the well affects the mud performance and has safety risks, and also affects the service life of part of the solid control equipment. Therefore, it is necessary to install a vacuum degasser to remove the gas in the mud. In underbalanced drilling, sticking occurs frequently at the depth of well, and the adhesive sticking caused by high drilling fluid density can be solved by using vacuum degasser.

The role of vacuum degasser:

1. Conclusion The field test proves that the vacuum degasser is suitable for treating the drilling fluid gas invasion of various gases in existing drilling fluid and unbalanced special drilling operation, separating glass and non-glass gas from drilling fluid, and restoring the relative density and viscosity of drilling fluid.

2. Used to deal with drilling fluid gas invasion, degassing effect is remarkable, safe and reliable.

3. The drilling fluid gas separator can only remove the free gas in the drilling fluid, and the non-free gas, that is, the gas in the drilling fluid system can not be removed. It has great value of field promotion and application.

Technical requirements of vacuum degasser:

1. The drilling fluid density is required to be relatively stable. After invasion, it should be treated in time.

2. The special liquid-gas separator is powerless to deal with the micro-bubbles of gas invasion in high-density and high-viscosity drilling fluid, and can only be processed by vacuum degasser. Therefore, it is necessary to use a vacuum degasser to treat the gas-invaded drilling fluid to maintain the drilling fluid density and achieve normal drilling.

3. It has been proved that the treated drilling fluid has returned to the density before gas invasion, thus ensuring the normal operation of the well. It can be seen from the test data that the drilling fluid density recovery effect is good after the treatment of vacuum degasser, and the recovery rate reaches the standard requirements.
