Why do drilling oil fields bubble?

1. Excessive addition of surfactants

2. When the natural gas in the formation overflows, the mud will produce foam, the surfactant in the mud will stabilize the foam

3. The foam generated by the mud is too late to burst

4. Excessive addition of raw materials, etc

5. In the process of stirring, the air enters into the foam produced by the gas generated by the high-temperature decomposition fermentation of the treatment agent

Drilling mud additivesHazards of oil field bubbles:

1. Causing a fire

2. Reduce the density of drilling fluid. After the density of drilling fluid decreases, if the pressure of the net liquid column in the well is lower than the pressure of the formation, it may cause a kick blowout

3. Causing a blowout kick

Characteristics of oilfield drilling mud defoamers:

1. Strong defoaming anti foaming ability, low dosage, does affect the basic properties of the foaming system.

2. Good heat resistance, stable chemical properties, strong versatility, non flammable, non explosive.

3. Its performance can be comparable to imported products, its price has a more obvious advantage.
