In the process of oilfield exploitation and production, foam is a common problem. This may be due to factors such as natural surfactants in the crude oil, the mixing of gases, the action of chemical treatment agents, and intense stirring and pumping. Bubbles have a number of adverse effects:
Reduced oil recovery: Foam takes up space and affects the flow and recovery of oil.
Affect equipment operation: may lead to pump cavitation, pipeline obstruction, etc., increase equipment maintenance costs.
Interference measurement and monitoring: Affects the accurate measurement of well production, pressure and other parameters.
The role of oil field Defoamer is to eliminate these bubbles and ensure the smooth progress of production. It usually has the following characteristics:
High temperature and high pressure resistance: It can maintain good defoaming performance in the complex downhole environment of the oilfield.
Acid, alkali and salt resistance: adapt to the chemical environment under different formation conditions.
Efficient and Fast defoaming: can quickly eliminate a large number of stubborn foam.
For example, in the drilling process, the circulation of drilling fluid is prone to foam, and the use of oil field defoamer can ensure the safety and efficiency of drilling operations.
In the process of crude oil gathering and transportation, foam may also be generated due to pressure changes and chemical additives, and defoamer can ensure the smooth flow of pipelines and the stability of transportation.
In short, oil field defoamer plays an important role in improving oil field exploitation efficiency, reducing production cost and ensuring production safety.
