Oilfield Chemicals Additives-Oilfield Drilling Defoamer
In the oilfield drilling process, drilling mud is the working fluid that plays the role of lubrication, cooling, arm protection, transferring drilling rock chips and balancing the bottom pressure. When the drilling mud completes the corresponding mission, it will produce a large amount of waste mud, the main components of which are bentonite, drilling rock chips, water and a variety of chemical additives. Due to the high number of pollutants such as alkali, salt and oil contained, it is difficult to treat, and the oil-bearing sewage is affected by various factors, which is easy to produce foam and accumulation, which is very unfavorable to the orderly oilfield process.
So, in the face of this foaming problem, how should we solve it? In fact, adding a certain amount of oilfield drilling defoamer will be able to eliminate and suppress the foam in time, and we can continue to see the specific situation.
The main function of oilfield drilling defoamer
Oilfield drilling defoamer is an organosilicon polyether copolymer defoamer. The defoamer can quickly solve the problem of foam generated by drilling mud to avoid adverse effects on the construction of oilfield processes. Its main characteristics include the following.
1.Quickly eliminate foam: oilfield industrial drilling defoamer is an organosilicon polyether copolymer defoamer, defoamer can resist high temperature and pressure, high shear force and strong acid and alkali, quickly solve the problem of foaming in the process of oilfield drilling mud, sand slurry, mining and refining.
2.Long-lasting foam inhibition: Oilfield industrial drilling defoamer is chemically stable, and can still play the effect of foam inhibition after eliminating foam, and the length of foam inhibition can be more than 48 hours.
3. Improve the quality of industrial products: too much foam will affect the efficiency of the pump and slow down the production process, after adding the right amount of oilfield industrial drilling defoamer, it can effectively avoid these problems, so that the quality and appearance of industrial products are protected accordingly.
4. Reduce the ineffective loss of energy: foaming will affect the normal operation of the machine, and even pile up overflow leading to waste of resources, adding oilfield drilling industry defoamer can deal with foam in a timely manner to better save energy and reduce consumption and protect the environment.
The correct use of oilfield drilling defoamer
Oilfield industrial drilling defoamer can be added directly to the foaming system to ensure uniform dispersion of the defoamer; it can also be added in batches to provide a lasting effect of foam inhibition. If it is to be diluted, the storage of diluted solution should be within 8 hours as much as possible. According to the viscosity, temperature and agitation of different foaming systems, 10ppm is the economic dosage and 30-200ppm is the ideal dosage.
