On oilfield defoamers
In today's world, there are many oilfield operations, and foam disturbances are often trapped. Therefore, oilfield defoamers are an essential tool for operations.
In Guanfu Oilfield mining, oil is sucked out of the oil layer, and foam is easy to form in the liquid flow. This foam is either mixed with oil and gas, and the gas escapes and wraps the liquid as a bubble; or it is formed by the interaction of impurities and chemicals in water, resulting in changes in surface tension. If the foam accumulates, many drawbacks follow.
In the oil recovery process, the foam hinders the smooth flow of the oil, reducing the oil recovery efficiency. When the pump is sucked, the foam is easy to cause the pump to empty, damage the life of the pump, and also make the oil measurement inaccurate. As for the gathering and transportation stage, foam exists in the pipeline, increasing the transportation resistance, and even causing pipeline blockage, affecting the stability of crude oil transportation. And in the refining process, foam also interferes with separation, distillation and other steps, making it difficult to achieve high quality oil.
Therefore, the ability of oil field defoamers is very important. A class of defoamers is obtained by chemical synthesis. Its molecular structure is exquisite, or has the characteristics of low surface tension, which can quickly spread on the surface of the foam, reduce the local surface tension of the foam film, causing the foam film to thin and burst. Or contains special functional groups, which interact with the active substances in the foam and destroy the stability of the foam. Such defoamers are efficient and rapid, and can eliminate a large amount of foam in a short time.
There are also natural product-based defoamers, which are made of natural materials and used after moderate processing. Its advantage is that it is environmentally friendly. After oil field operations, it is easy to degrade, and has a slight impact on the surrounding environment such as soil and water. Although the effect is slightly slower than that of chemical synthesis, it is better to be sustainable and in line with the current trend of environmental protection.
If you want to use an oil field defoamer, you should evaluate the situation. First check the cause of foam generation, analyze the composition of the oil liquid, and the working conditions of the operation. Then choose the appropriate defoamer, determine its dosage, dosing method, and timing. When adding, either directly inject oil, or disperse evenly through special devices, so that the defoamer can fully act on the foam to achieve the best defoamer effect.
In summary, oilfield defoamers are used in oilfield operations, such as boats and rivers, to ensure smooth production and improve oil quality. If they are used well, the oil field will be prosperous, the benefits can be obtained, and the environment can also be taken into account.
