What is the role of oilfield defoamer?
Petroleum is a very precious resource. It is widely used as fuel, and is widely used in various types of automobiles, tractors, and ship power machinery; It can be used as lubricating oil to reduce wear of various machinery or instruments and ensure efficiency; It is a solvent for rubber, paint and other industries, and can be used to wash machines and parts. Foaming problems often occur in oil fields. Too much foam will bring many adverse effects. Therefore, oilfield defoamers are needed to solve foam problems.
There are many reasons for the emergence of foam in the oil field, including three basic elements, namely, gas-liquid contact, containing foam aids, and foaming speed higher than foam breaking speed. In the process of oil field exploitation, due to the operation of equipment, a large amount of air is drawn into the oil, which is difficult to escape in the high viscosity system, resulting in gas-liquid two-phase mixing and foam; The strong foaming property of heavy oil is due to the large amount of gum asphalt in the heavy oil, which contains surface active components and high surface viscosity.
The foam produced by the oil field is large in quantity, high in viscosity and strong in stability. If it is not eliminated in time, it will bring adverse effects. Too much foam will cause false liquid level in the separator, making it difficult to control the liquid level of the separator, causing gas or oil leakage in the oil circuit of the separator, and at the same time, producing very large metering errors in oil well metering; The production of foam also affects the progress and process of oilfield chemical exploitation, leading to lower efficiency and higher cost. Therefore, it is necessary to add oilfield defoamer in time to remove unnecessary foam.
The oilfield defoamer produced by RISE Chemical has lower surface tension and higher surface activity, and the petrochemical defoamer can inhibit or eliminate foam substances in the system. The defoamer for oil industry has strong defoaming ability and low dosage; The chemical property of the oilfield antifoam is very stable, which will not affect the basic properties of the system, will not react with it, and has strong oxidation resistance; Moreover, the oilfield defoamer has good dispersibility and permeability, and can be well miscible with oilfield foaming system, without oil bleaching and precipitation.
