Do you know the defoaming principle of defoamers used in oil fields?
In the process of oilfield exploitation, there will be associated gas exploitation, also called oilfield gas. It refers to natural gas that is dissolved in crude oil or coexists with crude oil in gaseous state and is extracted with crude oil at the same time. The basic purpose of oil and gas development is to extract the oil and gas stored in the deep oil and gas layers as much as possible. Improve recovery and reduce costs. At the same time as oil production, a certain amount of natural gas will be extracted. While gas production can increase the production capacity of condensate oil. However, in the process of gas production in oilfields, the problem of foaming is often encountered. The generation of foam will bring certain harm, so it is necessary to use defoamers for oil fields to solve the foam.
Foaming is a relatively common phenomenon in the process of gas production in oilfields. The overflow of natural gas in the formation will lead to the coexistence of two phases of gas and liquid in the oil field, resulting in a large amount of foam; a certain proportion of chemical additives such as fracturing fluid, drainage aid, foaming agent, etc. will be added during gas production. These additives contain a large amount of surface Active substances have foaming properties, which can easily lead to foaming; in addition, the gas production process in oilfields is affected by temperature changes and pH changes, which is one of the reasons for foaming.
A large amount of foam enters the pipe network, resulting in an increase in the friction of the pipe network and an increase in the pressure of the pipe network. As a result, the production of gas wells is affected, the production fluctuates greatly, and the pipeline network is blocked. If the foam is not eliminated in time, it will enter the downstream device and pollute the downstream chemicals, such as desulfurizer, dehydration dose, etc. Excessive foam will affect the progress and normal procedures of gas production in the oil field, resulting in a decrease in gas production efficiency, resulting in excessive production costs, affecting the stability of the oil and gas production system, and causing blowouts.
The petrochemical defoamer developed and produced by Ruichi Chemical has the characteristics of fast defoaming speed, long foam suppression time and low dosage. After the antifoam is used, it can quickly eliminate all kinds of foam in the gas production in the oil field, without oil drift or precipitation. The defoamer for oil industry has good water solubility and dispersibility, and the defoamer for oil field also has good chemical stability, which will not affect the progress and effect of oilfield exploitation.
