Concrete is an indispensable tool in oil mining, geological survey and other operations. It can remove the concrete at the bottom of the well, increase the wellbore pressure, prevent blowouts, protect the well wall, prevent well wall collapse, and can also make the well wall collapse. Keep the working environment tidy and improve work efficiency. However, due to the fact that the mud itself is made of a mixture and there are problems such as high pressure and high speed stirring during the operation, a large amount of foam appeared and delayed the work process.
Therefore, concrete defoamer was developed to address this situation. The defoamer is a defoamer synthesized from polyether and other ingredients and is suitable for defoaming under conditions of strong acid and alkali. It can achieve rapid defoaming and defoaming, and control the generation of foam.
1. Effects of using concrete defoamer:
Concrete defoamer can quickly dissolve into the mud system to fully integrate the defoaming molecules and the foaming system, reduce the stability of the surface of the foaming system, quickly eliminate foam, and improve the recycling of mud. efficiency, speeding up the drilling process. At the same time, a large cause of foam is formed by the high-speed operation of drilling equipment mixed with formation leakage gas. Therefore, while eliminating foam, defoaming molecules can improve the chemical stability inside the drilling mud so that it will not easily interact with the leaked gas. It reacts with impurities and forms a protective film on the surface of the mud to prevent the mud from foaming again due to various impurities.
2. How to use concrete defoamer:
Concrete defoamer can be added directly; it can also be added after dilution. However, during the dilution process, attention should be paid to the ratio of water to the added original solution, and the concentration of the diluted product should be controlled to avoid ineffective use due to excessive dilution. good. The conventional addition amount is 0.1~0.3% of the total foaming system, but the specific amount should be determined after sampling tests of the actual mud liquid. After adding the defoaming agent, the defoaming effect of the defoaming agent should be observed in time and the amount should be changed to achieve the best result. Effect.
And protective measures must be taken during use to avoid direct contact with the human body, which may cause harm to the human body. Colleagues need to pay attention to that unopened and unused defoaming agents should be sealed and stored in a cool, ventilated place to prevent defoaming caused by long-term storage. Invalid.
