Description
Choline chloride, as a clay stabilizer, it can reduce clay swelling. Its function is achieved through ion exchange, where the cations provided by choline chloride replace the original soluble clay cations, such as sodium. Choline chloride is used to reduce viscosity expansion, which can effectively prevent expansion. In addition, choline chloride also has other advantages that potassium chloride does not have.
Advantages:
Shale inhibition: solving the problem of wellbore instability, bit mudding, and hole cleaning.
Adjusting drilling liquidity: preventing bit attachment and reducing rotation and resistance to protect the reservoir.
Non toxic and harmless: Choline is used in feed and meets environmental requirements
Compatibility with other components: Compatible with most components in drilling, completion and workover fluids.
