Core application scenarios for oilfield emulsifiers: Emulsification control solutions adapted to the entire process.

The application of emulsifiers in oilfields spans key stages such as drilling, oil production, gathering and transportation, and storage. The emulsification requirements vary significantly across different scenarios, necessitating the selection of specific emulsifier types and formulations to achieve precise control.…

Amphiphilic oil polymers containing hydrophobic long-chain alkanes and hydrophilic polyether long-chain monomer structural units

The Bohai Sea has become one of the important bases for offshore oil and gas development in my country. The Bohai Oilfield accounts for about 70% of the total offshore oilfield production and is the largest offshore oilfield in my…

Synthesis method of alcohol ether carboxylates for oilfield enhanced oil recovery

in high-temperature, high-salinity oil reservoirs requires surfactants and polymers to possess excellent temperature and salt resistance. Therefore, alcohol ether carboxylates (AECs) with nonionic-anionic hydrophilic complex groups have broad application prospects and are widely used as oilfield emulsifiers, viscosity reducers, solubilizers,…
