What are the uses of petrochemical additives
Usage of petroleum additives:
Used for oil field drilling, wax removal, corrosion inhibition, anti swelling, unblocking, etc.
emulsifier
The molecular structure is designed by a variety of surface active groups. It has outstanding emulsification effect can form a stable oil lotion in water. The use of emulsifiers can form a reverse emulsified oil-based drilling fluid system. The rheological properties of oil-based drilling fluid are stable, with high YP/photovoltaic electrical stability, low high-temperature high-pressure water loss, strong aging before after anti pollution. This system is widely used. The system between 40 200 ° C has outstanding applicability. The density scale ranges 0 92 to 2.30 grams per cubic centimeter. The emulsifier is mainly oil-based drilling fluid emulsifier. It can ensure high stability low dosage of the drilling fluid system.
Main components of organic phase drag reducer: hydrogenated polyisoprene, polyisobutene, random polypropylene, block copolymer of butadiene styrene, copolymer of ethylene vinyl ester, polyacrylamide Add 3% to 0.9% aqueous solution to crude oil, with a controlled content of 2-5ppm, ethylene propylene copolymer, a comb like copolymer of olefins, etc
Usage: Drag reducing agents have been widely used in various fields have achieved outstanding results. For example, after adding polyethylene oxide to the fire hose, using a smaller diameter hose can still maintain the flow rate of water, making it easier for firefighters to carry; By participating in drag reducing agents in farmland irrigation, irrigation power can be improved irrigation area can be expanded; Adding drag reducing agents in water oil transportation systems can save energy consumption; In flood discharge pipelines, using drag reducing agents can also improve flood discharge power when flood peaks appear; In oil well drilling, adding polymer drag reducing agents to injected water can greatly improve the injection rate. The drawback of polymer drag reducing agents is that they are expensive, resistant to shear stress, are prone to degradation. When used repeatedly remotely, the drag reducing power will decrease.
Wax removers, chemical agents that can remove wax deposits, can be divided into three categories: oil-based wax removers, water-based wax removers, oil-in-water wax removers. Wax removers are generally used in oil wells in oil fields to remove wax deposits in oil pipes increase oil production by unblocking the pipes. Oil based wax removers are chemical solvents with strong ability to dissolve white wax. Water based wax removers are composed of water, surfactants, mutual solvents, alkaline substances. Oil in water type paraffin remover is composed of water-based paraffin remover as the connecting phase, oil-based paraffin remover as the dispersing phase, non-ionic surfactant as the emulsifier.
