Oilfield Dosing Equipment System

This equipment is especially used for oilfield. Petrochemical refining system most important equipment.

1, demulsifier (emulsion breaking, viscosity reduction)           Principle:           For water bearing crude oil, viscosity increases due to the formation of water emulsions,           available           Demulsification and viscosity reduction of demulsifier,           At the same time, a water wetting film is formed on the surface of the rod tube,           Play a drag reduction role.           Usage: apply to the crude oil itself viscosity is not too high oil dosage           100-200mg/l.           2, corrosion inhibitor           Principle:           Corrosion inhibitors form a layer of adsorption film or precipitation film or oxide film on the surface of metal,           Put metal           The surface is separated from the water and acts as a protective agent. How to use: it is best to use continuous dosing           Effect of high corrosion inhibitor. Consumption           50-100mg/t, dilution times, at least           Three           Times.           3, scale inhibitor           Principle: the scale inhibitor aqueous solution is added into the water to prevent formation of scale.           Oilfield Water           Scaling is an unavoidable problem in oilfield production,           It increases with the amount of water produced in the oilfield           The problem of scaling has seriously affected oilfield production. The production process is treated by sewage reinjection,           The recycled water contains a lot of calcium,           Magnesium, as well as strontium and barium, lead to calcium and magnesium in the pipeline           Scale, corrosion and other problems. The scaling of water injection pipeline can cause the pressure of pipe blockage, pump card and water injection           Other fault,           Which results in the decrease of water injection efficiency and the reduction of oil well production. Therefore,           When the wastewater is injected back into the oilfield, the scale inhibitor of injected water must be added.           There are currently three types of production           Organic acids, polymers, carboxylic acids and polymers.           4. Wax remover: used to remove wax on the surface of rod tubes           Principle: it is composed of organic solvent (mixed benzene, light oil, alcohol ether) and active agent           Usage method:           Batch adding liquid, adding dosage, dosing cycle is determined according to the degree of wax deposition.           Matters needing attention:           Do not use hot water dilution, small dose of drugs, wax serious wells, wax is not complete, need to be fixed           Period of high dosage or hot wash.           5. Viscosity reducer           Principle:           Add viscosity reducer solution into heavy oil,           Formed by stirring; of low viscosity; relatively stable           Oil in water (O/W) emulsions. Dosage: according to the viscosity of crude oil to determine, usually in           300-800mg/l.           Directions: dilute the viscosity reducer with hot water           0.5%-1% water solution, add           Adding oil ring to the oil tank and >40% for high water containing well can reduce the water content.
