Abstract

The invention discloses an oilfield sewage treatment agent and a preparation method thereof. The treatment agent comprises following raw materials in parts by weight: 10-20 parts of sodium hydrogen carbonate, 20-35 parts of aluminum oxide, 22-25 parts of menthone, 30-40 parts of polyacrylamide, 10-20 parts of carbon black, 9-18 parts of calcium hydroxide, 20-30 parts of butane, 40-50 parts of polyoxyethylene octylphenol ether, 40-60 parts of sodium laurylsulfate, 10-15 parts of glycerin monostearate, 25-30 parts of propylene glycol, 15-25 parts of peroxide reductase, 20-22 parts of sodium carbonate and 10-30 parts of a surfactant. The preparation method comprises the following steps: uniformly mixing sodium hydrogen carbonate, aluminum oxide, menthone, polyacrylamide, carbon black, calcium hydroxide, butane and octyl phenol polyoxyethylene ether; and adding residual components and uniformly mixing. The oilfield sewage treatment agent can be used for effectively removing COD (Chemical Oxygen Demand) in oilfield sewage and can basically clean all ammonia nitrogen and oil.

Description

technical field [0001] The invention relates to a sewage treatment agent, in particular to an oilfield sewage treatment agent and a preparation method thereof. Background technique [0002] Oilfield sewage refers to the water injected into the oil layer from the water injection well in the oilfield exploited by water injection. Most of it returns to the ground along with the crude oil through the oil production well. This part of the water must be removed before the crude oil is transported and exported. The sewage contains crude oil. With the increase of oilfield exploitation years, the water content of water production fluid has been rising, and some blocks have reached more than 90%. These oily sewage have become the main water injection water source of oilfields. Oilfield sewage mainly includes infiltration water from oil sludge storage sites, sewage from washing equipment, rainwater from oilfield surface runoff, domestic sewage, and polluted water bodies caused by ac...
