Problems solved by technology

[0002] The aging oil in Liaohe Oilfield mainly comes from the aging oil recovered from the sewage buffer settling tank and inclined plate degreasing tank of the sewage station, and part of it comes from the ground crude oil recovered from various places. 3 , the viscosity at 80°C is 1859-2684mPa·s, the content of colloid and asphaltene is high, the water content is as high as about 35%, the oil-water separation effect is poor, and the demulsification is difficult. After treatment, it is mixed with a large amount of fresh qualified crude oil and then exported. However, the water content of the aged oil after treatment is still very high, with an average water content of about 24%, which caused the water content of the joint station to exceed the standard, which seriously affected the normal operation of the joint station. production run

Embodiment Construction

[0007] describe an example

[0008] The preparation method is: firstly weigh 31% of the water according to the formula and add it into the enamel reaction kettle, slowly raise the temperature to 75-80 degrees, then add 12% of nonylphenol polyoxyethylene sodium sulfonate, stir to fully dissolve, and continue to Add 18% phenolic resin polyoxyethylene polyoxypropylene copolymer under stirring, stir for 40 minutes, then add 6% sodium dioctyl sulfonate maleate and 8% oxalic acid in turn, stir for 30 minutes and then cool Cool down to 40°C, then add 15% ethanol and 10% brine successively, stir and dissolve fully, then cool naturally to 25°C to make an aging oil treatment agent.

Abstract

The invention belongs to an oilfield aged oil treating agent, and particularly relates to a preparation method of an aged oil treating agent. According to the method, the aged oil treating agent is prepared from a phenolic resin-polyoxyethylene-polyoxypropylene copolymer, sodium diethylhexyl sulfosuccinate, nonylphenol polyoxyethylene sodium sulfonate, oxalic acid, brine, ethanol and water. The formula is characterized in that the aged oil treating agent is prepared from 18% of phenolic resin-polyoxyethylene-polyoxypropylene copolymer, 6% of sodium diethylhexyl sulfosuccinate, 12% of nonylphenol polyoxyethylene sodium sulfonate, 8% of oxalic acid, 10% of brine, 15% of ethanol and 31% of water. The treating agent has the advantages of low heating temperature, high dewatering speed and low water content in the purified oil, saves the fuel cost of the united station, does not influence the water content of the output crude oil of the united station after being doped, and ensures the smooth operation of the united station.
