Problems solved by technology

At present, the efficiency of viscosity reducers is being vigorously studied both at home and abroad. It can be seen that their objective economic benefits. Many viscosity reducers do not have temperature resistance. However, when producing oil, gas injection (injection of high temperature Steam), which is beneficial to reduce the viscosity, but many viscosity reducers do not have temperature resistance, so after injecting steam, the viscosity reducer without temperature resistance will lose its effectiveness
[0006] At the same time, in order to obtain a higher viscosity-reducing rate, some enterprises use a large amount of carbon tetrachloride in the production of viscosity-reducing agents, which is likely to cause corrosion of refining equipment, so large-scale use is not allowed

Abstract

The invention relates to a viscosity breaker and a production technique thereof, belonging to the technical field of oil production assistants. The viscosity breaker comprises meerschaum, epoxy octyl stearate, sodium polyacrylate, sodium hydroxide, a surface modifier, propanol and water. The meerschaum, epoxy octyl stearate, sodium polyacrylate, sodium hydroxide, surface modifier, propanol and water are proportionally mixed to obtain the viscosity breaker, so that the visbreaking rate of the thick oil can reach 99.9%. Besides, after the viscosity breaker is put in a 400-DEG C high-temperature closed vessel and aged for 36 hours, the visbreaking rate of the viscosity breaker can still reach 99.3% above.

Description

[0001] technical field [0002] The invention belongs to the technical field of petroleum production aids, and in particular relates to a viscosity reducer and a production process thereof. Background technique [0003] In recent years, international crude oil prices have continued to rise, oil demand has continued to rise, ordinary crude oil has been continuously consumed, and then heavy oil resources have attracted people's attention. Stimulated by oil prices, the mining technology and operation management level of heavy oil in various countries has been rapidly improved, which not only reduces the cost of heavy oil mining, but also makes marginal heavy oil and bitumen reservoirs, which were considered to be of no value in the past, an effective resource with economic value. Heavy oil refers to crude oil with an annual temperature greater than 50mPa·s at the reservoir temperature. According to the viscosity, heavy oil can be further divided into ordinary heavy oil (50-1000...
