Abstract
The invention discloses the preparation method of petroleum crude oil thinner, the viscosity break ratio solving existing petroleum crude oil thinner is undesirable, especially on paraffin content without impact, causes exploiting the problem being difficult to.The present invention includes: step one, be added to the water mix homogeneously by 2 (3,4 dihydroxy phenyl) ethamine, lignin；Step 2, heating, and in heating process, it is added sequentially carbon tetrachloride, o-tert-butylphenol, polyisobutene succinimide, methyl formate, poly alkyl alcohol ethylene oxide ether sulfates ester and sodium hydroxide, mix homogeneously；Step 3, added after, reach 60～80 DEG C in temperature and keep at least 2h；Step 4, dried below 100 DEG C.The present invention has a viscosity break ratio being effectively increased petroleum crude oil, and effectively reduces the advantages such as paraffin content in crude oil.
Description
Technical field
The present invention relates to a kind of thinner, be specifically related to the preparation method of petroleum crude oil thinner.
Background technology
In viscous crude, light constituent content is low, and asphalitine and gum level are higher, and straight-chain hydrocarbons content is few, thus causes major part thick
Oil has high viscosity and highdensity characteristic, exploits and transport extremely difficult.At present, commonly use both at home and abroad during thickened oil recovery
Fall sticking method have heating, mixing light oil method, upgrading fall glutinous and the glutinous method of chemical agent fall.Breast is added when thick oil steam drive
Changing visbreaking agent, be a kind of newer the Technology of Heavy Oil Recovery, the key component of reducing viscosity by emulsification agent is surfactant, by reducing oil
Water interfacial tension, makes the viscous crude in stratum be changed into the emulsified state with water as foreign minister from water in oil emulsified state, makes viscous crude
Viscosity is greatly lowered, and recovery ratio significantly improves.
The viscosity break ratio of existing petroleum crude oil thinner is undesirable, especially on paraffin content without impact, causes exploiting being difficult to
Problem.
Summary of the invention
