Description
Technical field
The invention belongs to fossil fuel production technique fields, and in particular to a kind of high efficiency heavy crude thinner and its preparation side
Method.
Background technique
Viscous crude stock number is about 25,000,000,000 tons or so, accounts for the 28% of the total oil in place of petroleum.With not turning off for conventional crude
It adopts, reserves and yield constantly decline, to meet the needs of industrial and agricultural production is growing to the energy, the development and production institute of viscous crude
The specific gravity accounted for will be increasing.The viscosity of viscous crude is up to 100mPas or more, and density is greater than 0.92g/cm3.For petroleum,
Solid hydrocarbons, the content of asphalitine and colloid and composition are the principal elements for determining its rheological characteristic.And viscous crude studies on asphaltene and colloid
Content is especially high, and they structure is complicated, molecular weight is big.
Viscous crude is a kind of multi-component homogeneous organic mixture of complexity, and colloid contains with asphalt content height, light components
Measure that low, straight chain hydrocarbon content is few, viscosity is high, fluid ability is poor, these features to viscous crude exploitation sum aggregate it is defeated bring it is huge tired
Difficulty, for example, viscosity of thickened oil is high, poor fluidity causes viscous crude filtrational resistance in oil reservoir big, prevent viscous crude from oil reservoir from flowing into
Exploitation of many technologies for viscous crude has now been developed to be difficult to exploit in shaft bottom, such as heating power viscosity reduction, ultrasonic thinning are micro-

It is viscous that height is required to reservoir condition.
Viscous crude is with other common thin oils main difference is that wherein containing more resin and asphalts, this is also viscous crude
The biggish principal element of viscosity.Colloid, asphaltene molecules are relative molecular mass maximum and the strongest component of polarity in viscous crude, are ground
Study carefully discovery, asphaltene molecules exist in the form of three-dimensional association networks in crude oil, form the very high aggregation of regularity.Glue
Matter Molecular Adsorption forms the transition zone between asphaltene particles and fluid oil, makes asphaltene particles on asphaltene aggregation body
It suspends in the oil, forms colloidal oil.Very big internal friction can be generated when the intermolecular generation relative displacement of crude oil, thus table
Reveal the high viscosity of crude oil.In addition, the colloid of high metal content viscous crude, metal (such as V, Ni etc.) 90% in asphalitine is with porphyrin
Compound form exists, and is combined together with coordinate bond, also results in asphaltene molecules to a certain extent and be gathered in one
It rises, so that the viscosity for causing high metal content viscous crude is bigger than the viscosity of common heavy oil, therefore, the viscous crude of high metal content
Viscosity reduction difficulty is bigger.
Existing viscosity reduction method, which mainly has, mixes dilute viscosity reduction, heating power viscosity reduction and chemical viscosity reduction.Mixing dilute viscosity reduction is to viscous crude
Middle a certain amount of thin oil of incorporation needs to consume a large amount of thin oil although this method effect is preferable to reduce the viscosity of viscous crude
Resource.Heating power viscosity reduction is the viscosity that viscous crude is reduced with the method for heating, but this method needs a large amount of energy consumption and efficiency
It is not high.Chemical viscosity reduction includes reducing viscosity by emulsifying and oil-soluble viscosity reduction --- and reducing viscosity by emulsifying, which refers to, utilizes water soluble surfactant active and original
Emulsion oil-in-water is formed between oil to achieve the purpose that reduce viscosity；Oil-soluble viscosity reduction is by utilizing pole in molecular structure
Property group and asphalitine, colloid interact, and destroy gum asphalt aggregation and space net structure, it is former to reach reduction
The purpose of oil viscosity.Existing chemical viscosity reduction technology is primarily present the inefficient problem of viscosity reduction, therefore develops a kind of viscosity reduction effect
The high heavy crude thinner of rate has broad prospects.
