Abstract
The defeated viscosity reduction corrosion inhibiter of thickened oil recovery collection is used for the present invention provides a kind of, by weight percentage, including：Low pole polymer 5% 8.5%, alkylaryl sulfonates 0.5% 1.5%, imidazolidine derivatives 1% 2%, organic solvent 88% 93.5%；Wherein, the sum of each component weight of the viscosity reduction corrosion inhibiter is 100%.The present invention also provides viscosity reduction corrosion inhibiter preparation method, including：Low pole polymer, alkylaryl sulfonates, imidazolidine derivatives and organic solvent are added in reaction kettle, uniform stirring is sufficiently mixed each component；Viscosity reduction corrosion inhibiter is obtained with postcooling.The viscosity reduction corrosion inhibiter of the present invention has both viscosity reduction, inhibition effect, can obviously reduce the viscosity of viscous crude, slows down corrosive pipeline.
Description
Technical field
The invention belongs to field of oilfield exploitation, in particular it relates to which a kind of viscosity reduction defeated for thickened oil recovery collection delays
Lose agent and preparation method thereof.
Background technology
Viscous crude refers to crude oil of the viscosity more than 50mPa.s under reservoir temperature, can be further divided into viscous crude according to viscosity
Common heavy oil (50~10000mPa.s), special thick oil (10000~50000mPa.s), super-viscous oil (more than 50000mPa.s).
In world wide, heavy oil reserves are suitable with ordinary crude oils, and China's viscous crude accounts for 56% of crude oil reserve or so, are a kind of important money
Source.Since resin and asphalt content is high in viscous crude, viscosity is big, poor fluidity, causes that exploitation difficulty is big, recovery ratio is relatively low.It is super
Deep-layer heavy crude refers to that depth of reservoirs is more than the heavy crude reservoir of 4000m, because well depth oil is thick, the exploitation of such petroleum resources is always
Global problem, cost of winning is high, and economic benefit is low, while the corruption such as hydrogen sulfide, carbon dioxide are often accompanied by such petroleum resources
Corrosion gas, output water salinity is high, in addition bottom hole temperature (BHT) is high, oil/gas well tubing string, the defeated circuit of collection all suffer from serious corrosion
Problem.
It is a kind of widely used thickened oil recovery technique to mix dilute viscosity reduction.This technique is with distillate, dilute crude oil or other has
Solvent is diluent, and injection pit shaft is mixed with viscous crude, its viscosity is greatly reduced, mobility raising, reaches minable journey
Degree.According to existing research, viscosity of crude usually could be exploited and be conveyed in below 4000mPas.It is super thick for some
Oil, special thick oil, such as Tahe Heavy Crude, viscosity in more than 50000mPas, need addition Macrodilution agent that could reach mostly
The viscosity required to normal production.The dosage of diluent is to determine an important indicator of thickened oil recovery economy.To reduce
The development of oil-soluble viscosity reducer for the purpose of diluent dosage is carried out extensively, but is only limitted to desk research and field test mostly
Stage.Demand of industrial production oil-soluble viscosity reducer has higher replacement efficiency, adds in a small amount of thinner with regard to alternative a large amount of
Diluent, the oil-soluble viscosity reducer having been reported can not mostly be met the requirements.
Solving the thinking of oil field etching problem at present mainly has two, and one changes oil/gas well tubing string material and makes its corrosion resistant
Erosion or inside lining anti-corrosive tubing；Second is that use corrosion inhibiter.In actual application, corrosion-resistant tubing is of high cost, still will appear
Spot corrosion, pitting corrosion, intensity just have been unable to meet production needs in safe service life.Though corrosion inhibiter is commonly used, in height
In salinity environment again high temperature resistance corrosion inhibiter still phoenix feathers and unicorn horns.
Therefore, production requirement can normally be met in order to reduce the intensity of diluent dosage, guarantee oil well pipe, it is necessary to
Invent it is a kind of have both viscosity reduction, inhibition effect chemical agent composition system.
Invention content
The goal of the invention of the present invention is in view of the drawbacks of the prior art, to provide a kind of viscosity reduction defeated for thickened oil recovery collection and delay
Lose agent and preparation method thereof.
On the one hand, the present invention provides a kind of viscosity reduction corrosion inhibiter defeated for thickened oil recovery collection, by weight percentage, should
Viscosity reduction corrosion inhibiter includes：Low pole polymer 5%-8.5%, alkylaryl sulfonates 0.5%-1.5%, imidazolidine derivatives
1%-2%, organic solvent 88%-93.5%；Wherein, the sum of each component weight of the viscosity reduction corrosion inhibiter is 100%.
Aforementioned viscosity reduction corrosion inhibiter, the low pole polymer are that methacrylate-styrene-propene amide ternary is total to
Polymers and/or, maleic anhydride-vinyl acetate-acrylic acrylate copolymer.
Aforementioned viscosity reduction corrosion inhibiter, the alkylaryl sulfonates are double alkylaryl sulphurs of logical formula (I) or logical formula (II)
