Description
Technical field
The present invention relates to oilfield exploitation technical fields, are especially adapted for use in the viscous crude dispersion oil recovery auxiliary agent of offshore oilfield.
Background technology
Viscous crude（Also known as mink cell focus）Accounting is very big in petroleum reserves, and China is more so.Viscous crude gives filled drive since viscosity is big
Oil, well head extracting, pipeline all bring many difficulties.Difficult bigger of the offshore oil production than land oil recovery.Why viscous crude glues
Degree is big, is because viscous crude contains more long-chain hydro carbons（Heavy oil）, proportion, adiabatic condensation temperature are higher than light oil, and contain colloid substances
Matter, asphalitine are more, are easy caking, increase flow resistance.When using with water drive oil, salinity is high, also results in flow difficulties.It is necessary
Viscosity reduction Drag reduction devices are taken, could normally be produced.
The method of existing frequently-used viscosity reduction drag reduction has：1, heating：Using electrical heating, steam heating etc. makes Produced Liquid exist
It more than set point extracts, conveys, this can expend a large amount of energy.2, addition light oil is let down method：During heavy crude producing, add
Add the light-end products that carbochain is short（Such as diesel oil）, to keep viscous crude thinning, viscosity is reduced, more light oil, work need to be added in this method
Skill is complicated, need to increase the facilities such as pipeline, pump, cost is high.3, chemical viscosity reduction agent is added：Change Produced Liquid and emulsify type, improves
Its mobility has the oil-soluble surfactant of addition, water-soluble surfactant two major classes, but emulsion process increases to Produced Liquid
The difficulty and workload of demulsification are added.
Invention content
The present invention is formulated reasonable and practical, economizing on energy and electricity in view of the above problems, providing, and the apparent novel oil production of viscosity reducing effect helps
Agent.
What the object of the invention was achieved through the following technical solutions：In viscous crude production, oil water mixture, in Water-In-Oil
Emulsion state, its particle of Water-In-Oil be oil outside, including water, oily viscosity is high, so the viscosity of well liquid is high, flow resistance is big,
It is added auxiliary agent of the present invention, water-in-oil emulsion is demulsified reverse phase, becomes oil-in-water emulsion, and handle is adhered to pipeline, on sucker rod surface
Sticky crude oil stripped down by the effect of surfactant, water base lubricating film is formed between pipeline and liquid stream,
To reduce flow resistance, the viscous crude for being particularly suitable for offshore oilfield decomposes.
The auxiliary formula is as follows by 100% mass share：Sodium heavy alkyl benzene sulfonate 18~30%, sulfobetaines 12~
25%, fatty alcohol polyoxyethylene ether 6~12%, cocoanut fatty acid diethanolamide 10~15%, sulfonate type imidazoline quaternary ammonium salt
3%, sorbierite 8%, remaining ingredient are deionized water.
Beneficial effects of the present invention：（One）, formula it is reasonable and practical, viscosity reducing effect is apparent；（Two）, do not need electrical heating, save
The about energy；（Three）, it is cost-effective, it is time saving and energy saving, improve work efficiency and economic benefit.
Specific implementation mode
By formula rate, all the components are mixed evenly.Powder performance is as follows：Pale yellow transparent uniform liquid, nothing
Suspended matter, no precipitation, not stratified, good fluidity is soluble easily in water, is in uniform liquid after being mixed with water；PH value 6~9；Flash-point ＞
100℃；＜ -25 DEG C of condensation point.
When medicament uses concentration 3 ‰, viscosity break ratio ＞ 96%；Oil water interfacial tension ＜ 9*10-3mN/m；Drag reducing efficiency ＞ 80%；
Hang cup test：1% medicament aqueous solution is prepared, oil sample is mixed with institute dose out powders aqueous solution in beaker, oil-water ratio 7:3,
Stirring, is poured out, no extension cup phenomenon.
It is tested on well, carries out well head medicine-adding experiment in Shengli Oil Field offshore oil production factory CB248A-5, CB4D well, go out by oil well
This medicament is added in about the 3 ‰ of liquid, and viscosity reducing effect is apparent, and viscosity break ratio is 98% or more.
Electrical heating is saved during thickened oil recovery, power savings are apparent.
