Abstract
The present invention relates to the methods that one kind preparing choker living polymer heavy crude thinner by 1,2,3,5 four p-methyl benzenesulfonic acid mesoinositol, six alkane of Isosorbide-5-Nitrae diazacyclo and N, N dimethyl docosyl tertiary amine for primary raw material.1,2,3,5 four p-methyl benzenesulfonic acid mesoinositol and six alkane of Isosorbide-5-Nitrae diazacyclo of equivalent are carried out polymerisation by the present invention first, and then the N with twice, N dimethyl docosyl reactive tertiary amines prepare a kind of amphipathic polymer with special backbone structure again.The polymer has the ability for being significantly reduced asphalitine viscosity of thickened oil, and reliable preparation process provides a kind of preparation method of novel heavy crude thinner.
Description
Technical field
The invention belongs to oilfield oil extraction additive field, more particularly to one kind by 1,2,3,5- tetra- p-methyl benzenesulfonic acid mesoinositol,
Six alkane of Isosorbide-5-Nitrae-diazacyclo and N, N- dimethyl docosyl tertiary amine are the method that primary raw material prepares novel heavy crude thinner.
Background technology
In recent years, being continuously increased along with thickened oil recovery amount, the exploitation of extra-high viscosity viscous crude is to oil extraction and conveying
Extreme difficulties are brought, and the key of heavy oil development is to reduce viscosity of crude, improve its mobility.Although having in the prior art
Various thinners, but still lack thinner efficiently, stable to special heavy crude oil.
Viscosity of thickened oil is mostly derived from the stronger intermolecular interaction between its asphalitine, colloid equimolecular, reduces or eliminates drip
Active force between green matter and colloid equimolecular is the key that reduce its viscosity.Foreign molecules be embedded in asphalitine and colloid aggregation it
Between prevent its strength aggregation be reduce viscosity of thickened oil one of effective measures.
The active group of comb-shaped polymer molecule is distributed around its main chain surrounding, once embedded heavy oil asphalt matter and colloid are poly-
Collective can make heavy oil asphalt matter and colloid aggregation molecules align more unordered, greatly reduce asphalitine and colloid is intermolecular
Active force, reduce viscosity of thickened oil.
The present invention is with 1,2,3,5- tetra- p-methyl benzenesulfonic acid mesoinositol, six alkane of Isosorbide-5-Nitrae-diazacyclo and N, N- dimethyl 22
Alkyl tertiary amine is the viscosity that novel comb-shaped polymer heavy crude thinner prepared by primary raw material can significantly reduce special heavy crude oil.Its
Middle main chain because can be combined with the pitch of electronegativity, colloid molecule strength containing azacyclo-, to entire molecule insertion asphalitine and
Colloid aggregation plays the role of power-assisted；And hydrophobic side chain docosyl then prevents asphalitine and the intermolecular aggregation of colloid.
Invention content
The present invention is first gathered six alkane of Isosorbide-5-Nitrae-diazacyclo of 1,2,3,5- tetra- p-methyl benzenesulfonic acid mesoinositol and equivalent
Reaction is closed, then the N with twice, N- dimethyl docosyl reactive tertiary amines again, preparing a kind of having special backbone structure
Novel comb-type amphiprotic polymer.The polymer has the ability for being significantly reduced asphalitine viscosity of thickened oil, and reliable preparation process provides
A kind of preparation method of novel heavy crude thinner.
