Description
Technical field
The present invention relates to oil-field thick-oil well Produced Liquid viscosity reduction fungicide, belong to chemical reagent technical field.
Background technique
With the continuous exploitation of petroleum, petroleum reserves especially conventional crude reserves are constantly reduced on the earth.It is verifying
Petroleum resources in, viscous crude proportion is increasing, and the exploitation of viscous crude becomes more and more important.But since viscous crude is with special
High viscosity and high condensation point characteristic, all encounter some technical problems in the various aspects of development and application.And viscous crude contains
More colloid, asphalitine, they cause mobility of the crude oil in reservoir and pit shaft to be deteriorated, mining belt are given to carry out many inconvenience.
With the development of new and high technology, oil recovery, storage and transportation, refining technology be also constantly progressive, propose chemical viscosity reduction technology be at present most
One of potentiality, most promising viscosity reducing process.And when oil extraction, a large amount of bacterium can be bred in pipeline, is attached to pipeline
On, it can not only corrode equipment, block stratum when can also generate a large amount of hydrogen sulfide and re-injection.
Summary of the invention
The present invention in order to when overcoming high viscosity of thickened oil high, extraction complex process, cost of winning, exploitation bacteria breed etc. ask
Topic, the present invention provide a kind of heavy oil wells Produced Liquid viscosity reduction fungicide, and the medicament prepared is real by Q/SHCG65-2013 standard
It tests, viscosity of thickened oil can be effectively reduced；By Q/SY 49-2010 standard test, the bacterium in Produced Liquid can be effectively killed.
Thus the technical solution adopted by the present invention is that: 15-30 parts of polyisobutylene butanedioic anhydride, 4-8 parts of triethanolamine, laurel
20-30 parts of acyl propyl dimethyl tertiary amine, 1,3- bis- 10-20 parts of chloro- 2- propyl alcohol, octadecyldimethyl second base Benzyl ammonium chloride
10-20 parts, 15-30 parts of methanol.
It is a kind of specific the preparation method comprises the following steps:
A certain amount of each monomer first is weighed by feed ratio, polyisobutylene butanedioic anhydride is first placed in sealable reaction vessel
In, under nitrogen protection, stirring is warming up to 120-140 DEG C, triethanolamine is added dropwise, lauroyl third is added after reaction 3-4 hours
Base dimethyl tertiary amine is added dropwise, 1,3- bis- chloro- 2- propyl alcohol after reaction 3-4 hours, after reaction 4-6 hours, cools to 40-50 DEG C and adds
Enter octadecyldimethyl Yi Ji Benzyl ammonium chloride, methanol continues to be stirred to react 2-3 hours, and thinner finished product.
Novelty of the invention:
1. the present invention uses the reactant of polyisobutylene butanedioic anhydride, preferable to crude oil pitch dispersion effect, can effectively reduce
The viscosity of high pitch viscous crude plays a key effect to the viscosity reduction of high pitch viscous crude.
2. a kind of heavy oil wells Produced Liquid viscosity reduction fungicide of the invention, using cationic surfactant, when in use not
It is only capable of reducing the viscosity of viscous crude, while the bacterium in Produced Liquid can also be killed, a medicine is dual-purpose.
The present invention has the beneficial effects that
1, each low raw-material cost used in the present invention, and will not cause to corrode to the refining equipment in subsequent, save at
This, improves the utilization rate of equipment.
2, the technological process of production is simple, and operating method is easy, and automatic continuous production may be implemented, and mechanization degree is high,
It is suitable for promotion and popularization and industrialized production.
3, a kind of heavy oil wells Produced Liquid viscosity reduction fungicide of the invention, using cationic surfactant, when in use not
The viscosity of viscous crude can be reduced, while the bacterium in Produced Liquid can also be killed, a medicine is dual-purpose, saves making for oil field rear end fungicide
With economic benefit is obvious.
