Abstract
A high-efficiency pour point depressant for thermal recovery process comprises (1) biphenyl, polycyclic aromatic hydrocarbons or polycyclic aromatic hydrocarbon derivatives free of chlorine and sulfur elements; (2) liquid petroleum products containing arene larger than 5%, petroleum resin in liquid state at normal temperature or natural hydrocarbon aggregates in particle state at normal temperature; (3) surfactant; (4) fusel oil; (5) alcohol ethers having a closed cup flash point larger than 20 DEG C; and (6) oil-soluble or water-soluble polymers respectively having a nonpolar section eutectic with paraffin molecule and a polar section for twisting crystal form of wax crystal on a main chain and/or a branch chain. The high-efficiency pour point depressant of the invention performs all functions of both water-base pour point depressant and oil-base pour point depressant, and can efficiently assist the prior various thermal recovery processes in exploring high pour-point oil and heavy oil reservoirs, with the advantages of greatly reduced exploitation cost, prolonged production cycle of the oil well, increased output of the oil well, increased ultimate recovery of the oil reservoir, as well as significant economic benefit.
Description
Technical field
The present invention relates to a kind of pour point depressant that is used for oil production, especially a kind of high highly effective pour depressant that coagulates oil, viscous crude of heating exploitation that is used for.
Background technology
At present, thermodynamic oil extraction process is mainly used in high coagulate oil, viscous oil recovery, generally uses pour point depressant as householder method.Existing such pour point depressant is divided into water base pour point depressant and oil base pour point depressant two classes usually, and wherein water base pour point depressant specifically is divided into water-soluble pour point depressant, emulsion oil-in-water pour point depressant again; The oil base pour point depressant specifically is divided into oil soluble pour point depressant, organic solvent type pour point depressant again.
Water-soluble pour point depressant mainly is made up of tensio-active agent and water, is used for thermodynamic oil extraction process and has following defective: the one, and it mainly utilizes emulsification principle pour point depression, directly dissolved bitumen matter, colloid, wax crystalline substance, pour point depression is limited in one's ability; The 2nd, after injecting oil reservoir, oil well is difficult to be diffused into automatically crude oil; The 3rd, when the oil reservoir crude oil water containing is low, there are not effect or effect opposite.
The emulsion oil-in-water pour point depressant mainly is made up of tensio-active agent, water and organic solvent etc., be used for thermodynamic oil extraction process and have following defective: the one, it mainly utilizes emulsification principle pour point depression, directly dissolving, broken bituminous matter, colloid, wax-crystal structure are limited in one's ability, and pour point depression is limited in one's ability; The 2nd, after injecting oil reservoir, oil well is difficult to be diffused into automatically crude oil; The 3rd, when the oil reservoir crude oil water containing is low, there are not effect or effect opposite; The 4th, O/w emulsion layering immediately under the high temperature fluid heating can't realize that collaborative companion annotates.
The oil soluble pour point depressant mainly is made up of oil-soluble polymers, organic solvent etc., there is following defective: the one, though the oil soluble pour point depressant can suppress or dispersing wax crystalline substance, colloid piece, bituminous matter layer, but can't make it reach true sol particle granularity, pour-viscosity reduction is limited in one's ability; The 2nd, oil soluble pour point depressant flash-point is lower, annotates with the high temperature fluid companion to have safety problem; The 3rd, the oil soluble pour point depressant is with strong points, and the shaker test workload is big; The 4th, can't solve emulsified particle blockage problem in the oil reservoir; The 5th, there is ageing problem, promptly its pour-viscosity reduction ability prolongs in time and constantly reduces; The 6th, the cost height is difficult to heavy dose of application the in thermodynamic oil extraction process.
The organic solvent type pour point depressant mainly is by hydrocarbon composition, has following defective: the one, and the organic solvent type pour point depressant is limited to wax crystalline substance, colloid dissolving power, and to stratiform bituminous matter dissolving power extreme difference, pour point depression is limited in one's ability; The 2nd, organic solvent type pour point depressant flash-point is lower, annotates with the high temperature fluid companion to have safety problem; The 3rd, the organic solvent type pour point depressant is difficult to suppress the geometrical dimension of bituminous matter, wax-crystal structure, also can't solve emulsified particle blockage problem in the oil reservoir; The 4th, there is ageing problem, promptly its pour point depression ability prolongs in time and constantly reduces; The 5th, add-on is too big, causes cost of winning significantly to improve, and is difficult to practicability in thermodynamic oil extraction process.
In a word, present pour point depressant mostly has certain defective, and net effect is not fine in thermodynamic oil extraction process.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of highly effective pour depressant that is used for thermodynamic oil extraction process.This highly effective pour depressant has the repertoire of water base pour point depressant and oil base pour point depressant concurrently, can use or common companion's notes with high temperature fluid is collaborative, make bituminous matter, colloid, wax-crystal structure micritization, effectively solve oil reservoir emulsification blockage problem, effectively solve the ageing problem of medicament simultaneously; Advantages such as in general, it is strong that this pour point depressant has suitability, and the pour point depression ability is strong, and is safe and reliable, and field conduct is simple, and consumption is few; Can effectively assist high oil, the heavy crude reservoir of coagulating of existing various heating exploitation technology exploitation, significantly reduce cost of winning, prolong the oil well production cycle, increase oil well output, improve the oil reservoir ultimate recovery factor.
