Abstract
The invention relates to an oil well neutral supramolecular care exploitation assistant, belonging to the technical field of fine chemical engineering. The oil well neutral supramolecular care exploitation assistant comprises the following components in percentage by weight: 10-15% of acrylic acid, 15-21% of polyepoxysuccinic acid, 11-15% of hydroxy ethidene bis phosphoric acid, 4.5-7% of coconut diethanol amide, 2-3% of dodecyldimethylbenzyl ammonium bromide, 1-2% of fatty alcohol polyethenoxy ether and the balance of water. The oil well neutral supramolecular care exploitation assistant is simple to use, and can clean oil well dirt on line within 36-48 hours. The formed supramolecular film can prevent scales, resist corrosion and prolong the service life of the oil well; and the produced fluid of on-line cleaning can also be used for cleaning and caring oil piping. The care exploitation assistant has the functions of dispersing and emulsifying thick oil, driving the oil body to flow and assisting in exploitation.
Description
Technical field
The present invention relates to a kind of oil well neutrality maintenance adjuvant, belong to technical field of fine.
Background technology
In oilfield process, mining system and collection transmission pipe network fouling corrosion problem govern oil field development always. The dirt formed is mainly incrustation scale and wax deposition, also has a large amount of rust deposite, and fouling can substantially reduce flow and yield, serious even blocking, holddown. Except conventional chemical attack, it is often more important that fouling causes that caliber attenuates, flow velocity increases, and increases the weight of the silt that the sinks erosion rate to duct bottom, causes that pipe network is revealed. So, for oilfield tube network and well system, fouling is the first harm, directly affects recovery ratio and economic benefit, is a major challenge of facing of domestic many oil fields.
At present, for the scale problems in oilfield process, mainly overcome from two approach: one, take certain measure prevent and delay fouling (include the physical oil production technology such as ultrasound wave, electromagnetic method and add the chemical scale inhibition technology such as antisludging agent) as far as possible; Its two, the dirt formed is purged the physics scale removal such as chemical cleaning, high-pressure water jet and mechanical descaling's technology such as (include acid) eccysis. But, various antiscale, descalling technique have certain limitation, the still not thorough efficient solution of scale problems, stifled well, bit freezing, and pipeline stopping state often occurs; More there is no a kind of medicament being capable of the comprehensive functions such as scale removal, antiscale, pipe network equipment maintenance.
Summary of the invention
It is an object of the invention to provide a kind of oil well neutrality supermolecule maintenance adjuvant. Its metal surface acting on oil field equipment by Supramolecular self assembly forms one layer of Supermolecular film, simultaneously, due to Brownian movement and the effect of vibration of agent molecule, by the soil dispersion such as the various rust deposites of metal surface, grease, dirt to solution, thus reaching scale removal effect. The film formed in metal surface is fine and close, smooth, has and is similar to the anticorrosion of Folium Nelumbinis, anti-pollution function, can avoid the device damage because fouling and corrosion cause, effectively realize the maintenance of oilfield exploitation gathering system equipment and pipe network.
The present invention realizes above-mentioned purpose and the technical scheme is that oil well neutrality supermolecule maintenance adjuvant, including following components in percentage by weight: acrylic acid 10%��15%, poly-epoxy succinic acid 15%��21%, 1-hydroxy ethylidene-1,1-diphosphonic acid 11%��15%, cocoanut fatty acid diethanolamide 4.5%��7%, dodecyl dimethyl benzyl ammonium bromide 2%��3%, fatty alcohol-polyoxyethylene ether 1%��2%, surplus is water.
The oil well neutrality supermolecule maintenance adjuvant of the present invention is prepared from by the following method: by each component according to, after proportioning mix homogeneously, regulating pH to neutral with sodium hydroxide.
The oil well neutrality supermolecule maintenance adjuvant of the present invention is easy to use, it is possible to on-line cleaning oil well dirt, the time only needs 36��48 hours. In order to save medicament, it is also possible to discontinuous shuts down soaking and washing. Act well tool need not be risen or propose tubing string, when water saving, fuel-economizing, joint work, joint, oil country tubular good, sucker rod etc. is corrosion-free, to the encapsulants such as rubber and instrument not damaged, it is possible to the abluent that secure replacement is traditional. The all right scale inhibition anticorrosion of the Supermolecular film formed, extends the oil well life-span, and the Produced Liquid of on-line cleaning can also clean nursing flow circuit. Medicament also has dispersion, emulsifying viscous crude, drives oil body flowing and helps the effect of adopting.
The oil well neutrality supermolecule maintenance adjuvant of the present invention is colourless to light yellow transparent liquid, in neutrality, nontoxic non-corrosiveness.
