Abstract
The invention provides a paraffin remover and a preparation method thereof. The paraffin remover comprises the following components (in percentage by weight): 15%-25% of alcohol ether, 7%-12% of fatty alcohol-polyoxyethylene ether, 0.15%-0.25% of alkali, 13%-15% of antifreezing fluids, 5%-10% of ethylene glycol and 30%-40% of emulsifying agents, wherein the emulsifying agent is a mixture of oleic acid, linoleic acid, composite vinegar of resin and triethanolamine, the antifreezing fluids comprise propylene glycol butyl ether acetate and ethylene glycol butyl ether acetate, and the alkali is any one of sodium hydroxide or potassium hydroxide. The preparation method of the paraffin remover comprises the following steps: adding the alkali to the fatty alcohol-polyoxyethylene ether to generate a surface active agent; adding the surface active agent to alcohol ether, and stirring under the condition of normal temperature and pressure; and then sequentially adding the antifreezing fluids, the ethylene glycol and the emulsifying agents so as to obtain the paraffin remover. The paraffin remover provided by the invention has the advantages of safety in use, low possibility in ignition and low solidifying point and meets the requirement for usage under the condition of extreme cold.
Description
Technical field
The invention belongs to oilfield chemistry Application Areas, be specifically related to a kind of paraffin remover and preparation method thereof.
Background technology
Wax is usual under formation conditions to be existed with liquid state.But in recovery process, along with temperature and pressure decline and light component are constantly overflowed, the wax in crude oil can be separated out gradually and is deposited on around the borehole wall and in production casing, damages oil bearing reservoir, the normal production in restriction oil field.According to the literature, China's major part exploitation crude oil is rich in wax, all more than 20%, some even high 40%. therefore, paraffin removal from oil well is the very important technical measures of of ensureing that waxy crude oil normally produces.
The paraffin removal from oil well technology that oil field is conventional, mainly contains mechanical paraffin removal technology, heating power Paraffin Removal technology, surface energy anti-wax technique, chemical agent Paraffin Removal technology, magnetic paraffin control technology and the large class of Microorganism Wax Removal And Paraffin Inhibition 6.Carrying out Paraffin Removal with chemical agent to oil well is current field use more a kind of Paraffin Removal technology.Chemical paraffin removing and inhibitor has oily molten type, water-soluble and emulsion-type three kinds of liquid wax removing agents, and the advantage of oily molten type wax removing agent is: stronger to crude oil adaptability; Molten wax speed is fast, adds instant effect after oil well; Product zero pour is low, uses also very convenient in the winter time.Its shortcoming is: relative density is little, and very unsuitable to moisture high oil, burning-point is low, easily catches fire, and must have rigorous fire measure during use.The advantage relative density of water-soluble wax removing agent is comparatively large, better to high-water-cut oil-producing well effect; Use safety, without ignition hazard.Its shortcoming is that to add the oil well speed that takes effect slower; Although the zero pour of water based dewaxing agent can reach one 20 DEG C now, at the use in winter of severe cold, its mobility is very poor.Emulsion-type wax removing agent has the fireballing advantage of the molten wax of oily molten type wax removing agent, due to this wax removing agent, its foreign minister taking liquid is water, because of and as water-soluble wax removing agent use safety, not easily to catch fire and relative density is larger, but this wax removing agent prepare and storage time must stablize, simultaneously preparation and duration of service conditional request higher.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide and a kind ofly meet wax removal requirement simultaneously its preparation method paraffin remover that is simple, that be extensively suitable for, its specific embodiment is:
A kind of paraffin remover, its feature is being, its moiety (weight ratio) comprises alcohol ether 15 ~ 25%, fatty alcohol-polyoxyethylene ether 7 ~ 12%, alkali content 0.15 ~ 0.25%, deicing fluid 13 ~ 15%, ethylene glycol 5 ~ 10%, emulsifying agent 30 ~ 40%.
Further, described emulsifying agent is the Composite vinegar of oleic acid, linolic acid and resin and the mixture of trolamine.
Further, described deicing fluid is propandiol butyl ether and 2-Butoxyethyl acetate composition, and its weight ratio is 30% ~ 70%:70% ~ 30%.
Described alkali is any one in sodium hydroxide or potassium hydroxide.
A kind of preparation method of paraffin remover: alkali is joined fatty alcohol-polyoxyethylene ether and generate tensio-active agent, joined in alcohol ether and stirred at normal temperature and pressure conditions, stir 10 ~ 30min, stirring velocity 200 ~ 300r/min, then add deicing fluid, ethylene glycol, emulsifying agent successively.Obtain paraffin remover.
Advantage of the present invention is: form water external emulsion after molten for oil type wax removing agent being added water and emulsifying agent and stablizer, after this milk sap adds oil well, carry out breakdown of emulsion and discharge to have excellent dissolution performance to wax under bottom temperature.Because foreign minister is water, because of and as water-soluble wax removing agent use safety, not easily to catch fire and relative density is comparatively large, add the zero pour that deicing fluid and ethylene glycol can reduce paraffin remover, its paraffin remover can well be improved because freeze the non-serviceable difficulty brought.
