Description

A kind of compound anti-freezing type emulsion wax removing agent of high-efficiency environment friendly
Technical field:
The present invention relates to oil well Chemical Paraffin Removal & Control Techniques field, especially a kind of compound anti-freezing type emulsion wax removing agent of high-efficiency environment friendly.
Background technology:
For extremely frigid zones oil field, the former innage content of wax, high condensation point, enter development late stage, and producing well wax deposition is serious, and oil well hot washing period is short, and impact is produced.The on-the-spot wax removing agent using is mainly traditional oil-based solvent paraffin remover and water base paraffin inhibitor chemical at present.High but the irritant smell of oil-based solvent paraffin remover wax removal efficiency, density is little, volatile, inflammable and explosive toxicity is large, poor stability, in high-water-cut oil-producing well, effect is poor, if polymer flooding screw pump oil production well life-time service solvent-borne type paraffin remover paraffin removal, can cause pump stator material dilatational strain, damage; Water base paraffin inhibitor chemical toxicity is little, but it take tensio-active agent as main, and because tensio-active agent price is high, working concentration is large, and wax control result is good but wax removal efficiency is very low, and the extent of spreading amd application is limited; Due to organic solvent and tensio-active agent, price is constantly soaring in recent years, causes this type of wax removing agent settlement price and cost to hang upside down, and adulterates and occurs repeatedly, dragons and fishes jumbled together for quality product, affects the paraffin removal of production well, and heat is washed the frequency and improved, cause hot clean-up well task heavy, also affect output.
Summary of the invention:
The invention reside in and overcome the problem existing in background technology, and a kind of compound anti-freezing type emulsion wax removing agent of high-efficiency environment friendly is provided.The compound anti-freezing type emulsion wax removing agent of this high-efficiency environment friendly, effectively wax removal, wax control, reach and reduce oil well operating load, extends purge period, the low wax removal in winter that is specially adapted to extremely frigid zones of condensation point.
The present invention solves its problem and can reach by following technical solution: the compound anti-freezing type emulsion wax removing agent of this high-efficiency environment friendly, comprise host A agent system, assistant agent B agent system, its component and proportioning are as follows by weight percentage: host A agent system: 1-3% oil soluble macromolecule polymkeric substance, 40-60% aromatic hydrocarbons organic solvent, 10-20% low-carbon alcohol, 3-10% compound emulsifying agent, 10-30% water; Assistant agent B agent system: 7-15% acids ionogen, 85-93% water; Host A agent system: assistant agent B agent system is 100:(0.8-1.2).
Described oil soluble macromolecule polymkeric substance is alkylnaphthalene, polymethacrylate, EVA or SMA; Aromatic hydrocarbons organic solvent is benzene, dimethylbenzene or toluene; Low-carbon alcohol is methyl alcohol, ethanol, ethylene glycol or butanols; Described compound emulsifying agent is negatively charged ion surfactant and polymeric carboxylic, and negatively charged ion surfactant and polymeric carboxylic ratio are 1.7: 1; Described negatively charged ion surfactant is polymer fatty acid potassium, sodium, ammonium salt or triethanolamine salt, and polymeric carboxylic is C 16-20unsaturated olefin acid; Described acids ionogen is hydrochloric acid, formic acid, acetic acid or oxalic acid.
The compound anti-freezing type emulsion wax removing agent of this high-efficiency environment friendly, adopt emulsifying technology, oil phase using oil soluble high molecular polymer, organic solvent as milk sap, with complexed surfactant as emulsifying agent, be aided with mutual solvent and water base clear wax control composition, make stabilized oil-in-water emulsion as host A agent, the B agent of take activates breakdown of emulsion when assistant agent is used.Have long-term storage stable performance under surface condition, activate that breakdown of emulsion produces oil base in oil well and water base paraffin remover carries out wax removal during use, wax removal is effective, and has certain washing oil adhesion reducing and wax preventing effect.The features such as nonflammable explosive, low toxicity, efficient and cost are low.This product overcomes poor or slow, the shortcoming that falls flat of breakdown of emulsion while using of ordinary emulsion paraffin remover surface stability, the low wax removal in winter that is specially adapted to extremely frigid zones of condensation point.
Owing to there being naturally occurring emulsifying agent in crude oil, for the crude oil of moisture 25.98%-74.02%, under pit shaft turbulent flow and mechanical effect, oil and water form W/O milk sap, and viscosity of crude promotes greatly, with the cooling of pressure drop and lifting process, wax partial crystallization goes out, coalescent adhesion deposition is on underground equipment and tube wall.Emulsion paraffin remover A, after B agent is compound, enter in oil well oil jacket annular space, fast emulsion breaking, isolate organic solvent and water base paraffin remover, dilute with water several times during due to mixed phase and use, density is large compared with the molten paraffin remover of traditional oils, enter the following speed of pit shaft liquid level fast, the quick dissolving of organic solvent has been deposited on the wax on tube wall, complexed surfactant in water base paraffin remover not only contributes to wax removal simultaneously, and its part activity is greater than the surfactivity of naturally occurring emulsifying agent in crude oil, make system there is lower oil water interfacial tension, form O/w emulsion, change Wettability of Solid Surface, wetting form layers polarity moisture film on tubing wall, there is certain washing oil adhesion reducing and wax preventing effect.
The present invention compares and can have following beneficial effect with above-mentioned background technology: the compound anti-freezing type emulsion wax removing agent of this high-efficiency environment friendly, A agent is that oil soluble macromolecule polymkeric substance, aromatic hydrocarbons organic solvent, water base paraffin remover, complexed surfactant are the stable oil/water emulsions that emulsifying agent forms, B agent is breakdown of emulsion promotor, is a kind of inorganic electrolyte solution.This compound anti-freezing type emulsion wax removing agent A, B agent are deposited separately, during on-the-spot use in A:B=100:(0.8-1.2) add oil well oil jacket annular space after ratio is composite.Assistant agent B agent system is as breakdown of emulsion activator, and during use, host A agent activates breakdown of emulsion through B agent, produces oil base and water base paraffin remover carries out wax removal in oil well, and wax removal is effective, and has certain washing oil adhesion reducing and wax preventing effect.The features such as nonflammable explosive, low toxicity, efficient and cost are low.With traditional medicament contrast, a little less than anti-freeze type emulsion wax removing agent volatility, and not containing organochlorine and organosulfur, Environmental Safety, condensation point is high, freeze-proof good, density adds greatly and after dilute with water, easily arrive under pit shaft oil jacket annulus liquid level, rapid-action, host A agent activates through assistant agent B, fast emulsion breaking, make oil base, water base sharp separation, molten wax wax control speed is fast, reach the dual purpose of not only wax removal but also wax control, overcome the effect unicity of existing medicament, no matter be to being deposited on the solidifying oily wax dirt of tube wall, or to pit shaft wet oil, the solidifying oily wall built-up amount of its viscosity reduction and reduction is effective, the solidifying oily wall built-up amount range of decrease (being inhibiting rate for wax precipitation) reaches more than 64%, the brilliant paraffin inhibitor chemical inhibiting rate for wax precipitation of oil base wax requiring higher than existing standard is greater than 30%, aqueous based surfactant type paraffin inhibitor chemical inhibiting rate for wax precipitation is greater than 50%.
