Detailed Description Of The Invention
The present invention relates to the New Regenerated method of used halide fluids. In general, used halide fluids such as calcium or Zinc salt water is from commercial run such as oil gas drilling, agriculture chemistry method, metal plating or water treatment facilities Reclaim. The halide that reclaims contains solvable and soluble impurity usually, may be diluted, so that halogen Compound density and electrolyte concentration can not satisfy the needs of continuous industry operation.
For convenience of explanation, describe below with reference to the salt solution liquid that uses in the oil gas drilling, this is not Limit protection scope of the present invention. The transparent salt-water liquid that uses in dark oil well and the natural gas well knows from experience because behaviour Do the increase of water concentration in the system and be diluted. In addition, they may be by such as metal cation, hydro carbons Material is such as the contaminating impurity of oil and organic polymer, solid, mud and sandstone. As a result, salt solution liquid Oeverall quality descends; Specifically, its density descends, and actual crystallization temperature (TCT) changes to and do not meet The degree of product specification. The production cost costliness of salt solution liquid. In addition, because exist big in the salt solution liquid Measure poisonous chloride, bromide and zinc, so the processing of transparent effluent brine liquid is very expensive. With Method of the present invention is carried out with controlled manner the regeneration of waste liquid, so regenerate brine can be economically Be recycled in the system.
With reference to figure 1, in an embodiment of actual motion of the present invention, halogenide waste liquid 60, as drilling fluid, its density can be greater than water-mass density, as 9.0lbs/gal, but its density can be even as big as not carrying out drilling operation, particularly in the well of dark or elevated pressures.In order to be used for the oil well operation, halogenide liquid has drilling operation and/or well is pressed required specific density.Transparent brinish density as completion, maintenance and drilling fluid is higher than water-mass density, is 8.3lbs/gal, generally is about 11.4lbs/gal-16lbs/gal, even may be high to 23.0lbs/gal, and this depends on brinish target purposes.The general ionogen that uses basic metal, alkaline-earth metal and base metal in the composition of these salt solution liquid is generally selected according to its ability that improves drilling fluid density.In the method for the invention, the density of waste liquid of drilling returns to the essential density of oil well operation, thereby liquid can be regenerated to its useful state.In fact the present invention can also regulate the actual Tc (TCT) of liquid.TCT is the function of density.In the oil and gas operation, the recovery well operator will check the specification of the interior electrolytical TCT of liquid of use.These throw outs will cause negative impact to liquid properties required in the oil and gas industry.
Accompanying drawing illustrates the waste liquid 60 of sending into reactor 10 with pipeline.The composition of halogenide waste liquid 60 and density have determined the parameter of the inventive method.The information of liquid composition and aspect of performance, that is, the impurity of the ionogen of existence, initial pH, density and existence is for determining that technology and chemical substance that this method is used are very crucial.The ionogen that exists in the halogenide waste liquid 60 that reclaims can comprise alkali, alkaline-earth metal or base-metal salt.These salt can be selected from following salt: sodium-chlor, calcium chloride, zinc chloride, Sodium Bromide, Calcium Bromide, zinc bromide or its mixture.Also can consider strontium chloride, strontium bromide, cupric chloride, cupric bromide, nickelous chloride, nickelous bromide, aluminum chloride or aluminum bromide.
Salt aqueous waste solution 60 generally includes any mixture of these metal-salts such as calcium chloride, Calcium Bromide and/or zinc bromide.In one embodiment, the metal that exists in the halogenide waste liquid of recovery can comprise zinc, copper, cobalt, cadmium, nickel, potassium, caesium, lithium, barium, magnesium, aluminium, manganese, chromium or its combination.The halide ions that exists can comprise above-mentioned bromide or muriate, but iodide ion also within the scope of the invention.These different electrolytical hybrid modes depend on required desired density of specific salt solution liquid and Tc to a great extent.Can obtain the transparent salt solution liquid of higher density with two or three component electrolyte mixtures.When mixing the transparent salt solution liquid of higher density, to compare with the chloride electrolyte that density is lower, the bromide ionogen has higher adaptability.In addition, the stability and the TCT of mixing finished product also depend on the ratio of various ionogen in composition.For example, the salt solution liquid that calcium chloride concentration is high may be settled out carbonate or the vitriol in the local water that often is present in oil or gasser.On the other hand, zinc bromide salt solution can be used for providing high-density, and the salt solution liquid of no calcium is because the acidity of zine ion and can not be settled out negatively charged ion as carbonate and vitriol.Can also regulate the TCT of liquid with such zinc bromide salt solution.
In regeneration halogenide waste liquid process, can regulate salt solution density of liquid and TCT by the electrolyte concentration that changes in the solution.Parameters such as the acidity of necessary this method of adjusting, temperature in regenerative process are to finish the electrolytical mixing that exists.Should analyze and estimate the solids content of halogenide waste liquid.Preferably, in reactor 10, before to liquid treatment, remove solid with solid-liquid separation method well known in the art.Very high solids content will make unwanted foreign matter content rising in the product in the raw material of reactor 10, also influence other performance of liquid.
In a method of regeneration halogenide waste liquid, the initial halogenide waste liquid 60 of sending into reactor 10 with pipeline is a liquid diluted in the oil well operation process, can comprise solvable and soluble impurity, as metallic cation, hydro carbons, polymkeric substance, suspended solids, drilling cuttings and sand or chad.Because diluted when water in the oil well contacts, so the density of these waste liquids generally is lower than the required density of drilling fluid, but density is greater than 9.0lbs/gal.If include the high solid of content, then before acidifying, the halogenide waste liquid should be filtered, to remove solid.If remove degrease residue and other solid earlier before processing, then this method is more effective.Separation method before the acidifying can remove grease.This separation method comprises the oil in water emulsion instability, uses appropriate method well known in the art with the oil phase physical sepn then.
The method according to this invention, a primary and foremost purpose of regeneration halogenide waste liquid is to improve the ionogen that loses in oil well operation or this liquid process of industrial application.In a preferred method, before adding the electrolyte content of chemical substance, calculate the initial density of the halogenide liquid that reclaims with regeneration halogenide waste liquid, analyze its chemical constitution.After the analysis, select and quantitatively be used to neutralize excessive acid and the electrolytical suitable alkali of regenerating and losing.For example,, then can use in the calcium oxide and excessive acid if the halogenide liquid that reclaims is calcium chloride, thus the regeneration calcium ion.
In the actual preferred method of the present invention, in halogenide waste liquid 60, add acid 50, with this liquid of acidifying.The initial composition of halogenide waste liquid 60 can comprise moisture zinc bromide or moisture Calcium Bromide.Also can use calcium and the halogenide of zinc and the mixture of bromide of various ratios.For example, moisture zinc bromide and Calcium Bromide, zinc bromide and calcium chloride or zinc chloride and Calcium Bromide.To avoid the precipitation of metal-salt during acidifying, particularly have under the situation of zinc and calcium.If the halogenide waste liquid comprises base metal, then pH is 0-6, preferred 0-5.5.If the halogenide waste liquid comprises basic metal or alkaline-earth metal, then pH is preferably 0-10.Be used for acidifying acid 50 and can comprise Hydrogen bromide.This acid can also comprise spirit of salt or organic acid.
