Abstract
The present invention relates to an automatic continuous online metering method for oil-water mixtures and a device thereof. The narrow neck of an overflow barrel is provided with a feeding pipe, and the lower end of the feeding pipe is sheathed with a thin film isolation bag; the overflow barrel is filled with working liquid; the thin film isolation bag is freely expanded along with the increase of the volume of a measured mixture; the extruded working liquid enters a containing overflow barrel through an overflow pipe; two electronic balances measure the volume and the weight of the measured mixture; a microcomputer processes a mathematic model to obtain the total flow rate of the measured mixture and the respective content and the respective spilt flow quantity of oil and water.
Description
The invention relates to oil water mixture automatic gauge method and device thereof.
At present, oily in the oil water mixture in industry and the laboratory, liquid water content analysis is mostly adopted (1) photoelectric colorimetry, (2) partition method.These method troublesome poerations, efficient is low, and real-time is poor.Especially when oil, the strong emulsification of water, partition method lost efficacy.For example in heavy crude heat extraction laboratory steam or the hot water drive's physical simulation experiment, output liquid (oil water mixture) is oil-water emulsion, is difficult to separate, because breakdown of emulsion itself is exactly a difficult problem, so be difficult to separate behind the first breakdown of emulsion.Therefore the oil and water separation method is difficult to realize real-time, the accurate measurement of output liquid oil, liquid water content.In the experiment as SPEJ June 1980 P151-174 report, output liquid is collected in the graduated cylinder, adds emulsion breaker, waits for a period of time, and treats to read oil, water volume separately more respectively after the profit layering.Because the breakdown of emulsion difficulty, Water-In-Oil, oil-in-water are serious, and the effect of separation is bad, are difficult in real time, accurately metering oil, liquid water content.
The purpose of this invention is to provide a kind of oil, water automatic gauge method and device thereof, it can be to the oil in the oil water mixture of strong emulsification, liquid water content, and flow carries out continuously on-line automatic metering.Has real-time, accurate, easy to operate, the simple advantage of equipment.
The present invention uses the simple physics principle, it is simple to have made a nested structure, easy to operate device, be used for measuring volume and weight (or two kinds of density differences of oil water mixture, the volume and weight of mutual undissolved liquid mixture), because during heavy crude heat extraction physical simulation experiment or some other analysis are tested in industrial flow test and the laboratory, the density of oil, water is known quantity, volume according to mixing material equals the supposition of liquid volume sum separately, gives fuel-displaced, liquid water content Vo, V by following linear equation in two unknowns group

Feature of the present invention is, measuring apparatus adopts an overflow cylinder, it has a thin neck, the ratio of its diameter and barrel diameter is advisable less than 0.2, and run-down pipe is housed, it has determined the accurate volume of overflow cylinder, a film isolation pocket is housed in the overflow cylinder, isolation pocket is used for holding the measured oil aqueous mixtures, extrude the working fluid (this volume is the volume of potpourri) of equal volume in the overflow cylinder simultaneously, the working fluid of extruding flows into through run-down pipe and contains the tube that overflows, by two electronic balance weighings, make oil water mixture stereometry usefulness for one, another is made the oil water mixture gravimetry and uses.A MICROCOMPUTER PROCESSING, the group that is used for solving an equation obtains in the oil water mixture oil, liquid water content, and that binding time gets is fuel-displaced, moisture flow and potpourri total flow.
Adopt this metering method and device thereof to remove manually-operated from, can measure the content and the flow of each component in the liquid mixture that oil water mixture (even strong emulsification) or other two kinds do not dissolve mutually, density is different continuously, online, improve efficient, improved precision.
Description of drawings: oil water mixture self-measuring device structural drawing, (1) feed pipe, (2) working fluid induction pipe, (3) film isolation pocket, (4) overflow cylinder, (5) run-down pipe, (6) Sheng Yiguan, (7) electronic balance A, (8) electronic balance B, (9) microcomputer.
Describe method of the present invention and device thereof in conjunction with the accompanying drawings in detail: feed pipe (1) is used for the measured oil aqueous mixtures is imported the film isolation pocket (3) of its lower end, the film isolation pocket is made with materials such as plastics, rubber, latexes, its softness, can freely swell and shrivel, its purposes is to store tested potpourri, and measured medium and working fluid are separated.Working fluid induction pipe (2) is the inlet of working fluid, and the purposes of working fluid is that its density is less than the density of tested potpourri for the volume usefulness of measuring tested potpourri.The purposes of working fluid induction pipe is, before the measurement, from this mouth working fluid imported overflow cylinder (4), and the air in the extrusion film isolation pocket is till run-down pipe (5) has working fluid to flow out.When tested potpourri entered the film isolation pocket, the isolation pocket distending was extruded working fluid interior in the overflow cylinder simultaneously.Working fluid flows into through run-down pipe and contains the tube (6) that overflows, the volume of the working fluid that overflows just equals the volume of tested potpourri in the isolation pocket, obtain by electronic balance (7) weighing, electronic balance (8) weighs up the weight (the weighing mode of electronic balance (7) and (8) also can adopt other mode) of tested potpourri in the film isolation pocket.Because oil, the density of water and the density of working fluid are known quantities in the oil water mixture, separate above-mentioned digital model (linear equation in two unknowns) with microcomputer (9), promptly get oil, liquid water content, shunt volume and total flow in the measured oil aqueous mixtures.
Embodiment: " thickened oil recovery physical simulation hi-line model output liquid-oil water mixture oil, liquid water content automatic gauge ", the oil water mixture that measured medium is the emulsification that is difficult to separate, working fluid is a kerosene, the internal diameter of overflow cylinder is 140 millimeters, cylindrical shell is high 422 millimeters, the internal diameter of knapsack is 140 millimeters, height is 265 millimeters, the internal diameter of thin neck is 20 millimeters, height is 96 millimeters, and the run-down pipe internal diameter is 8 millimeters, and the run-down pipe height is 40 millimeters, the film isolation pocket is a polybag, and the model of two electronic balances is MD8000.
