Technical field:
What the present invention relates to is a kind of electric copying device being applicable to percolation rule in heavy oil reservoir.
Background technology:
Water power analogue experiment installation utilizes the water power principle of similitude and develops, and 1933 start the research being applied to petrol-gas permeation fluid mechanics.Mainly adopt 30 ~ fifties of 20th century mathematical method and physical simulating method Researching Oil-gas Seepage problems.Water power analogue experiment installation have structure simple, easy to operate, can intuitively react the advantages such as underground fluid percolation law, be therefore widely used.Recently, with the complex structural well that horizontal well, Multilateral Wells etc. are representative, its seepage flow mechanism is very complicated, and adopts water power simulated experiment can simulate the fringe conditions of various Holes of Complicated Wells easily, and directly observe the mobility status of fluid, and be easy to measure isobar distribution etc.Its result can also be used to the accuracy checking numerical simulation and analytic solutions.
Water power analogue experiment installation also can be used for studying fracturing, and this technology starts application the end of the forties to the beginning of the sixties.The method be still utilize the water power principle of similitude long to the fracture pattern studied fracturing and formed, seam, stitch wide, stitch high, conductivity, fracture condudtiviy and the relation between other parameter and stimulation ratio, design in order to instruct fracturing technology and construct with mining site.The investment of electric analogy method research pressure break problem is little, be widely used, experimental period is short, the degree of accuracy is high, has general directive significance.
In prior art, mostly be the measurement of two dimensional surface electromotive force to reflect potential energy in stratum, thus obtain the equipotential lines of two dimension; The conventional oil reservoir of analog, cannot simulate hypotonic, the heavy crude reservoir with free-boundary problem.
Summary of the invention:
The object of the invention is to overcome the deficiencies in the prior art, a kind of electric copying device being applicable to percolation rule in heavy oil reservoir is provided.
In order to solve the problem existing for background technology, the present invention by the following technical solutions:
Be applicable to an electric copying device for percolation rule in heavy oil reservoir, it is made up of at the bottom of power supply, ammeter, ECU, switch, ballast, simulation well or crack, probe, reservoir;
By electric wire, power supply, ammeter, ECU, ballast are connected successively, finally be connected to simulating boundary place, simulating boundary is placed in reservoir, at the bottom of simulation well or crack is placed in reservoir center and directly connects power cathode, can freely at three-dimensional direction moving in probe and reservoir, voltmeter, ECU are parallel at the bottom of probe and simulation well or between crack;
During work, after ECU adjusts frequency, waveform, voltage, turn on-switch, ballast is started working, voltage transient is increased to kilovolt and reaches electrolyte breakdown voltage, puncture rear voltage resume and be stable at preset state, its data such as full range voltage, curent change are by ECU record and store.By changing the position measurement of probe in reservoir and the electromotive force recorded under different coordinate.
Further, be covered with dielectric film outside described probes probes, only end exposes 1mm metal probe.
Further, described ballast can instantaneous raising input voltage until reach breakdown voltage, can by burning voltage after electrolyte is breakdown, the change of this process voltage can by ECU record.
Further, the electrolyte added in described reservoir is formed by mineral oil and vegetable oil mixing preparation, is changed its acid number by change mineral oil and vegetable oil mixed ratio and then is regulated its electric conductivity and breakdown voltage.
Further, described simulating boundary is made up of satisfactory electrical conductivity metal.
The present invention contrasts prior art following beneficial effect: apparatus of the present invention can apply to the heavy crude reservoir with free-boundary problem, simulates three dimensional fluid flow rule; Use mineral oil formula to substitute traditional electrolyte, make it to there is breakdown voltage and effectively can simulate free-boundary problem, and effectively alleviate Electrolysis.
Accompanying drawing illustrates:
Fig. 1 is composition structure of the present invention and schematic diagram.
Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Fig. 1 is composition structure of the present invention and schematic diagram.Be applicable to an electric copying device for percolation rule in heavy oil reservoir, it is made up of at the bottom of power supply, ammeter, ECU, switch, ballast, simulation well or crack, probe, reservoir; 1-power supply; 2-ammeter; 3,10-ECU: possess frequency conversion, adjustment waveform, voltage, alternating current-direct current and data recording function; 4-switch; 5-ballast: instantaneous voltage can be increased to upper kilovolt to meet breakdown voltage condition, and after puncturing stabling current; At the bottom of 6-simulation well or crack; 7-probe: be covered with dielectric film outside probe, only end exposes 1mm metal probe, and during to reduce probe and reservoir deep, superficial part electric field is on the impact tested, and improves vertical certainty of measurement; 8-reservoir: degree of depth 1m, can effectively simulate vertical percolation law; 9-simulating boundary
Wherein, be covered with dielectric film outside described probes probes, only end exposes 1mm metal probe; Described ballast can instantaneous raising input voltage until reach breakdown voltage, can by burning voltage after electrolyte is breakdown, the change of this process voltage can by ECU record; The electrolyte added in described reservoir is formed by mineral oil and vegetable oil mixing preparation, is changed its acid number by change mineral oil and vegetable oil mixed ratio and then is regulated its electric conductivity and breakdown voltage; Further, described simulating boundary is made up of, as copper etc. satisfactory electrical conductivity metal.
Apparatus of the present invention workflow: after adjusting frequency, waveform, voltage by ECU, turn on-switch, ballast is started working, voltage transient is increased to kilovolt and reaches electrolyte breakdown voltage, puncture rear voltage resume and be stable at preset state, its data such as full range voltage, curent change are by ECU record and store.By changing the position measurement of probe in reservoir and the electromotive force recorded under different coordinate.
The free-boundary problem of oil reservoir is simulated by the breakdown voltage of electrolyte, because normal experiment electrolyte does not exist breakdown voltage, thus the electrolyte by mineral oil and vegetable oil mixture is used in this device, its electric conductivity and breakdown voltage are relevant to self acid number of oil, different acid number can be reached from vegetable oil proportioning by different minerals oil, and then obtain the electrolyte of different electric conductivity and breakdown voltage, the oil reservoir of multiple tape starting barometric gradient can be simulated.
