Abstract
The invention relates to a rock electrokinetic permeability measurement method. A core sample is placed in a streaming potential experiment core holder or an electroosmosis experiment core holder, and the confining pressure is kept at 1.2Mpa. In a streaming potential experiment, the alternating pressure generated by a vibrating diaphragm is utilized to push saline water to cyclically reciprocate, so that pressure difference is produced between both ends of the core sample, and when the saline water flows through the core sample, because of the affection of the double-electrode layer effect in the core sample, part of movable charged ions can move along with the saline water under the action of viscous force to form current. In an electroosmosis experiment, when current flows through the core sample, the potential difference is produced between both ends, the hydrones in the core sample can flow along with the current to form electroosmosis liquid flow, the liquid is compressed by one end into which the liquid flows, and is expanded by the other end out of which the liquid flows, as a result, pressure difference is produced between both ends of the core sample, and the permeability is then worked out. The method macroscopically measures the permeability as a microscopic parameter within a low-frequency range.

Embodiment
The factor of porosity that uses core sample in the experiment is between 20%-30%.Laboratory sample is the right cylinder rock core of 1 inch of diameter, uses core cutter that its length is cut into 2cm, avoids during cutting having the unfilled corner that can not repair on core sample cylinder and the end face as far as possible, guarantees that both ends of the surface are smooth and vertical with cylinder axis.In addition, core sample will clean before use, washes impurity earlier off, uses the phenixin washing oil then, uses the absolute ethyl alcohol desalinization of soil by flooding or leaching.Test produces very big influence to electrokinetic potential and electric osmose in the existence meeting of bubble, so must to solution and core sample is found time and saturated fully before experiment.The solution that uses in the experiment is the salt solution of concentration as 0.05mol/L.
Core holding unit is made up of electrokinetic potential experiment core holding unit and electric osmose experiment core holding unit.
Electrokinetic potential experiment core holding unit is made up of conduction electrode 1, tank 2, potential electrode 3, rubber sleeve 4, clamper 8, fixed mount 9, display pipe 10, bracing frame 11, vibrating membrane 15;
Electric osmose experiment core holding unit structure and electrokinetic potential core holding unit structure are basic identical, and different is that the clamper both sides are ring electrode and do not have vibrating membrane, core holding unit to be provided with pressure transducer, and pressure transducer is connected on the two ends of core sample respectively.
Because electrokinetic potential is different to the requirement of device with the electric osmose experiment, so designed two cover core holding unit Fig. 1 according to the experiment needs, Fig. 2 is respectively applied for electric osmose experiment and electrokinetic potential experiment.The difference of two kinds of devices mainly is that the design of right circles cylinder tank is different, and what install in the electric osmose experiment is electrode, and what install in the electrokinetic potential experiment is vibrating membrane.Circular electrode neither influences the circulation of electric current, flow, thereby the contact area that has increased electrode is again avoided the electrode polarization influence that causes because of current density is excessive.In the experiment rock core is lain in a horizontal plane in the middle pipeline; Both ends of the surface are vertical with desktop; In order to guarantee that flow, electric current only pass through from rock core inside, and can be from the mixed lateral column surface current mistake of rock core, therefore; Clamper in the experiment has increased by one specially and has added the confined pressure system, avoids measurement data to exist than mistake.There is one section plantation rubber pipe box at clamper horizontal pipe middle part, and the rubber sleeve inwall only closely contacts with rock core outside cylinder when not pressurizeing, and does not have squeezing action between the two.In the experiment gases at high pressure are injected in the confined pressure chamber from air intake opening, and keep about confined pressure 1.2MPa, make the rubber tube cover tightly " hold " rock core, so just force flow, electric current to pass through, guarantee the accuracy of experiment from rock core inside.Whole clamper is made with organic glass and the such rigid material of stainless steel, thereby does not exist in the experiment because the error that the compressibility of device causes.
Electrode is made: electrode comprises conduction electrode and potential electrode
Because the difference of use-pattern, the finished product Ag/AgCl electrode in the conventional galvanochemistry specialty does not meet requirement of experiment, so the Ag/AgCl electrode that uses in the experiment needs special the making.Electrode is by a diameter 1.2mm, and purity is that 99.9% filamentary silver curves concentric polycyclic and in the HCl of 1mol/L plating bath, electroplates and form.
Moving electric coupling coefficient measuring method
In the electrokinetic potential experiment; Signal source outputs to lock-in amplifier; After amplifying, supply with vibrator; The vibration in vibrator cycle makes exciting rod pair and its vibrating membrane that closely contacts produce the pressure of an alternation, and then promotes the to-and-fro movement in salt solution cycle, will form pressure differential at the rock core two ends like this.When brine stream is crossed rock core; Because the influence of the inner electrostatic double layer effect of rock core, the effect next part of viscous force movably charged ion can follow salt solution to move together, form electric current; Be referred to as streaming current; Because rock core has a constant impedance,, be called electrokinetic potential so when electric current flows through rock core, will produce potential difference (PD) at the rock core two ends.Meanwhile, form convection current because charged ion can produce a reversed electric field in the accumulation of rock core one end, and the part charged ion will be done counter motion under effect of electric field.After system balancing, two kinds of electric currents are cancelled out each other, and total current is zero.
In electric osmose experiment, whole device all is airtight, gives the excitation of AC constant-current source low-frequency ac by signal source, make its produce one with the low-frequency ac electric current of signal source with frequency.When electric current passes through rock core; Will form potential difference (PD) at its two ends, the inner hydrone of rock core can follow electric current to flow together simultaneously, forms the electric osmose flow; Because the two ends tank is airtight; This will produce compression to liquid at the end that flow flows into, and an end that flows out makes expansion of liquids, thereby causes the rock core two ends to form pressure differential.Under action of pressure, can produce reflux stream, two kinds of flows are cancelled out each other after system reaches balance, and total flow is zero.
Rock moves electro-osmosis rate measuring method
Though the electrokinetic potential experiment is different with electric osmose experiment energisation mode, all is after system balancing in the experiment, measures the potential difference (PD) and the pressure differential at rock core two ends.Potential difference (PD) is drawn signal by the Ag/AgCl potential electrode at rock core two ends.The pressure differential signal detects with differential pressure pick-up.According to the difference of pressure limit, select for use in the experiment two kinds of differential pressure pick-up 26PC (10V DC, 1psi) and DC001 (5VDC 250Pa), is respectively applied for the pressure differential at measurement rock core two ends in electrokinetic potential experiment and the electric osmose experiment.But because these signals are very faint, maybe be all fainter than ambient noise signal on every side.For faint like this AC signal, experiment has been chosen to be specifically designed to and has been detected the lock-in amplifier that buries faint AC signal in noise, and this measuring accuracy for voltage and current can reach nV level and pA level.Lock-in amplifier request for utilization measured signal and reference signal have same frequency, so reference signal and pumping signal all are to be provided by same signal source in two experiments, have guaranteed that lock-in amplifier can normally accurately measure.Here use two stand lock phase amplifiers to constitute two phaselocked loops, measure the amplitude and the phase place of potential difference (PD), pressure differential simultaneously.And then obtain electrokinetic potential coefficient and electric osmose pressure coefficient.And conductivity can be converted out by electrical relation according to measurement result.Finally obtain the permeability of rock core.
