Description
One, technical field
The utility model relates to a kind of rock electrical measurement device, is a kind of rock core resistance measurement clamper concretely.
Two, background technology
At present, two utmost point methods are that the laboratory is carried out normal temperature and pressure resistance (rate) measurement a kind of method relatively more commonly used according to ohm theorem to the plunger rock core.The enforcement of this method, be by arranging that in plunger rock core both sides a pair of cylinder (sheet) shape electrode applies electric field as transmitting electrode in rock core inside, by measuring two interelectrode voltages and the strength of current of rock core of flowing through calculates resistance, the resistivity that obtains rock core in conjunction with the diameter and the length computation of rock core.Usually,, cause electrode and rock core end face to leave the space easily,, can increase contact resistance, make the measurement result of rock core resistance (rate) bigger than normal than truth because the air in the space is non-conductive because core surface has certain roughness.Therefore, at present the rock physics laboratory often uses the cotton (yarn) of salt water-wet or wet filter paper (industry standard SY/T 5385-2007) to impel it to be coupled as coupling material by the pressure between control electrode and the rock core to reduce contact resistance.But, in the practical operation, be difficult to control cotton (yarn) or the mesohalobic quantity of filter paper, resistance (rate) is little at most, even can be owing to salt solution enters the saturation degree that rock core changes rock, resistance (rate) is big at least, and contact resistance is difficult to control and scale is determined, the not homogeneous measurement result fluctuation of the rock core of same saturation degree is bigger, poor repeatability.
Three, utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of rock core resistance measurement clamper simple in structure, with low cost is provided.
Its technical scheme is: comprise base, regulate guide rail, resistance measurement electrode and flexible solid electric conductor, base connects pressure cylinder and regulates guide rail by supporting seat, pressure cylinder one side is provided with tensimeter, regulate guide rail one side and be provided with control hand wheel, regulate guide rail and connect the insulation connector, the insulation connector connects the resistance measurement electrode, and the resistance measurement electrode connects rock core to be measured by the flexible solid electric conductor.
The utility model is simple in structure, easy to use, with low cost, and solid conductive material couplings electrical property is stable also can be demarcated, reusable.
Four, description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of the utility model.
