摘要： A method and device evaluate simultaneously, with the same equipment, physical parameters such as the absolute permeability and the porosity of fragments taken from a fragmented natural or artificial porous medium. The porosity of the fragments is measured by means of helium pressure tests according to a protocol known in the art. The chamber (1) containing the fragments is communicated with a tank (11) whose volume is also known and containing helium at a known pressure. At pressure balance, the value of the solid volume can be deduced. The rock envelope volume and the fragments mass are also measured. Combining these measurements allows to determine the porosity of the samples and the density of the rock. Their permeability is then measured by immersing them in a viscous fluid and by communicating the chamber with viscous fluid at a determined pressure contained in a vessel (9) so as to compress the gas trapped in the pores of the rock, according to two different protocols. The values of the physical parameters are determined by modelling the evolution of the pressure or of the volume in the chamber and by means of an iterative adjustment.

摘要： A pressurizable sample chamber of known volume holds a sample with unknown porosity characteristics. The sample chamber has a known pressure (or vacuum). A flow controller preferably controls the flow of the pure gas to be adsorbed by the sample in the sample chamber. A pressure monitor preferably monitors the pressure in the sample chamber. Once the pressure approaches a target pressure, the flow controller is closed. The pressure monitor continues to monitor the pressure until it stops changing when an equilibrium is attained. The amount of gas introduced into the system through the flow controller and the volume and final pressure of the sample chamber are used to calculate the amount of gas adsorbed. This calculation is subsequently used to determine the porosity characteristics of the sample. Some of these characteristics include, but are not limited to, pore distribution and surface area.

摘要： A porous sample is alternately saturated with at least two saturating fluids with known different thermal conductivities. As at least one saturating fluid a mixture of at least two fluids is used with known and different thermal conductivities. After each saturation thermal conductivity of the saturated sample is measured, and pore space characteristics and matrix thermal conductivity are determined based on the results of thermal conductivity measurements.

摘要： A method of determining the proportions of different powders in a powder comprises obtaining a sample of a powder, adding and mixing the sample into a molten material and freezing the mixture of powder and molten material to form a block. Computed tomography is performed on the block to produce a three-dimensional image of the block, the three-dimensional image of the block comprises a first shade, a second and a third shade corresponding to the material, a first powder particle and a sec and powder particle. The three-dimensional image of the block is analyzed to count the number of regions exhibiting the second shade and the third shade corresponding to the number of first powder particles and second powder particles respectively. The fraction of second particles in the powder is determined by dividing the number of second powder particles by the sum of the number of first powder particles and the number of second powder particles.

摘要： Method and device for evaluating, simultaneously and with a single equipment, physical parameters such as the absolute permeability and the porosity of fragments taken from a fragmented artificial or natural porous medium. The porosity of the fragments is measured by means of pressure tests using helium or any other gas, according to a protocol known in the art. Chamber (1) in which they are contained is communicated with a tank (11) of known volume containing helium at a known pressure. At pressure balance, the value of the solid volume can be deduced. The rock envelope volume and the mass in fragments are also measured. The porosity of the samples and the density of the rock are determined by combining these measurements. Their permeability is then measured by immersing them in a liquid and by communicating the chamber with a liquid initially at a predetermined pressure contained in an accumulator (9) so as to compress the gas trapped in the pores of the rock. The values of the physical parameters are determined by modelling the evolution of the volume of liquid injected in the chamber and by means of an iterative adjustment. Applications: petrophysical measurements from drill cuttings or crushed cores for example.

摘要： A sample is disposed in a sample chamber and is connected by a flow restrictor or "leak" to a bulb of known volume. In adsorption studies, an on/off valve is opened, allowing gas to flow from the bulb into the sample chamber. The leak controls the rate of flow to be less than the equilibrium rate of adsorption/desorption of gas with respect to the sample, such that the pressure in the sample chamber at all times is an equilibrium value. The pressure in the bulb and in the sample chamber are both measured repetitively. The change in pressure in the bulb provides an indication of the net amount of gas admitted to the sample chamber. This quantity together with the change in pressure in the sample chamber can be used to provide an indication of the amount of gas which is adsorbed onto the sample. In desorption studies the bulb is evacuated relative to the sample chamber. The on/off valve is opened to allow gas to flow from the sample chamber into the bulb at a rate controlled by the leak to be less than the equilibrium rate of adsorption/desorption such that the pressure within the sample chamber is at all times an equilibrium value. Points on the adsorption and desorption isotherms can thus be determined continually.
