摘要： The device includes a cell for a sample, delimited lengthwise by two end pieces (7, 8) and laterally by a deformable sheath (17). The end pieces are traversed by channels (14) which place their grooved inside faces in communication respectively with two sources (14, 15) at an adjustable pressure delivering respectively a first and a second fluid. Between the inside faces of the end pieces and the sample, two semipermeable membranes (12, 13) are disposed, which are permeable respectively to the first and to the second fluid. Electrodes (18, 19) are placed inside sheath (17) in contact with the sample and connected to a system (24) for measuring the electrical conductivity of the sample. The cell is placed in a body (1) associated with pressure means (28) for applying a confinement pressure to sheath (17) and membranes (12, 13). The device is designed to operate at relatively high temperatures.

摘要： Device intended for measurements on a porous rock bar in the presence of fluids including a containment cell comprising an elongate body (2) closed at the opposite ends thereof by end pieces (6, 7) and sources of pressurized fluids allowing displacement under pressure, within the sample, of a first wetting fluid and of a second fluid. One or more selectively wettable rigid membranes consisting each of a relatively thin layer of a porous ceramic on a support layer made from a porous material are pressed against the ends of the sample. The membranes can for example be made by sintering of metallic grains of unequal size (the grains are much coarser for the support layer). Such membranes have good resistance to high temperatures of the order of several hundred .degree.C. Electrodes (E1) connected to a measuring device (24) are used to determine physical characteristics of the bar. The device can be used for oil reservoir engineering notably.

摘要： A method for measuring the conducting fluid saturation and the resistivity of a porous medium have application to development of underground geological formations. A solid sample is extracted from the medium and placed in a centrifugation cell, beside a second sample for limiting the capillary end effect in the first sample. The two samples are partly desaturated by subjecting them to centrifugation. The resistivity of the sample is measured by placing it in a radial-electrode resistivity measurement cell. The saturation of the sample is then determined by measuring its nuclear magnetization by means of an NMR device. Repeating this procedure for different centrifugation velocities provides resistivity and saturation pairs allowing a relationship between saturation and resistivity to be estimated.

摘要： A method measures the physical characteristics of at least one solid porous sample (S) saturated with a first fluid by carrying out drainage or imbibition phases, in the presence of a second fluid with a different density from that of the first fluid. A sample saturated with a first fluid, such as brine, is placed in a vessel filled with a second fluid. By means of a centrifugation assembly, the sample is drained until a final saturation pressure is established in the sample. In a second phase, the sample can be soaked. The drainage or imbibition phases are carried out by interposing a porous plate (1) between the sample (S) and the vessel in which it is placed, the porous plate being wettable by the first fluid or the second fluid with preferably an inlet pressure greater than the highest capillary pressure imposed on the face of the sample in contact with the porous plate and perforated with perforations whose number and cross section are adjusted to enable rapid drainage of the fluid contained in the core sample and obtain a substantially uniform saturation profile. The method is applicable in particular to petrophysical measurements.

摘要： A method for determining the variations of the resistivity index (RI) of a family of rock samples of complex pore structure with at least two pore networks, as a function of the water saturation (Sw), and in the presence of a non-oil conducting fluid. The volume fraction (f1, f2, f3) occupied by each pore network and the distribution of the pore throats in the various pore networks are determined for each sample of the family. The values of coefficients relating the variation of its electrical resistivity as a function of its water saturation (Sw) are experimentally determined on a sample of the family used as a reference sample. The resistivity index (RI) of all the samples of the family is then determined on the basis of the variation of parameters describing the layout of the pore network, and using the values of the coefficients measured on the reference sample. The method allows measurement of a continuous resistivity index curve which is not obtained, as in conventional techniques, from only a limited number of points at capillary equilibrium.

摘要： A method for faster determination of physical parameters (capillary pressure curves and relative permeabilities for example) of a geologic sample initially saturated with a first fluid placed in a vessel and subjected to centrifugation in the presence of a second fluid. The equilibrium saturations are determined before complete stabilization is reached through analytic modelling involving exponential functions, best adjusting to an effective production curve, for each speed stage. A database, obtained by means of various simulations, is used to obtain the relative permeability curves corresponding to the centrifuged sample. The method can be applied for measurement of petrophysical characteristics.
