Estimating the term…
The present invention relates to a device used for the direct measurement of the permeability of rock fragments coming directly from the drilling of an oil well and commonly called cuttings, consisting of a hollow cylindrical body (c) that presents an inlet hole for the fluid (i), a thread for closing it (h) and a hydraulic seal (g) in which is placed the sample holder disk (d) which rests on the seal (g) and is overlapped by a porous sintered steel septum (e) on which a closing plug (f) is situated with an outlet hole for the fluid (i') and the same is also provided with a thread (h') to enable it to close on the body (c). The device can be used to obtain, directly on site, the measurement of permeability along the whole length of an oil well.
A device used for the direct measurement of the permeability of rock fragments coming directly from the drilling of an oil well, commonly called cuttings which have dimensions less than one centimeter, said device consisting of a hollow cylindrical body (c) that presents an inlet hole for receiving fluids (i), surfaces defining said hole having threads (h) for receiving a closing plug having threads (h') for engaging threads (h) and a hydraulic seal (g) in which is placed a sample holder disk (d) which rests on the seal (g) and is overlapped by a porous sintered steel septum (e) on which a closing plug (f) is situated with an outlet hole for the passage of fluids (i'), the closing plug is suitable to allow the closure of the hole on the cylindrical body (c), the sample holder disk (d) consists of a resin (b) in which cuttings (a) are encapsulated, which presents flat, parallel faces with the two surfaces of each encapsulated cutting exposed on each side.
