摘要： Inside a syringe (1) slides a plunger (2) which bears a joint (4) sliding sealingly over the internal wall of the syringe. The flexible membrane (6) of the joint (4) fixed to the end of the plunger (2) bears a closing component (25, 27) which follows the movement of deformation or displacement of the membrane through the effect of the pressure built up during the injection stage, but which is retained by immobilizing strips (17) in a position in which it opens the orifice, breaking the seal between the top and the bottom of the joint, as soon as the membrane returns to its initial position.

摘要： The present invention relates to the processes and devices for assessing the permeability of a rock medium 1 containing a fluid 2 in its interstices 3. The device and the process according to the invention are characterized essentially in that a given magnetic field is applied to the interstitial fluid 2 located in the rock medium 1, the variation in pressure of the interstitial fluid 2 resulting from the application of the magnetic field is measured, and the permeability of the rock medium is determined as a function of the value of the variation in pressure of the interstitial fluid.

摘要： A method and the apparatus for in situ analysis of a rock formation that already contains fluid in its interstices an excitation device is provided for imparting motion to the fluid relative to the rock formation and the magnetic fields created by the relative motion of the fluid in the rock formation measured. The permeability of the rock formation are deduced from the measurement. The measurement system is particularly applicable to in situ measurement of the permeability of rocks, e.g. down an oil well.
