摘要： A method of sampling fluid from a rock formation penetrated by a borehole includes positioning a downhole tool having a flow line in the borehole, establishing an inlet port through which fluid passes from a first point in the formation into the flow line, establishing an outlet port through which fluid passes from the flow line into a second point in the formation, and passing fluid between the formation and the flow line through the inlet and outlet ports.

摘要： Methods and apparatuses for sampling fluid from a subterranean formation penetrated by a wellbore are provided. The subterranean formation has clean formation fluid therein, and the wellbore has a contaminated fluid therein extending into an invaded zone about the wellbore. A shaft is extended from a housing and positioned in a perforation in a sidewall of the wellbore. At least one flowline extends through the shaft and into the housing. The flowline(s) are adapted to receive downhole fluids through the perforation. At least one fluid restrictor, such as a packer, injection fluid or flow inhibitor, may be used to isolate at least a portion of the perforation whereby contaminated fluid is prevented from entering the isolated portion of the perforation. At least one pump selectively draws fluid into the flowline(s).

摘要： The present invention provides methods and apparatus for determining flow velocity within a formation utilizing nuclear magnetic resonance (NMR) techniques in which the shape of the resonance region is restricted so that sensitivity to radial flow or vertical flow is obtained (or both when more than one NMR tool is used). Flow velocity using these NMR tools is determined using decay amplitude, frequency displacement or stimulated echoes (where the spins are stored along the magnetic field instead of the transverse plane to exploit echo decays and frequency displacements) based on the application of adiabatic pulses. Based on the described NMR measurement of flow velocity, additional wellbore parameters may be obtained such as a direct measurement of permeability, an assessment of drilling damage to the wellbore, formation pressure, invasion rate of the mud filtrate or the migration of fine mud particles during sampling operations.

摘要： An operating mechanism (50,182) for providing mechanical advantage for mating and unmating a fixture (10) to a receiver (150) manually at a separable interface for mating complementary arrays of electrical connectors (12,152) for use in testing equipment. The leading end (80,88) of the operating mechanism (50) of the fixture is inserted into a receptacle (182) of the receiver and locks to secure the fixture to the receiver, simultaneously unlocking a subassembly (58) within the operating mechanism to be manually rotated to fully mate the now-adjacent arrays of connectors. The subassembly (58) is movably secured within an outer barrel (54) affixed to a frame (20) of the fixture and includes an axially spring biased central shaft (70) movable within an inner barrel (72). Arrays of locking balls (76,82) within apertures 86,90) of the inner barrel move between annular grooves 78,84) of the central shaft (70) and annular grooves 186,142) of a surrounding cylinder (either the receptacle 182) or the outer barrel (54)) to lock and unlock the central shaft from being axially moved with respect to the particular surrounding cylinder. An acme screw (100) within the operating mechanism converts manual rotation of a handle (52) into gradual axial movement with substantially enhanced force.
