摘要： An apparatus including a drill collar having an outer surface, an assembly for interaction with an earth formation coupled to the drill collar, the assembly including a first member to extend beyond the drill collar outer surface and a second member to extend beyond the first member and toward the earth formation to receive formation fluids. An apparatus including an MWD tool having an outer surface, a formation testing assembly coupled to the MWD tool, the formation testing assembly recessed beneath the outer surface in a first position and including a piston to extend beyond the outer surface to a second position and an inner sampling member to extend beyond the piston to a third position.

摘要： A pressure regulator for dirty fluid service includes: a body having a chamber, a pair of supply sockets, and an outlet port, each socket and the port formed through a wall of the body; a pair of supply seal plates disposed in the supply sockets and having supply passages formed therethrough; and a sliding seal assembly disposed in the chamber. The sliding seal assembly includes: a seal carrier having a piston and a supply gland; and a supply seal disposed in the supply gland. The piston is disposed in a pilot portion of the chamber. The outlet port and sockets are located adjacent to a regulated portion of the chamber. The piston is operable to move the sliding seal assembly between a supply position and a second position in response to pressure differential between the pilot portion and the regulated portion.

摘要： A formation testing tool is described herein, including a formation probe assembly having an extendable sampling probe surrounded by a cylindrical sleeve. The sleeve is configured to engage a metal skirt having an elastomeric seal pad coupled thereto. The skirt and seal are configured to be field replaceable. The elastomeric pad has a non-planar outer surface which engages a borehole wall in preparation for formation testing. The seal pad may be donut-shaped, having an aperture through the middle of the seal pad. The seal pad and its surface may include numerous different embodiments, including having a curved profile. The seal pad may also include numerous different embodiments of means for coupling the seal pad to the metal skirt. The formation testing tool also includes formation probe assembly anti-rotation means, a deviated non-circular flowbore, and at least one closed hydraulic fluid chamber for balancing fluid pressures.
