摘要： Fluid is loaded into a subterranean formation (14) using an intensifier (34) comprising a power section (36) and a pump section (38). The power section includes a housing (42), a sleeve (44) slidably disposed within the housing (42), a piston (48) defining an interior volume (50), the piston being slidably disposed within the sleeve (44) and within the housing (42) such that a fluid pressure within the interior volume (50) causes the sleeve (44) to oscillate relative to the housing (42) and causes the piston (48) to oscillate relative to the sleeve (44) and the housing (42). The pump section (38) is operably associated with the piston such that the fluid pressure from the interior volume (50) is intensified in the pump section (38) and injected into the formation (14) as the piston (48) oscillates relative to the housing (42).

摘要： A method and apparatus for determining the length of a fluid conduit using acoustics. The method and apparatus can be used for determining the length of an unblocked section of a fluid conduit (10), the unblocked section of the fluid conduit having a proximal (12) and distal (14) end. The apparatus comprises an extension conduit (18) of a known length having a proximal (28) and distal (32) end, the proximal end of the extension conduit (18) being operably connectable to the proximal end (12) of the fluid conduit (10). A pressure change sensing device (16) is operably connected to the proximal end (28) of the extension conduit (18). A pressure wave generator (24) operably connected to the interior of the extension conduit (18). The method involves determining the length of the conduit, L FC using the equation L FC = ((L 2 *T 1 /T 2 )-L 3 )/2, where: L 3 represents a known distance between the pressure change sensing device (16) and a point from which timing of the pressure wave is started; T 1 is the time required for the pressure wave to travel from the timing starting point to the distal end (14) of the fluid conduit (10) and back to the pressure change sensing device; and T 2 is the time required for the pressure wave to travel through a portion of the system (26) of known length L 2 .

The apparatus also includes a generally tubular second member (86) having a second opening (96) formed through a sidewall portion thereof, a third inner side surface, a second radially enlarged outer side surface, and a third radially reduced outer side surface, the second opening providing fluid communication between the third inner side surface and the third outer side surface. The second member (86) is axially slidably disposed within the first member (16,18,20), and the second member (86) is axially rotatable within the first member (16,18,20). A ratchet (122) selectively permits axial displacement of the first member (16,18,20) relative to the second member (86). A predetermined pressure differential across the mandrel is utilized to configure the valve in its open and closed configurations.

摘要： An acoustic impulse gun (10) and associated methods of transmitting signals to equipment positioned in a subterranean well permits the signals to be transmitted in a safe, economical, convenient and efficient manner. The acoustic impulse gun (10) includes an accumulator (12), which is momentarily placed in fluid communication with the well when fluid pressure is applied to a device (20) interconnected between the accumulator (12) and the well. The device (20) includes a shuttle (32) which displaces relative to an inlet port (16) in fluid communication with the accumulator (12), and a discharge port (18) in fluid communication with the well. Fluid pressure is applied to the device (20) in a pattern by a signal control system, thereby causing the shuttle (32) to successively and rapidly permit fluid pressure pulses to be applied to the well.

摘要： A downhole current generator (34) generates power in a wellbore and includes a power section (36) and a generator section (38). The power section (36) has a sleeve (44) slidably disposed within a housing (42) which oscillates in response to the application of fluid pressure to the current generator (34). A piston (48) is slidably attached to the sleeve (44) and oscillates relative to the sleeve (44) and the housing (42). The piston (87) extends longitudinally into the generator section (38) and has a plurality of magnets (78) attached thereto which oscillate with the piston (48). Wire coil sections (82) are fixed relative to the housing of the generator section (38) and are positioned between the oscillating magnets (78) such that a current is induced in the wire coil sections (82) upon oscillation of the magnets (78)
