摘要： Downhole assemblies including a plurality of tubular members extendable within a wellbore and defining a through bore. A telemetry device is positioned within a wall of one of the plurality of tubular members and has a secondary flow path defined therethrough and a valve element engageable with a valve seat provided at an upper end of the secondary flow path. The secondary flow path extends between an inlet and an outlet, both of which fluidly communicate with the through bore and are defined in the one of the plurality of tubular members. A flow restrictor is located within the through bore and is axially positioned between the inlet and the outlet of the secondary flow path. The valve element is actuatable to control fluid flow through the secondary flow path to selectively generate a fluid pressure pulse.

摘要： A fluid pressure pulse generating apparatus including a pulser assembly and a fluid pressure pulse generator and methods of using the fluid pressure pulse generating apparatus. The pulser assembly comprises a motor, a sensor for detecting rotation of the motor, a driveshaft rotationally coupled to the motor, and processing and motor control equipment communicative with the motor and the sensor. The fluid pressure pulse generator is coupled with the driveshaft. The sensor provides an indication of the amount of rotation of the motor and this information can be processed by the processing and motor control equipment to determine the position of the driveshaft and to control rotation of the driveshaft based on a predetermined rotational relationship between the driveshaft and the motor.

摘要： A method of operating a dual pulse height fluid pressure pulse generator of a downhole measurement-while-drilling telemetry tool, the pulse generator operable to flow a drilling fluid in a full flow configuration to produce no pressure pulse, a reduced flow configuration to produce a high amplitude pressure pulse and an intermediate flow configuration to produce a low amplitude pressure pulse, the method comprising: (a) operating the pulse generator to produce the no pressure pulse, the high amplitude pressure pulse and the low amplitude pressure pulse and measuring the pressures of the no pressure pulse, high amplitude pressure pulse and low amplitude pressure pulse; (b) determining an amplitude of the high amplitude pressure pulse and an amplitude of the low amplitude pressure pulse from the measured pressures; (c) comparing the determined amplitudes to a low amplitude reference pressure and a high amplitude reference pressure; and (d) operating the pulse generator between the full and intermediate flow configurations in a low amplitude pulse mode to transmit a telemetry signal to surface only when the determined amplitude of the low amplitude pressure pulse is above the low amplitude reference pressure; or, operating the pulse generator between the full and reduced flow configurations in a high amplitude pulse mode to transmit a telemetry signal to surface only when the determined amplitude of the high amplitude pressure pulse is below the high amplitude reference pressure.

摘要： A pressure pulse generator to generate pressure signals in drilling fluid for transmission to surface comprising: an outer housing (100) having an inlet (9) and an outlet for supply to the drilling assembly (59); a control element (10) slidably mounted in the housing (100) for opening and closing said inlet (9), said element being operative to generate a pressure pulses when it closes; a control passage (26, 27, 28) extending through the element (10) and closable by a valve element (36) arranged to be exposed to the pressure in the passage; and an actuator assembly (13, 14, 15, 17, 19, 21, 35, 36, 37) connected to the control element (10). The control element moves upon activation (10) relative to the inlet to generate a pulse. When deactivated, it blocks the flow through the passage (26, 27, 28) so that all of the fluid bypasses via the inlet.

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.
