摘要： Hydraulic pulses are produced each time that a pulse valve interrupts the flow of a pressurized fluid through a conduit. The pulse valve includes an elongate housing having an inlet configured to couple to the conduit to receive the pressurized fluid, and an outlet configured to couple to one or more tools. In the housing, a valve assembly includes a poppet reciprocating between open and closed positions, and a poppet seat, in which the poppet closes to partially block the flow of pressurized fluid through the valve. A bypass passage is configured to connect with a valve actuation vent port such that when the poppet closes the valve actuation pressure is less than the difference between the pressure up stream of the pulse valve and a pilot within the poppet moves between disparate positions to modify fluid paths within the valve. When the valve is open, a relatively lower pressure is produced by a Venturi effect as the fluid flows through a throat in the poppet seat, to provide a differential pressure used to move the pilot and poppet.

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： An apparatus and system for generating pressure pulses for enhancing and completing a well bore within a coiled tubing assembly including: a CT-MWD-FTD tool longitudinally and axially positioned within the center of a main valve assembly including a main valve. The drilling fluid is subsequently split into both an inlet main fluid stream and a pilot fluid stream, wherein the pilot fluid stream subsequently flows such that the pilot fluid recombines with the main flow stream to become a main exit fluid flow. The main exit fluid flow then proceeds toward a motor housing wherein one or more annular pressure sensors measure the pressure of fluid flow with sensors that send signals to a Digital Signal Processor (DSP) that controls flow throttling devices which generate controllable, large, rapid and measurable energy pulses.

摘要： A method of communication between a device located in a borehole and a remote sensor, comprising the steps of: providing a string of a plurality of connected components, one or more vessels running along the string to form a continuous, substantially enclosed fluid path; incorporating a device into the string so that the device is in communication with the fluid path; inserting the string into a borehole so that the device is located below a surface into which the borehole is formed and the fluid path extends from the surface to the device; providing a pressure sensor at or near the surface, the pressure sensor being adapted to sense the pressure of the fluid in the fluid path; substantially filling the fluid path with a pressurised fluid; over a communication period, venting fluid, under the control of the device, from the fluid path to an exterior of the string at or near the device on one or more occasions, so that the resulting decrease in pressure in the fluid in the fluid path can be detected by the pressure sensor; and during the communication period introducing fluid into the fluid path at a rate below 30 gallons/minute [0.113 m
3 /minute].

摘要： A device, method, and system for creating a pressure pulse from drilling fluid within a drill string in a down hole drill collar (29) for enabling measurement-while-drilling. The device and system are designed such that primarily laminar flow exists in the area surrounding the pulser apparatus. The method associated with the reproducible and essentially noise -free pulses occur when a pulser bell is manipulated in an upward and downward direction by a combination of the solenoid activation of a bi-directional poppet (20) to redirect the fluid flow from the pressure reservoir to and from a sliding pressure chamber (26) and associated upper (25) and lower (23) flow connecting channels. The pulse or non-pulse is converted into a digital signal uphole by a pressure transducer in conjunction with a decoding algorithm. It is then displayed to the driller and oilfield operators as useful directional and formation information that help the oilfield operator for uphole decision making regarding directional drilling. Additional pulsers can be added to the tool so that higher data bit rates can be accomplished. These higher data bit rates will provide for more comprehensive data collection thereby reducing drilling costs and optimizing oil field yields. The higher bit rate allows for more sensors that can send additional and improved information uphole without the use of open hole wire line logging which is impossible to accomodate while drilling horizontally.
