摘要： A downhole steering tool is disclosed. The steering tool includes a rotatable shaft, a substantially non-rotating tool body deployed about the shaft, and a plurality of force application members deployed on the steering tool body. The steering tool further includes a bendable section deployed in the steering tool body. The bendable section is disposed to bend preferentially relative to the steering tool body under an applied bending load. The use of a steering tool body having a bendable section tends to advantageously reduce bending stresses in the steering tool body during use. Moreover, tools embodying this invention may be suitable for higher dogleg severity applications.

摘要： A steering tool for use in a well bore is disclosed. The tool includes at least one extendable and retractable blade deployed thereon. The blade is elastically spring biased radially inwards towards the tool such that upon removal of an actuating force, the blade retracts. In exemplary embodiments, the blade includes at least one spring-like, elastically deformable member disposed to elastically spring bias the blade. The spring-like member may include first and second elongated leg portions located on opposing sides of a sprung hairpin portion. Tools embodying this invention may be advantageous for small diameter applications.

摘要： A downhole tool for use in a well bore is provided. The tool includes a tool body and at least one elongated sprung member deployed on an outer surface thereof. The sprung member is configured to lie in a rest position substantially parallel to the outer surface and further includes at least one movable end that is movable with respect to the tool body. The tool further includes an actuation module deployed on the tool body. The actuation module is operably engaged with the sprung member, and disposed, upon actuation, to deflect said movable end thereof away from the rest position. Displacement of the movable end of the sprung member causes elastic spring biasing of the sprung member via bending thereof. The biasing urges the sprung member to return to the rest position upon de-actuation of the actuation module.

摘要： A formation fluid sampling tool including at least one sample tank mounted in a tool collar. The tool collar includes a through bore and is disposed to be operatively coupled with a drill string such that each sample tank may receive a correspondingly preselected formation fluid sample without removing the drill string from a well bore. At least one of the sample tanks further includes an internal fluid separator movably disposed therein. The separator separates a sample chamber from a pressure balancing chamber in the sample tank. The pressure balancing chamber is disposed to be in fluid communication with drilling fluid exterior thereto. The sampling tool further includes a sample inlet port connected to the sample chamber by an inlet passageway.

摘要： Within a single envelope or housing, this full-function valve integrates all of the emergency and service requirements of a tandem axle air brake system for heavy duty truck semi-trailers, thereby decreasing complexity and cost and enhancing safety, reliability and operating capability while also satisfying applicable Federal Regulations. The housing encloses a spring brake valve module, a relay valve module and a biased one-way pressure protection valve, all interconnected to meet operating requirements, while preventing non-intentional spring brake engagement, foreclosing trailer movement without adequate service brake capability and optionally providing anti-compounding protection.

摘要： A method and apparatus for maintaining the single phase integrity of a deep well formation sample that is removed to the surface comprises a vacuum jacket insulated single working cylinder divided by two free pistons into three variable volume chambers. The intermediate chamber is pre-charged with a fixed quantity of high pressure gas. Wellbore fluid freely admitted to one end chamber bears against one free piston to further compress the gas. The formation sample is pumped into the other end chamber to first, displace the wellbore fluid from the first end chamber and, sequentially, to further compress the gas to preserve the sample phase state upon removal to the surface.

摘要： A microprocessor 1 is described which includes a direct memory access (DMA) circuitry 143. DMA 143 is interconnected with a program memory 23 and a data memory 22 and is operational to transfer data to or from these memories. DMA 143 is interconnected with a peripheral bus 110 and thereby to various peripherals internal to microprocessor 1. DMA 143 is also interconnected with an external memory interface 103 and thereby to various external memory circuits and peripherals external to microprocessor 1. An auxiliary channel control circuitry 160 provides DMA transfers by interacting with a peripheral such as host port 150 which has its own address generation circuitry. DMA 143 provides frame synchronization for triggering a frame transfer, or group of transfers. DMA 143 is auto-initialized through registers. DMA action complete pins DMAC0-3 indicate DMA status to external devices. DMA 143 allows for local variability of transfer rates in a split channel mode of operation by allowing a transmit channel to get ahead of a corresponding receive channel by a preselected number of data words.

摘要： Embodiments of the present invention generally relate to extendable cutting tools for use in a wellbore. In one embodiment, a tool for use in a wellbore includes a tubular body having a bore therethrough, an opening through a wall thereof, and a connector at each longitudinal end thereof; and an arm. The arm is pivotally connected to a first piston and rotationally coupled to the body, is disposed in the opening in a retracted position, and is movable to an extended position where an outer surface of the arm extends outward past an outer surface of the body. The tool further includes the first piston. The first piston is disposed in the body bore, has a bore therethrough, and is operable to move the arm from the retracted position to the extended position in response to fluid pressure in the piston bore exceeding fluid pressure in the opening. The tool further includes a lock operable to retain the first piston in the retracted position; and a second piston operably coupled to the lock.
