    摘要： A well tool (10) for applying a pulling or a pushing force to an object in an interior of a well bore comprising: a) an inner elongated member (50,62,66); b) an outer elongated member (64); c) a sealed interior defined between the inner elongated member (50,62,66) and the outer elongated member (64); and d) an actuation means (58,62) defined at least partially within the sealed interior; wherein the actuation means (58,62) is adapted to reversibly move the outer elongated member (64) longitudinally over the inner elongated member (50,62,66) and wherein the inner elongated member (50,62,66) and the outer elongated member (64) are arranged such that a volume of the sealed interior occupied by the inner elongated member (50,62,66) remains substantially constant as the inner elongated member (50,62,66) and the outer elongated member (64) move relative to each other.

    摘要： A petroleum well injection system is provided for an intervention cable with a well tool ran into or out of a well during a well operation. The system includes a blow out valve BOP connected to a well head at a well, a lock chamber at the BOP arranged to contain the well tool before and after the well operation, an injector for the intervention cable, with drive belts driven by an electric motor, and a sensor for measuring the injector force or the tension that the drive belts applies to the intervention cable, a guide arch at the injector, wherein the intervention cable runs taut over the guide arch to a first end of the closed bending restrictor channels, a guide arch load cell arranged to measure the backward tension between an intervention cable the first end of the bending restrictor channel, and wherein the other end of the bending restrictor channel is connected to a drum frame with a motor running a drum for the intervention cable.

    摘要： A drilling tool comprising an electrical motor (6) driving a first shaft (7); a pump (8) driven by the motor (6) for pumping well fluid in through an inlet (9) and out through an outlet (10); a gear (11) driven by the first shaft (7) extending through the pump for reducing rotation of a second shaft; and a drilling head (14) having bits (15) and at least one drilling head fluid channel and being driven by the second shaft, the outlet (10) of the pump being fluidly connected with the fluid channel to pump well fluid out through the fluid channel. The gear (11) is arranged in a gear housing (17) arranged in a tool housing (18) defining a gear fluid channel providing fluid communication between the pump and the drilling head fluid channel to prevent well fluid from entering the gear.

    摘要： A system and method in accordance with the invention communicator remotely with remotely controllable down hole tools in a well bore at a drilling installation. At the surface, high energy pressure impulses directed into the tubing or the annulus, or both, being at a level to propagate through an interface between very different impedances zones, such as an upper level gas zone and a lower level of mobile fluid media extending down into the desired downhole location. The pressure impulses, provided by directionally gating along the longitudinal confining path a pressure impulse initially having sharp leading and trailing edges, reach the downhole location as physical perturbations forming a discernible pattern that can be detected by one or more energy responsive transducers. With combinations of these signals, one of a number of separate control devices can be remotely actuated. The system avoids the need for physical or electrical connections and concurrently greatly reduces the likelihood of accidental operation.
