摘要： Improvements in down-hole mud actuated hammers are disclosed. According to its broadest aspect the invention is a down-hole mud actuated hammer for use in a drill string, which includes a housing with an upper end having means for connecting to the drill string. A throat is located within the housing which throat includes a main flow passage to allow high pressure drilling mud to pass therethrough. A piston is provided which is adapted to move axially within the housing means to thereby reciprocate between an up position and a down position. The piston is moved between the up and down position by a minor portion of the high pressure mud which portion passes from the main flow passage into at least one piston actuating chamber. This minor portion of mud is exhausted from the piston actuating chamber to a low pressure region out of the housing without being returned to the main flow passage.

摘要： A method for remotely managing downhole power consumption in a downhole network system is disclosed. The method comprises the steps of monitoring an activation state for each of a plurality of individually activatable electrically-powered modules in a downhole device and determining an optimal activation state for each module according to system demands. The activation state of each module may be selected from the group consisting of activated or deactivated. The method further comprises the step of transmitting a power state switching instruction from a top-hole processing element to a downhole power-consumption state controller over the downhole network. The method also includes the step of switching the selected electrically-powered modules according to the determined optimal activation states.

摘要： A system for a redundant star network is disclosed. The system consists of a control hub, one or more backup hubs, and at least one peripheral device (PD), the peripheral device comprising a housing having at least one selectable side transparent or opaque to radio frequency (RF) transmissions while the remaining sides are opaque to RF transmissions. The control hub controls the PD, for example by controlling how the PD operates under certain conditions. The PD includes a long-range, wireless transceiver and a microcontroller, which includes instructions for periodically testing, via test signals, whether the control hub is functional. In the case that the control hub does not respond to the test signals, the PD includes instructions for switching control of the PD to the backup hub, which also stores control instructions for the PD, similar to the control hub.
