    摘要: A valve for communication of a measurement while drilling system includes a first structure having a central portion and one or more elongate portions radially extending from the central portion, and a second structure having one or more portions which substantially bound a central orifice region and one or more elongate orifice regions radially extending from the central orifice region. At least one of the first structure and the second structure is configured to be rotated about a rotation axis to produce a relative rotation between the first structure and the second structure such that a flow path through which mud can flow varies as the at least one of the first structure and the second structure rotates about the rotation axis. The central portion has a maximum inscribed circle encircling the rotation axis and having a first radius and the central orifice region has a maximum inscribed circle encircling the rotation axis and having a second radius greater than the first radius.

    摘要: A reciprocating mud pulser system comprising a poppet (103) and a stationary valve assembly (25) with axial flow passages (109). The poppet (103) reciprocates close to the valve assembly, blocking the flow through the valve assembly and generating oscillating pressure pulses. The poppet (103) passes through two zero speed positions per cycle, enabling rapid changes in signal phase, frequency, and/or amplitude thereby facilitating enhanced data encoding like ASK, PSK or FSK . The poppet (103) is driven by a linear electric motor (104) disposed in a lubricant filled housing (108). The housing to shaft seal consists of bellows (107). A force balance spring (105) is used to offset the hydraulic forces on the poppet (103). A bypass poppet (160) is used to adjust the differential pressure across the valve assembly.

    摘要: A system is disclosed for generating and transmitting data signals to the surface of the earth while drilling a borehole, the system operating by generating pressure pulses in the drilling fluid filling the drill string. The system is designed to maximize signal strength while minimizing the probability of jamming by drilling fluid particulates. The system uses a rotary valve modulator consisting of a stator with flow orifices through which drilling fluid flows, and a rotor which rotates with respect to the stator thereby opening and restricting flow through the orifices and thereby generating pressure pulses. The flow orifices with the stator in a "closed" position are configured to reduce jamming, and to simultaneously minimize flow area in order to maximize signal strength. This is accomplished by imparting a shear to the fluid flow through the modulator, and minimizing the aspect ratio and maximizing the minimum principal dimension of the closed flow area. A preferred embodiment and three alternate embodiments of the modulator are disclosed.
