摘要： A downhole tractor is provided that includes a housing and a first wheel assembly coupled to the housing that is operable to translate away from the housing in a first direction. The first wheel assembly has a first electric motor, a first wheel, and a first reduction gear assembly coupled between the first electric motor and the first wheel. A second wheel assembly is coupled to the housing and is operable to translate away from the housing in a second direction that is opposite to the first direction. The second wheel assembly has a second electric motor, a second wheel, and a second reduction gear assembly coupled between the second electric motor and the second wheel. A fluid ram is coupled to the first and second wheel assemblies for selectively translating the first and second wheel assemblies toward and away from the housing. A first controller is provided for controlling the flow of current to the first and second electric motors. On-board and surface control systems may be incorporated to permit selective active of the wheels assemblies. In addition, couplings and connectors employing shape-memory materials may be included to secure the tractor to coiled tubing or a wireline.

摘要： A method and apparatus for operating a downhole tool is disclosed. The method involves providing a conduit for the passage of fluid. The conduit includes at least one reader which can read data and is arranged for the passage of fluid. A downhole tool is coupled to the reader and has at least one tag capable of containing data. The tag is moved within the conduit and at least partially through the reader such that the reader can read data from the tag when the tag passes. This enables remote operation of the downhole tool. An antenna is provided for use in a downhole tubular. The antenna comprises a generally cylindrical housing and a coiled conductor located within a portion of the housing and separated therefrom by insulating material. The portion of housing has a greater internal diameter than an external diameter of the coiled conductor.

摘要： A method for downhole communication and an apparatus for remote actuation of a downhole tool is disclosed. The method comprises the steps of: programming at least one tag (20) to emit a radio frequency identification signal in the form of a frequency change in a carrier wave; locating a reader (10) responsive to signals emitted from the at least one tag downhole; moving the at least one tag (20) past the downhole reader (10) such that the downhole reader (10) is capable of reading data from the tag (20) when the tag (20) passes the reader (10); and thereby communicating data from the tag (20) to the reader (10) downhole. Typically, the method includes programming the tag (20) and the reader (10) to communicate data by at least one of the following means: transitions between discrete frequencies; use of specific discrete frequencies; and length of time in which a carrier wave emits a specific frequency in preference to at least one other frequency.

摘要： An apparatus for and a method of transmitting signals from the surface of a well to a location downhole in the well utilize a downhole fluid pressure sensor, a signal processing means located downhole in electrical connection with the pressure sensor and a downhole programmable logic unit capable of counting at least two signals received by the downhole pressure sensor. Typically, signals transmitted from the surface comprise a peak in pressure of downhole fluid located in production tubing run into a well bore and these signals are sensed by the downhole fluid pressure sensor. The logic unit outputs a signal to a tool to be actuated if it receives a number of signals within a particular time period, wherein the logic unit actuates the tool by the frequency of signals received rather than the amplitude of the signals received.

摘要： A system for transmitting hydraulic control signals and hydraulic power to downhole well tools while reducing the number of hydraulic lines installed in the wellbore. Hydraulic control signals can be furnished at relatively lower pressures, and the hydraulic pressure within the line can be selectively increased over a threshold level to provide hydraulic actuation power. The system can provide multiple control paths through a few number of hydraulic lines to provide flexibility and verification of well tool operation. Closed loop hydraulic operation monitors well tool operation, and a combination of pressurized hydraulic lines can provide an operating code for selective downhole well tool control. Four hydraulic lines can provide independent control and actuation of seven well tools, and additional combinations can be constructed.
