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： A downhole tool (32) comprises a tool housing (34) defining a central bore (35) and including a fluid port (20), and a valve member (40) mounted within the housing (34) and being moveable from a closed position in which the fluid port (20) is blocked to an open position in which the fluid port (20) is opened. The tool (32) further comprises a catching arrangement (41) mounted within the housing (34) and comprising one or more radially moveable seat members (106), and being configurable from a free configuration in which the seat members (106) permit an object (48) to pass through the tool (32), to a catching configuration in which the seat members (106) catch an object (48) passing through the tool (32). The valve member (40) comprises an axially extending shroud (94) which extends into the catching arrangement (41) from one axial end thereof such that an end region of the catching arrangement (41) sits radially outside of the valve member shroud (94) and isolated from the central bore (35).
