摘要:
A method and apparatus for acquiring data representing formation parameters while drilling a wellbore is disclosed. A well is drilled with a drill string having a drill collar that is located above a drill bit. The drill collar includes a sonde section having transmitter/receiver electronics for transmitting a controlling signal having a frequency F and receiving data signals at a frequency 2F. The drill collar is adapted to embed one or more intelligent sensors into the formation laterally beyond the wall of the wellbore. The intelligent sensors have electronically dormant and active modes as commanded by the transmitter/receiver circuitry of the sonde and in the active mode have the capability for acquiring and storing selected formation data such as pressure, temperature, rock permeability, and the capability to transmit the stored data to the transmitter/receiver of the sonde for transmission thereby to surface equipment for processing and display to drilling personnel. As the well is being drilled the sonde electronics can be positioned in selected proximity with a remote sensor and, without tripping the drill string, formation data can be acquired and transmitted to the surface to enable drilling decisions based thereon.
