Abstract
A system for cementing a tubular member in a well bore includes a cementing plug. The cementing plug includes at least one sensor. The system transmits a value measured by the sensor to a surface location. The system may transmit the value measured by the sensor through a cable connected between the plug and the surface location. Alternatively, the system may transmit the value measured by the sensor acoustically to the surface location.
Claims60
A system for cementing a tubular member in a well bore, which comprises:
- a cementing plug, said cementing plug being generally cylindrical and having an upper surface, a lower surface, and at least one tubular member wall contacting surface, said cementing plug including at least one sensor;
- and,
- means for transmitting a value measured by said at least one sensor to a surface location.
A system for cementing a tubular member in a well bore, which comprises:
- a cementing plug, said cementing plug being generally cylindrical and having an upper surface, a lower surface, and at least one tubular member wall contacting surface, said cementing plug including at least one sensor and a first communications interface coupled to said at least one sensor;
- a second communications interface coupled to said first communications interface;
- and,
- a processor coupled to said second communications interface.
A cementing plug, which comprises:
- a plug body, said plug body being generally cylindrical and having an upper surface, a lower surface, and at least one tubular member wall contacting surface;
- at least one sensor mounted in said plug body;
- and,
- a communications interface coupled to said at least one sensor.
A cementing plug, which comprises:
- a plug body, said plug body being generally cylindrical and having an upper surface, a lower surface, and at least one tubular member wall contacting surface;
- and,
- at least one sensor positioned in said plug body.
A cementing system, which comprises:
- a cementing plug body, said cementing plug body having an upper surface, a lower surface, and at least one wall contacting surface defined by at least one wiper member;
- and,
- at least one sensor positioned in said cementing plug body.
