REMOTE PRESSURE READOUT WHILE DEPLOYING AND UNDEPLOYING COILED TUBING AND OTHER WELL TOOLS

摘要

A well tool has a pressure sensor disposed in an interior space. The pressure sensor has at least one sensing element estimating a pressure parameter of a fluid in the interior space and a transponder configured to transmit radio frequency (RF) signals representative of the estimated pressure parameter. A data retrieval module receives the RF signals transmitted by the transmitter.

主权项

1. An apparatus for estimating pressure at a surface location above a wellbore drilled in an earthen formation, comprising:
a drill string configured to be conveyed along the wellbore; a bottomhole assembly (BHA) connected to the drill string, the BHA including a bore flowing fluid between the surface and an annulus surrounding the BHA; a pressure sensor disposed along the BHA, the pressure sensor having at least one sensing element estimating a pressure parameter of a fluid in the BHA bore; a transponder disposed along the BHA, the transponder being configured to transmit radio frequency (RF) signals representative of the estimated pressure parameter, the transponder being further configured to transmit the RF signals at the surface location; and a data retrieval module positioned at the surface location and configured to receive the RF signals transmitted by the transmitter.
