Coiled tubing packer system

摘要

A wellbore monitoring system comprising a length of tubing defining an axial flowbore, two or more data conduits extending within the axial flowbore of the coiled tubing, two or more sensors, each of the two or more sensors configured to measure a wellbore parameter and to communicate data indicative of the measured wellbore parameter via one of the two or more data conduits, and two or more deployable tubular packers, each of the deployable tubular packers disposed within the axial flowbore of the tubing, wherein each of the deployable tubular packers is selectively secured within the axial flowbore of the tubing, and wherein the two deployable tubular packers provide fluid isolation between a first region of the axial flowbore, a second region of the axial flowbore, and a third region of the axial flowbore.

1. A wellbore monitoring system comprising:
a coiled tubing defining an axial flowbore and selectively positionable within a wellbore; two or more data conduits extending within the axial flowbore; two or more sensors, each of the two or more sensors configured to measure a wellbore parameter and to communicate data indicative of the measured wellbore parameter via one of the two or more data conduits; and two or more tubular packers disposed within the axial flowbore, each of the tubular packers having a radially expandable sealing element and a locking system, each of the tubular packers operable in a deployable first state in which the sealing element is contracted and the tubular packer is movable within the axial flowbore, each of the tubular packers further operable in a locked second state in which the sealing element is radially expanded into sealing engagement with an interior wall surface of the axial flowbore, the tubular packer is fixed within the axial flowbore, and the locking system mechanically prevents contraction of the sealing element; wherein the two tubular packers provide fluid isolation between a first region of the axial flowbore, a second region of the axial flowbore, and a third region of the axial flowbore.
