Method of and apparatus for completing a well

摘要

A completion apparatus for completing a wellbore includes a tool to alternatively open and close a throughbore; a tool to alternatively open and close an annulus between the outer surface of the completion and the inner surface of the wellbore; a tool to alternatively provide and prevent a fluid circulation route from the throughbore of the completion to the annulus; and at least one signal receiver and processing tool capable of decoding signals received. The apparatus is run into the well bore, the throughbore is closed and the fluid pressure in the tubing is increased to pressure test the completion; the annulus is closed and a fluid circulation route is provided from the throughbore to the annulus and fluid is circulated through the production tubing into the annulus and back to surface. The fluid circulation route is then closed and the throughbore is opened.

主权项

1. An apparatus comprising:
a downhole barrier tool to alternatively open and close a throughbore of the apparatus; a downhole packer tool to alternatively open and close an annulus defined between the outer surface of the apparatus and the inner surface of a wellbore; a downhole circulation tool to alternatively provide and prevent a fluid circulation route between the throughbore and the annulus above the downhole packer tool; a downhole signal receiver and processing tool that decodes wireless signals received to operate at least one of the downhole barrier tool, the downhole packer tool, and the downhole circulation tool; and wherein the circulation tool is located below the signal receiver and processing tool, and both the packer tool and the barrier tool are located below the circulation tool.
