Test packer and method for use

摘要

A downhole tool having a throughbore is disclosed for use in a tubular located in a wellbore. The downhole tool has a sealing element configured to seal an annulus between the downhole tool and an inner wall of the tubular; at least one flow path formed in the downhole tool, wherein the flow path is configured to allow fluids in the annulus to flow past the sealing element when the sealing element is in a sealed position; and at least one valve in fluid communication with the flow path and configured to allow the fluids to flow through the flow path in a first direction while preventing the fluids from flowing through the flow path in a second direction. A guard may be installed proximate anchor elements. The guard extends radially beyond an outer diameter of the anchor elements when the anchor elements are in a retracted position.

主权项

1. A method for testing a liner overlap in a wellbore, comprising:
running a downhole tool having an axial throughbore into a tubular in the wellbore to a location proximate the liner overlap; engaging an inner wall of the tubular with a sealing element thereby sealing an annulus between the downhole tool and the tubular; displacing a first fluid in the annulus in a first direction through a bypass flow path in the downhole tool thereby bypassing the engaged sealing element; closing a valve in the bypass flow path, thereby prohibiting fluid flow through the bypass flow path in a second direction, wherein the valve is selected from the group consisting of a check valve and a flapper valve; and pressure testing the liner overlap.
