Abstract (en)
A downhole tool said tool comprises an inlet (3) for connection to a chemical flow line and an outlet (4) for injection of chemicals from the flow line into a downhole formation, the tool further comprises a plug (47) actuable within the tool for selectively closing off the fluid flow path through the tool to allow for pressure testing of the flow lines without the need to convey test equipment into the production tubing and a method of testing a downhole chemical injection line in an oil well completion comprises the steps of deploying a downhole (1) into the well in the closed position, applying a pressure greater than the operating pressure to the tool, monitoring the pressure within the tool, reducing the pressure to operating values and then subsequently actuating the tool to an open position to allow for injection of chemicals into the well through the tool.
