Patent ID: 8707498

Claim:
A multifunctional cleaning tool for cleaning tubular, the cleaning tool comprising: a main body comprising a first end and a second end, an inlet proximate to the first end, and one or more first outlets disposed in the second end; a propulsion relief assembly proximate to the second end, the propulsion relief assembly comprising: a flow bore fluidly connected to the inlet, wherein the flow bore has a first flow bore end proximate to the inlet and a second flow bore end proximate the second end of the main body; one or more second outlets disposed in the second end of the main body, and a restrictor disposed at the second flow bore end, wherein the restrictor has an actuation pressure, and the restrictor is configured to prevent flow out of the one or more second outlets at fluid pressures below the actuation pressure; and wherein: at a first fluid pressure, below the actuation pressure, the cleaning tool is configured to move the tool through the tubular, and provide flow out the one or more first outlets, while the restrictor prevents flow out of the one or more second outlets, and at a second fluid pressure, above the actuation pressure, the cleaning tool is configured to provide flow out of the one or more first outlets and the one or more second outlets.
