Multifunctional cleaning tool
A method of cleaning a tubular with a cleaning tool that includes the steps of disposing the cleaning tool in the tubular, the cleaning tool having a main body with a first end, a second end, an inlet, an outlet, and a propulsion relief assembly disposed proximate to the second end. The method further includes the steps of sufficiently pressurizing fluid behind the tubular to propel the cleaning tool along the tubular, and increasing the pressure of the fluid to actuate the propulsion relief assembly, whereby fluid is jetted out the outlet and out of the propulsion relief assembly.
1. 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.
2. The multifunctional cleaning tool of claim 1 further comprising:
a first sleeve sealingly engaged to the main body; and
a first seal cup connected to the first sleeve.
3. The multifunctional cleaning tool of claim 1 further comprising a coupler movingly engaged with the first end, wherein the coupler is configured for connecting other devices to the cleaning tool.
4. The multifunctional cleaning tool of claim 3 , wherein the coupler comprises a finishing neck.
5. The multifunctional cleaning tool of claim 1 , wherein a third fluid pressure removably detaches a piston from the second end forming a bypass flow passage out of the second end.
6. The multifunctional cleaning tool of claim 1 , wherein the cleaning tool is deployed with a tether line.
7. The multifunctional cleaning tool of claim 6 , wherein the connection of the tether line with the cleaning tool has a first pre-determined break point, wherein a movable piston frangibly connected with the tool has a second pre-determined break point, and wherein the first pre-determined break point is greater than the second pre-determined break point.
8. The multifunctional cleaning tool of claim 1 , further comprising an internal mandrel connected to the main body, wherein the flow bore extends through the internal mandrel, and the internal mandrel comprises one or more channels fluidly coupling the inlet to the flow bore.
9. The multifunctional cleaning tool of claim 1 , wherein the restrictor is a ball positioned in a ball seat.
10. The multifunctional cleaning tool of claim 1 , further comprising an energizer disposed against the restrictor, the energizer being adjustable to control the actuation pressure of the restrictor.
