Claims14
A wellbore debris removal apparatus comprising:
- a crossover sub having a first sub end and a second sub end, wherein the crossover sub includes at least one slotted mechanism and includes a fluid passageway extending from the first sub end to the second sub end, and wherein the crossover sub includes at least one detent pin;
- and
- a debris removal tube having at least one lug and a tube end to be placed in the crossover sub such that the debris removal tube is locked to the crossover sub via the at least one lug engaging with the at least one slotted mechanism of the crossover sub, wherein the at least one detent pin interacts with a corresponding hole on the debris removal tube when the debris removal tube is locked to the crossover sub.
A well system comprising:
- a conveyance to be positioned in a wellbore;
- a downhole debris removal apparatus to be deployed down into the wellbore via the conveyance, wherein the downhole debris removal apparatus comprises,
- a crossover sub having a first sub end and a second sub end, wherein the crossover sub includes at least one slotted mechanism and includes a fluid passageway extending from the first sub end to the second sub end, and wherein the crossover sub includes at least one detent pin;
- and
- a debris removal tube having at least one lug and a tube end to be placed in the crossover sub such that the debris removal tube is locked to the crossover sub via the at least one lug engaging with the at least one slotted mechanism of the crossover sub, wherein the one or more detent pins interact with a corresponding hole on the debris removal tube when the debris removal tube is locked to the crossover sub;
- a downhole tubular to be positioned in the wellbore and configured to be engaged with the crossover sub and to surround the debris removal tube;
- and
- a venturi device coupled to the downhole debris removal apparatus, the venturi device configured to provide fluid circulation through the downhole debris removal apparatus.
