Embodiment Construction
[0011] The drill collar thread cleaning system of the present invention is mainly composed of a ground circulating pool 1, a constant temperature water tank 2, an automatic control system 3, a high-pressure pump unit 4, an external thread cleaning system 5, an internal thread cleaning system 6, and a ground guide rail 7. The system has two high-pressure pump sets 4, which respectively provide the high-pressure water flow required for cleaning the internal thread cleaning system 6 and the external thread cleaning system 5. The high-pressure pump set 4 is equipped with a heating system. Wherein, the internal thread cleaning system 6 is divided into two parts, 2 motors 8 and a high-scattering nozzle 9, which control the advance, retreat and rotation of the cleaning nozzle. The external thread cleaning system 5 is divided into two parts, 2 motors 8 for controlling the advance, retreat and rotation of the cleaning nozzle, and two parts of the spray nozzle 10 . The automatic contr...

The invention relates to a drill collar thread cleaning system. The drill collar thread cleaning system comprises a ground circulating water pool, a constant-temperature water tank, an automatic control cabinet, a high-pressure pump assembly, an external thread cleaning system, an internal thread cleaning system, a ground guide rail and the like. Due to the uniform application of a water jet principle, the internal and external threads of a drill collar can be cleaned, and automatic control is achieved; after the drill collar is cleaned, corrosion damage to the threads caused by harmful substances, a drilling fluid and other dirt can be effectively reduced, the service life of the drill collar is prolonged, the probability of downhole drilling accidents is reduced, the difficulty and the cost for inspecting the threads of the drill collar are reduced, and the inspecting quality is improved.
Description
technical field [0001] The invention relates to a drill collar thread cleaning system. Background technique [0002] During the use of the drill collar at the drilling site, due to the harmful substances in the formation water and the physical and chemical effects of the drilling fluid, the drill collar thread suffers from serious fouling corrosion. If it is not cleaned in time, it will not only reduce the service life of the drill collar, but also It will increase the probability of downhole drilling tool accidents. , The dirt on the drill collar thread brings difficulty to the thread inspection, and reduces the inspection quality and efficiency at the same time. In addition, during drill collar inspection and thread repair, mud and other dirt on drill collar threads can easily generate dust, which not only endangers the health of workers, but also accelerates the wear and tear of testing equipment and turning machine tools. Contents of the invention [0003] The ob...
