Abstract
The invention discloses a drilling tool screw thread connector cleaning tool. The drilling tool screw thread connector cleaning tool comprises a male thread spraying cleaning head, a female thread spraying cleaning head and a control handle. The control handle comprises a barrel body and an air inlet control switch. The two ends of the barrel body are connected with the male thread spraying cleaning head and the female thread spraying cleaning head correspondingly. The barrel body is provided with an air inlet connector used for being connected with an air pump pipeline. The air inlet control switch controls airflow to be sprayed from the male thread spraying cleaning head or the female thread spraying cleaning head. The drilling tool screw thread connector cleaning tool is light, convenient and easy to operate; drilling tool screw threads are cleaned through the high-speed airflow, the labor intensity is low, and the cleaning speed is high; in addition, the risk that the screw threads are damaged by manual operation can be avoided, and both the male thread and the female thread can be cleaned; and meanwhile, the male thread spraying cleaning head can be replaced according to the size of the male thread, so that the efficient cleaning effect of the cleaning tool is ensured.
Description
Technical field
The present invention relates to the technical field of oilfield drilling, specifically refer to the instrument in drilling engineering, thread of drilling tool joint being cleaned.
Background technology
Drilling tool is requisite critical component in whole oil/gas drilling operation process, and drill bit can be sent into shaft bottom by it, and provides the effect of the pressure of the drill and power, also plays transmission high speed drilling fluid, the effect of completion fluid.Connection and sealing between drilling tool are to be realized by thread of drilling tool end contact.If drilling well screw thread is not cleaned, it may appear that thread off and the risk of back-off, and some small granules easily make screw thread scratch, final seal failure is even pierced through, cause whole drilling tool to be scrapped, not only extend drilling period and also add operating cost, have a strong impact on working performance.Time more serious, screw thread pierces through that to develop into drilling tool thorn disconnected, makes lower drilling tool fall into well, develops into serious down-hole accident, will be heavy economic losses.According to statistics, during whole drill rod assemblies lost efficacy, losing efficacy and account for 60% at nipple, screw thread integrity is directly connected to the length in the service life of whole drilling tool.Therefore it is necessary screw thread end face is cleaned before drilling tool connects.
The most relatively common drilling tool male and female screw thread cleaning mode has two kinds, and one is to use hydraulic giant to be directly cleaned screw thread；Another kind is to use wire brush to be cleaned thread of drilling tool end face.The former flows directly in drilling tool by the cleanout fluid when cleaning box, polluting drilling fluid makes its performance change, the shale layer position making water sensitivity strong is more prone to cave-in, and the narrow Density Window layer position of high temperature and high speed well and deep well being added to the risk of leakage and well kick, complex situations are dealt with improperly and may be developed into abandoned well；And the latter is likely to be due to misoperation, cut is stayed to make screw thread seal failure at screw thread end face, on wire brush, steel wire blocks lower drilling tool in may falling into drilling rod simultaneously, occurs suppressing pump and the phenomenon of downhole drill instrument blocking inefficacy, and operation is forced to pull out of hole and checks and change with boring instrument.Use wire brush cleaning mode to divide manually and automatically both of which: manual mode time-consumingly long, labor intensity is big and cleaning efficiency and quality low；Electric cleaning pattern is only for the burnisher of pin thread configuration design, it is impossible to be cleaned box, makes that electric cleaning pattern is more difficult to be promoted the use of at situ of drilling well.
Summary of the invention
It is an object of the invention to overcome the deficiency of above-mentioned prior art, it is provided that a kind of simple in construction, the cleaning means of thread of drilling tool joint rapid cleaning can be used this cleaning means, be avoided that the problem that mud contamination and thread of drilling tool damage.
To achieve these goals, the technical solution used in the present invention is: a kind of thread of drilling tool joint cleaning means, it is characterized in that: include pin thread injection cleaning head, box injection cleaning head and joystick, joystick includes that cylinder and air inlet control switch, the two ends of cylinder are connected with pin thread injection cleaning head, box injection cleaning head respectively, being provided with the inlet suction port for connecting air pump pipeline on cylinder, air inlet controls on-off control air-flow and sprays from pin thread injection cleaning head or box injection cleaning head.
Further, described pin thread injection cleaning head is a hollow ring jaggy, and one end of hollow ring is closed, and other end opening and the one end with described cylinder are connected, and offer injection pore on the inwall of hollow ring.A diameter of 1-2mm of described injection pore, pitch of holes is uniformly distributed by 2.5-3cm.The internal diameter of described hollow ring is more than drilling tool pin thread diameter 2-3cm.
Further, described box injection cleaning head is elongated jet blower, diameter 3-5mm at jet blower.
Further, threaded with pin thread injection cleaning head, box injection cleaning head respectively in the two ends of described cylinder.
The present invention also provides for a kind of thread of drilling tool joint cleaning method simple to operation, it uses the thread of drilling tool joint cleaning means of said structure, concrete operations are as follows: first, pin thread is sprayed cleaning head and box injection cleaning head is threadeded with the cylinder two ends of joystick respectively, after being docked with the air pump pipeline on rig floor by inlet suction port again, open air pump switch on rig floor；Secondly, determine that cleaning object is pin thread or box, by corresponding injection cleaning head alignment cleaning object；Finally, control switch by joystick upper air and air-flow is switched to the injection cleaning head ejection of correspondence, until the residue on cleaning object is removed clean.
The invention has the beneficial effects as follows: simple and light, simple to operate, use high velocity air cleaning thread of drilling tool, labor intensity is low, and cleaning speed is fast, and is avoided that manual operation destroys screw thread risk, box also can be cleaned by pin thread, pin thread injection cleaning head can be changed, it is ensured that the efficient cleaning effect of instrument according to pin thread size simultaneously.
It addition, male and female button injection cleaning head is threaded connection with joystick, during damage of components, only need to reinstall new parts after the parts dismounting damaged, labor intensity is little, and has saved cost, is especially suitable for being generalized to the application of each major oil and gas field situ of drilling well.
Accompanying drawing explanation
The present invention is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the thread of drilling tool joint cleaning means of the present invention.
Detailed description of the invention
As shown in Figure 1, one thread of drilling tool joint cleaning means of the present invention, including pin thread injection cleaning head 10, box injection cleaning head 20 and joystick, joystick includes that cylinder 30 and air inlet control switch 31, and the two ends of cylinder 30 are connected with pin thread injection cleaning head 10, box injection cleaning head 20 respectively.Being provided with the inlet suction port 32 for connecting air pump pipeline on cylinder 30, air inlet controls switch 31 control air-flow and sprays from pin thread injection cleaning head 10 or box injection cleaning head 20.In the present embodiment, threaded with pin thread injection cleaning head 10, box injection cleaning head 20 respectively in the two ends of cylinder 30.It is of course also possible to use other connected mode, such as grafting, snap connection.
