Embodiment Construction
[0024] The detailed description and technical content of the present invention are described below with the accompanying drawings, but the accompanying drawings are only provided for reference and description, and are not intended to limit the present invention.
[0025] according to Figure 1-3 , a device for cleaning residues in a drill pipe after tripping out, comprising three parts: a propulsion assembly, a cleaning assembly, and a recovery device. Among them, the propulsion assembly is composed of winch 5, horizontal slideway 6, and double-wheel fixed pulley block 7; the cleaning assembly is composed of outer hose 9 and cleaning head 10; the recovery device is composed of waste liquid recovery pool 12, water pump 13 And connecting conduit 14 constitutes.
[0026] Such as figure 2 As shown, the outer hose 9 is composed of an inner water hose 20 and an inner air hose 21.
[0027] Such as image 3 As shown, the cleaning head 10 is composed of four parts: a reducing pipe...

The invention discloses a device for cleaning residues in a drill rod after the drill rod is pulled out. The device is characterized in that the device comprises a propulsion assembly and a cleaning assembly; the propulsion assembly comprises a winch, a horizontal slideway and a two-wheeled fixed pulley; the cleaning assembly comprises an external flexible pipe and a cleaning head; the horizontal slideway is arranged at the upper end of a derrick; the winch is arranged at the lower end of the derrick; one end of the external flexible pipe is wound on the winch; and the other end of the external flexible pipe goes round the two-wheeled fixed pulley and then is connected with the cleaning head. The device further comprises a recovery device; the recovery device comprises a waste liquid recovery pool, a water pump, a connecting duct and an evacuation pool that are connected sequentially, wherein the waste liquid recovery pool is used for storing waste liquid after the cleaning head cleans the drill rod. The pollution problem caused by the fact that the drill rod stays on a drill floor surface after the drill rod is pulled out and liquid mixtures like drilling liquid is remained on the drill floor surface due to the self weight is solved, and the device overcomes the disadvantages of cleaning by using a manual hand-held hydraulic giant.
Description
technical field [0001] The invention relates to the technology for cleaning the drilling fluid and the like in the drill pipe after tripping out in the field of oil production in oil fields, in particular to a cleaning device for residues in the drill pipe after tripping out. Background technique [0002] In the process of oil exploration and oil field development, drill pipe is one of the key tools in the process of oil drilling. The working environment of the drill pipe is harsh, and at the same time it bears various alternating loads such as large torque, bending moment, and tension, as well as the corrosion and erosion of the drilling fluid. When working fluids such as drilling fluid come into contact with the surface of the drill pipe, scaling will appear, and uneven thickness of carbonate, sulfate, silicate scale, and even hydrocarbons such as wax and asphaltene will be formed on the inner surface of the drill pipe. The existence of these fouling layers will undoubted...
