Oiling and cleaning device for oil well short pipe, and operation method thereof

Abstract

The invention discloses an oiling and cleaning device for an oil well short pipe, and an operation method thereof. The oiling and cleaning device for the oil well short pipe comprises a bottom plate,a middle plate, a horizontal screw rod, guide rods, an upper plate, a push air cylinder, a vertical screw rod and an oiling rod, wherein the horizontal screw rod is horizontally arranged on the bottomplate; T-shaped guide rails are arranged on the top part of the bottom plate in parallel; the middle plate is clamped and embedded into the T-shaped guide rails; the guide rods movably penetrate through the upper plate; the upper plate sleeves on the vertical screw rod and is in threaded connection with the vertical screw rod; the push air cylinder is horizontally arranged on the top part of theupper plate; and an output rod of the push air cylinder is fixedly connected with the oiling rod pointing at the oil well short pipe. According to the oiling and cleaning device for the oil well shortpipe, and the operation method thereof, the push air cylinder pushes the oiling rod and an oiling block stained with diesel oil to be inserted into the oil well short pipe back and forth in a reciprocating way and completely penetrate out, so that an inner wall of the oil well short pipe can be oiled so as to be prevented from getting rusty, inner scrap iron impurities are cleared up, directly manual oiling and cleaning are replaced, a large amount of physical strength is saved, and the oiling and cleaning efficiency is improved.

Description

technical field [0001] The invention relates to a mechanical device for oiling and removing impurities for short oil well pipes, in particular to an oiling and removing impurities device for short oil well pipes and an operation method thereof. Background technique [0002] Oil well pipe is the basic casing, oil pipe and drill string components (drill pipe, drill collar, kelly, etc.) of the petroleum industry, collectively referred to as oil well pipe. Oil well pipe is an important part widely used in the oil drilling industry, and its performance is directly related to the success of drilling operations. [0003] Oil well short pipes with a length of 1-2 meters are also used during oil drilling. Now the processing of oil well short pipes will use lathes to thread both ends of short oil well pipes. There will be some iron in the process of threading. If the iron filings are not removed, once the iron filings are brought into the oil well, it will cause irreversible conseque...

Problems solved by technology

[0003] Oil well short pipes with a length of 1-2 meters are also used during oil drilling. Now the processing of oil well short pipes will use lathes to thread both ends of short oil well pipes. There will be some iron in the process of threading. If the iron filings are not removed, once the iron filings are brought into the oil well, it will cause irreversible consequences, and the inner wall of the short oil well pipe will also rust. If it is not oiled in time, it will also Affect the normal use of oil well short pipe

[0004] At present, manual operation is still used for the oiling and lubrication of short oil well pipes. Manually hold a rod-shaped object, tie a rag to one end to form a rag ball, dip it in diesel oil, manually insert the rod-shaped object into the short oil well pipe, and transport it back and forth several times. , the rags stained with diesel oil lubricate the inner wall of the short oil well pipe, and at the same time push out the iron filings inside the short oil well pipe. Since the resistance between the rags and the rusty short oil well pipe is relatively large, it is necessary to use manual direct oiling to remove Miscellaneous is very strenuous, and the arm is sore after several operations, which consumes a lot of energy and is less efficient
