Problems solved by technology

The operator’s misoperation is due to the need to lift the oil pipe in the process of lowering the oil pipe and the hard-to-change habit formed over the years, which may cause the oil drain to be opened and drained.
Patent No. 00258996.6 slip type rotary oil drainer, the slips cannot be radially opened and cannot be stuck on the casing, so no oil is drained, since the slips can be radially opened and stuck on the casing, the slips will be stuck after the oil is drained Sometimes the tile cannot be retracted and the pipe string is stuck, causing an accident

Embodiment Construction

[0009] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0010] In the figure: 1 is an inner tube, 2 is a track pin, 3 is a friction mechanism, 4 is a release sleeve, 5 is a locking ball, and 6 is a sealing sleeve. Namely the present invention is made up of inner tube 1, track pin 2, friction mechanism 3, release sleeve 4, lock ball 5, sealing sleeve 6. The friction mechanism 3 is set outside the inner tube 1, and the outer surface of the inner tube 1 has a track groove, and the track groove is divided into an upper track groove C (or a short track groove, Figure 5 shown) and lower track E (or long track slot, Figure 5 As shown), the inner tube 1 and the friction mechanism 3 are connected by the track pin 2, the track pin 2 can move in the track groove on the outer surface of the inner tube 1, the release sleeve 4 is located at the lower part of the friction mechanism 3, and the sealing sleeve 6 is installed in the...

Abstract

This invention relates to an oil drainer, which comprises inner tube, track pin, frictional mechanism, discharging cover, lock ball and sealing sleeve, wherein the frictional mechanism covers on the inner tube connecting through the track pin; the discharging cover is on the lower of the frictional mechanism, and the sealing sleeve is arranged on the lower of the inner tube connecting through lock ball; the discharging cover is outside the sealing sleeve, and its end face is below the lock ball. When draining oil, pulling upwards the drainer, rotating oil pipe, then pulling upwards the drainer again; it can control when draining freely and dose not need instruments and pumping rod. The device will not cause oil leaking.

Description

1. Technical field [0001] The invention relates to an oil lifting pipe drainer for mechanical oil recovery in an oil field. 2. Background technology [0002] Existing oil drainer kind is a lot, and great majority is to borrow the sucker rod in the well to open the oil drain or the ground input tool to open the oil drain. If the sucker rod of these types of drainers breaks off, the sucker rod cannot be lifted out, and oil drainage cannot be realized. For example, the patent No. 96238554.9 is a split-type oil pipe drainer. Its supporting unlocking assembly will contact the oil drain assembly and drain the oil when the oil pipe is lifted up. When the new situation needs to lift the oil pipe, it will cause the drainer to open and drain the oil, making the operation unsuccessful. Patent No. 00247456.5 lifts the oil pipe drainer again, also there is the problem of above-mentioned patent (96238554.9 a kind of split type oil lifter drainer). The operator's misoperation is because...
