Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] refer to Figure 1-5 , a kind of oil pipe oil drainer, comprises casing 1, and oil pipe 2 is arranged in casing pipe 1, and oil drain port 15 is opened on the surface of oil pipe 2, and oil drain device outside oil drain port 15 is arranged on the outside of oil pipe 2, and oil drain The device includes a sealing tube 9 sleeved outside the oil drain port 15. The sealing tube 9 is sleeved outside the oil pipe 2. The sealing tube 9 can block the oil drain port 15. When the sealing tube 9 blocks the oil drain port 15, At this moment, the oil drain port 15 is in a relatively sealed state, and the oil in the oil pipe 2 will not be discharged through the oil drain port 15. The port 15 is staggered, and now the oil flows out along the oil drain port 15 to realize the emptying of the oil.

[0025] The outer casing of the oil pipe 2 is provided with a d...

Abstract

The invention provides an oil pipe oil drain, which relates to the technical field of oil drains, and includes a casing, an oil pipe is arranged in the casing, an oil drain is opened on the surface of the oil pipe, and an outer casing of the oil pipe is provided with an oil drain outside the oil drain. An oil drain, the oil drain includes a sealing pipe sleeved outside the oil drain port, the outer casing of the oil pipe is provided with a driving pipe located on one side of the sealing pipe, and an annular driving chamber is opened in the driving pipe, and the annular driving An annular driving piston is slidably connected in the chamber, and a connecting ring is fixedly connected to the side wall of the annular driving piston. A first spring is elastically connected between the annular drive piston and the annular drive chamber, a limit channel is opened on the side wall of the drive tube, and a first limit member for limiting the position of the annular drive piston is arranged in the limit channel. The invention solves the problem of how to quickly and stably discharge the oil in the oil pipe.

Description

technical field [0001] The invention relates to the technical field of oil drains, in particular to an oil pipe oil drain. Background technique [0002] Extending the rod-shaped oil pipe into the oil well is a common form of oil production. The oil pipe is limited by the anchor, and the crude oil in the oil well is pumped out through the oil pipe to realize the extraction of crude oil. When the oil pipe needs to be taken out, the oil is drained The device releases the crude oil in the oil pipe to prevent the crude oil from leaking to the ground and causing environmental pollution. [0003] The common oil unloading methods are roughly divided into rotary type and percussion type. Among them, the percussion type needs to throw objects into the casing of the oil well to break the hollow oil unloading bolt to achieve the purpose of oil unloading. This method has poor adaptability, and The broken bolts remain in the oil well, which will affect the subsequent oil production. The ...
