Embodiment Construction

[0036] In order to make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] see figure 1 and figure 2 , the invention provides an oil pipe overflow guide, comprising:

[0038] Guide body 100; The guide body 100 comprises:

[0039] first split 10;

[0040] A second split valve 20 that is rotatably connected to the first split valve 10 and can form a circular tube with the first split valve 10;

[0041] at least one drainage tube 30 located on the first sub-lobe 10 and / or the second sub-lobe 20; and

[0042] The handle 40 is arranged at the junction of the first split 10 and the second split 20 .

[0043] In the oil pipe overflow guide provided by the present invention, before the oil pipe is undocked, the guide body 100-100 is clamped by the oil pipe coupling, and the oil pipe coupling is turned to unhook, so as to...

Abstract

The invention discloses an oil pipe overflow guider. The oil pipe overflow guider comprises a guider body (100); the guider body (100) comprises a first split (10), a second split (20), drain pipes (30), and a handle (40); the second split (20) is rotatably connected with the first split (10), and the second split (20) and the first split (10) can enclose to form a circular pipe shape; at least one drain pipes (30) are located at the first split (10) and / or the second split (20); and the handle (40) is arranged at the joint of the first split (10) and the second split (20). In the process of oil pipe hoisting, the oil pipe overflow guider can effectively prevent the environment from being polluted by sump oil and sewage overflow from the inside the oil pipes.

Description

technical field [0001] The invention relates to the technical field of oilfield operations, in particular to an oil pipe overflow guide. Background technique [0002] In order to prevent the overflow liquid in the tubing from polluting the surrounding environment when the tubing is running in the well or when the tubing is pulled up, it is necessary to collect the dirty oil and sewage in the tubing. [0003] At present, there are mainly the following devices for collecting dirty oil and sewage in oil pipes: [0004] The patent document CN201358759Y discloses a dirty oil and sewage collector in the oil pipe for downhole operation. The oil and sewage collector for the oil pipe in the downhole operation is a liquid collection tank with upper and lower joints fixed to communicate with it and a liquid outlet at the lower end. The upper and lower joints and the liquid collection tank are made of symmetrical two half cylinders combined by sealing gaskets. The outer two peripheries...
