Description

Quick plugging device for oil pipeline drilling

technical field

The utility model relates to a fast plugging device for perforating an oil pipeline, which belongs to the technical field of oil field exploitation.

Background technique

For a long time, oil pipelines in oil fields have been damaged by criminals. The thieves quickly drilled holes in the pipelines, installed hidden cards and non-leakage valves, and carried out multiple oil thefts. The pressure of the oil pipeline is high, and it is difficult to block the oil theft valve. The safety risk is high, the maintenance time is long, and the workload is heavy. Inadvertent blockage will cause a large amount of crude oil to leak out, pollute the environment, and cause major economic losses to the oil field.

Contents of the invention

The purpose of the utility model is to provide a fast plugging device for perforating an oil pipeline to prevent the oil from being stolen.

Concrete technical content of the present utility model is as follows:

The occlusion device is composed of occluder and chain press forceps;

Occluder: the pressure rod is inserted into the cylinder through the center hole on the top surface of the sleeve, the cylinder wall is provided with a vent check valve, the cylinder outer wall is provided with connecting threads, and the cylinder is equipped with a pressure rod and a high-pressure oil seal supported by a retaining ring. The bottom end of the pressure rod is connected with a tapered plug;

Chain press pliers: the top of the lifting rod is connected to the handle, the middle of the rod is connected to the skeleton, the bottom is connected to the 360° movable joint and the arc-shaped pressing plate, and the chain is connected to both ends of the skeleton.

The plugging device is used to quickly ban oil stealing valves on oil pipelines in oil fields and seal pipeline breaches. It has the characteristics of no crude oil leakage, no environmental pollution, convenient and fast plugging, and low safety risks, and has a wide range of popularization and use significance. .

Detailed ways

Example:

The embodiment of the utility model is further described with reference to Fig. 1 to 3:

The occlusion device is composed of occluder and chain press forceps;

Occluder: the metal pressure rod 1 is inserted into the cylinder through the center hole on the top surface of the sleeve 4, the cylinder wall is provided with a vent check valve 5, the external wall of the cylinder is provided with a connecting thread, and the cylinder is provided with a sleeve pressure rod 1. The rubber high-pressure oil seal 2 supported by the retaining ring 3 is connected to the wooden tapered plug 6 at the bottom end of the pressure rod 1 .

Chain press pliers: the top of the lifting rod 8 is connected to the handle 7, the middle part of the rod is threaded to the frame 9, the bottom end is connected to the 360 ° movable joint 11 and the rectangular arc-shaped pressing plate 12, and the chain 10 is connected to the two ends of the frame 9.

When the plugging device works, the sleeve 4 of the plugging device is threaded into the oil stealing valve on the oil pipeline, and the tapered plug 6 is pressed into the pipeline breach 13 through the pressure rod 1, and then the sleeve is sealed with the high-pressure oil seal 2 4. To prevent the liquid in the cylinder from flowing out, the sealing effect can be verified by the vent check valve 5. When repairing the welding gap, install the chain-type pressure pliers on the gap, press the prefabricated tile 14 tightly on the gap through the handle 7, the lifting rod 8 and the arc-shaped pressure plate 12, and then press the tile 14 and the pipe 15. welding.
