Abstract

The invention relates to a leakage blocking device for a leaking oil well, which is characterized by comprising a sleeve pipe (10), wherein a diverging cone (11) capable of axially sliding along the sleeve pipe is sheathed on the left side of the sleeve pipe (10), a group of fan-shaped blocks (12) in axial arrangement and radial diverging are arranged on the diverging cone (11), the fan-shaped blocks (12) have wedge-shaped inner surfaces matched with corresponding wedge-shaped surfaces of the diverging cone (11), in addition, the two matched wedge-shaped surfaces are in matched connection with chutes through slide blocks in axial arrangement, a pull rod (5) penetrating through the sleeve pipe is arranged in the sleeve pipe (10), the left end of the pull rod (5) is connected with an umbrella-shaped end cover (1), and a shaft coupler (3) which is in matched connection with the left end surface of the diverging cone (11) and can drive the diverging cone (11) to axially move is arranged on the pull rod (5) arranged at the right side of the umbrella-shaped end cover (1). The leakage blocking device for the leaking oil well has the beneficial effects that the whole device is designed on the basis of the expansion principle of an expansion shaft, the leakage position can be fast blocked, a good leakage blocking effect is realized, and the great environment pollution caused by continuous leakage, the energy waste and the economic loss caused by the pollution are avoided.

Description

technical field [0001] The invention relates to an oil leaking oil well plugging device. Background technique [0002] With the continuous expansion of industrial scale and the continuous enhancement of continuous production, the economic losses caused by leakage are becoming more and more serious. Because of the existence of leakage, not only the continuous loss of energy and materials, but also the loss of toxic, harmful and corrosive , Inflammable, explosive, high-temperature, high-pressure various liquid media leak out continuously, causing environmental pollution, causing fire, explosion, poisoning, and personal casualties. An enterprise often shuts down the entire production system due to a small leakage. The problems exposed at the accident disposal site mainly include: frequent leakage accidents of dangerous sources, slow disposal after leakage, outdated disposal methods, slow emergency response, There is no advanced processing device, and the commonly used plugging...
