Abstract
The utility model relates to a maintenance auxiliary device in the field of oil exploitation, in particular to a leaking stoppage device for an underground oil-conveying pipe. According to the technical scheme, the leaking stoppage device is characterized in that a hook body larger than a semi-circle is arranged on the outer side wall of the box body, a spring is arranged between the two end openings of the hook body, a hole is formed in the bottom wall of the bottom body, and a rubber cushion is arranged on the lower face of the peripheral bottom wall of the hole. The leaking stoppage device has the advantages that the oil-conveying pipe does need to be lifted above the water surface, maintenance speed is fast, time and labor are saved, well closing time is short, working efficiency is greatly improved, and environment pollution is reduced.
Description
Technical field
The utility model relates to a kind of maintenance aid in field of petroleum exploitation, specifically relates to a kind of Pipeline Under Mother Earth leakage-baffling device.
Background technique
In petroleum production at present and production, at underground water interior conduit corrosion and ageing, pipeline is in water middle punch, cause large-area oil pollution, in maintenance construction, very inconvenience, needs the long period to stop well servicing, conventional method for maintaining is that pipeline must stop conveying crude oil, pipeline is hung out to the water surface, by driving a well again after the mending-leakage of hole, greatly reduce oil production rate.
Model utility content
The purpose of this utility model is exactly the deficiency existing for prior art, provides a kind of rapid-maintenance and without the Pipeline Under Mother Earth leakage-baffling device that pipeline is hung out to the water surface.
Technological scheme: comprise casing, it is characterized in that: the coupler body be greater than semicircle is set on the outer side wall of casing, between the two-port of coupler body, spring is set, on the diapire of casing, hole is set, rubber pad is set below the peripheral bottom wall in hole.
Can also be improved to: a pair of coupler body that is greater than semicircle is set on described casing outer side wall, and a pair of coupler body that is greater than semicircle, on same straight line, arranges spring between the two-port of coupler body.
Can also be improved to: a pair of coupler body that is greater than semicircle is set below the diapire of described casing, and a pair of coupler body that is greater than semicircle, on same straight line, arranges spring between the two-port of coupler body, and respectively in the both sides in hole, rubber pad is set below the peripheral bottom wall in hole.
Beneficial effect: this technology is without transport pipe is hung out to the water surface, and maintenance speed is fast, time saving and energy saving, is mainly that to stop the well time short, has greatly improved working efficiency, has reduced environmental pollution.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the present embodiment, and in figure, 1 is transport pipe.
Embodiment
With reference to accompanying drawing 1, the present embodiment mainly comprises casing 2, and a pair of coupler body 3 that is greater than semicircle is set on casing 2 outer side walls, the a pair of coupler body 3 that is greater than semicircle is on same straight line, spring 4 is set between the two-port of coupler body 3, on the diapire of casing 2, hole is set, rubber pad 5 is set below the peripheral bottom wall in hole.
Operating method: a pair of coupler body 3 that is greater than semicircle is buckled on transport pipe, use spring fastening, under the sealing of rubber pad, water in casing is sealed in casing, and the water in casing is extracted out, and welding machine is aimed to the aging hole of transport pipe seam leakage blinding, then open spring, take out coupler body, complete whole Process of Leaking Stoppage, quick and convenient.
