Abstract

A pressure leak-blocking tool for a gathering pipeline is applied to pressure leakage blocking of the gathering pipeline of an oil field. The tool is characterized in that two ends of a transverse plate (1) are provided with through holes respectively provided with a stud in a penetrating mode, the lower end and the upper end of each stud are respectively connected with a lower nut and an upper nut, a central screw rod is connected with a screw hole in the middle portion of the transverse plate, the top of the central screw rod is provided with two back nuts, a sealing box is sleeved in the middle portion of the central screw rod, the lower end of the sealing box is provided with an inner thread, the lower end of the sealing box is connected with a sleeve barrel in a threaded mode, and the upper end and the lower end of the sleeve barrel are respectively provided with an outer thread. A decompression valve is connected with a decompression pipe welded on the wall of the sleeve barrel, and the lower end of the central screw rod is connected with a plug in the threaded mode. The tool has the advantage that the success rate of the pressure leakage blocking is more than 95 percent. The tool can block all oil-steal gates between four decimeters and one and a half inches. The tool can achieve leakage blocking, and is free of decompression, well suspension and shut-down. The whole soldering process takes 20-30 minutes.

Description

Gathering line leak repairing tool with pressure
Technical field
The utility model relates to the oil gathering and transportation pipelines technical field, and particularly the device of a kind of gathering line mending-leakage with pressure is a kind of gathering line leak repairing tool with pressure.
Background technique
At present, oil gathering and transportation pipelines is a lot, the lawless person is rampant in gathering line dress valve boring stolen, had a strong impact on the daily production management of oil well, be mainly manifested in the following aspects: 1, the lawless person is when gathering line boring stolen, have rapidity, chronicity, disguise, cause the crude oil loss huge.2, during the gathering line mending-leakage, stopping transportation, stop well, pressure release directly affects crude output.3, reclaim that the workload of landing oil is large, time-consuming, effort.4, there are serious potential safety hazard and environmental pollution.5, frequently stop the well mending-leakage and strengthened the well maintenance work difficulty.6, increase employee's amount of labour, cause routine work to lag behind.
The model utility content
The purpose of this utility model is: provide a kind of gathering line leak repairing tool with pressure, can realize not pressure release when mending-leakage, not stop well, non-stopping transportation.
The technical solution adopted in the utility model is: gathering line leak repairing tool with pressure comprises transverse slat, stud bolt, upper cap nut, lower nut, middle screw rod, sealing case, sleeve, Decompression valves and plug.It is characterized in that: there is through hole at the two ends of transverse slat, are installed with respectively a stud bolt in the through hole at transverse slat two ends, and the lower nut that is threaded in the lower end of stud bolt is welded on lower nut on the outer wall of gathering line during use.The upper cap nut that has been threaded in the upper end of stud bolt, the height of upper cap nut control transverse slat during use.At the middle part of transverse slat a screw is arranged, the through hole center line at center line of bolt hole and transverse slat two ends is in same plane; Be connected with a middle screw rod in the screw at transverse slat middle part, there is outside thread the upper end of middle screw rod, and two backrest nuts are arranged at the top of middle screw rod; At the middle part of middle screw rod cover a sealing case, sealing case being arranged is that cylindrical has center hole, and there is internal thread the sealing case lower end, the lower end of the sealing case sleeve that is threaded, and sleeve is cylindric and is enclosed within on the middle screw rod; There is respectively outside thread at the up and down two ends of sleeve; The lower end screw thread of sleeve can be connected on the short circuit head of gathering line.Wall at sleeve is welded with a relief tube, is connected with a Decompression valves at relief tube; The plug that is threaded in the lower end of middle screw rod, described plug upper end is cylindrical, in the upper end of plug center screw is arranged, the lower end of plug is cone shape.
The tapering of described plug is 30 degree.
Be to improve the sealing between sealing case and the middle screw rod outer wall, at the inwall of sealing case center hole seal groove is arranged, seal ring is arranged in seal groove.
The using process of summary gathering line leak repairing tool with pressure: consult Fig. 1.Lower nut 4 is welded on the outer wall of gathering line and two lower nut 4 symmetries, the centre is the leak source (or short circuit head of gathering line) that needs soldering.Assemble gathering line leak repairing tool with pressure; Adjust the position of upper cap nut 3.The lower end outside thread of sleeve 8 is connected on the short circuit head of gathering line.Plug 10 inserts in the short circuit head of gathering line, and the backrest nut of rotation middle screw rod 5 upper ends advances plug 10 downwards.Open Decompression valves 9 and check and have or not leakage phenomenon, namely plug 10 is to seal fully.Plug 10 is ready shutoff half sheet can be welded on around the leak source of gathering line after sealing fully.
The beneficial effects of the utility model: the utility model gathering line leak repairing tool with pressure, implement mending-leakage success rate with pressure more than 95%.But all stolen gates of one-inch half are assigned in shutoff four, check plugging effect by pressure relief valve.Realize not pressure release of mending-leakage, do not stop well, non-stopping transportation, whole welding repair process time spent 20~30min.Stop the environmental pollution that causes because of the emptying pressure release, alleviated workload.Stop the well pressure release when having avoided oil well production and affect output.
