Technical Field

The utility model relates to a clamp is fixed to the pipeline, especially relates to an oil-water well maintenance can turn to pipeline fixing device with removing, and during oil field oil-water well maintenance operation, the mountable is on retrieving the ground recovery jar of oil, sewage for the solid high-low pressure pipeline of card belongs to oil field oil-water well repair tools technical field.

Background

When the oil-water well of the oil field is maintained, the high-pressure and low-pressure pipelines are required to be fixed on the ground recovery tank for recovering oil and sewage, so that the oil and the sewage are completely discharged into the ground recovery tank, and the ground is prevented from being polluted.

The currently used pipeline fixing clamp hoop is formed by connecting an upper semicircular edge and a lower semicircular edge with a horizontal side lug into an integral slip, like an omega symbol with two side lugs flattened, round holes are formed in proper positions of the two side lugs, and the upper slip and the lower slip are connected and fixed through bolts. The bottom of the lower semicircle is directly welded on the manhole edge of the ground recovery tank for recovering oil and sewage, so the position and the direction of the hoop cannot be changed. Ideally, after the pipeline to be fixed is placed in the slips, the slips are closed and connected through bolts, and then the pipeline can be fixed.

Because the area of an oil field well site is small, the connecting position from a ground high-pressure pipeline to a ground recovery tank is limited, so that the outlet of the high-pressure pipeline and the outlet of the low-pressure pipeline are difficult to align with the manhole of the ground recovery tank, the positions or angles are not aligned, the pipelines cannot be accurately embedded into a fixed hoop, and only can be tied up on the hoop by using iron wires or steel wire ropes; secondly, acid liquor under the injection well is sprayed out from a high-pressure pipeline, and if the acid liquor is sprayed to an operator, personal injury and serious pollution accidents can be caused; thirdly, the friction between the pipeline and the ground recovery tank forms sparks, and if combustible gas such as natural gas is met, serious fire accidents can be caused.
