Background
In the oil gas production process, as the oil collecting pipeline is influenced by the characteristics of the transmission medium and the environment, the pipeline is internally and externally corroded, and the pipeline generates leakage points and oil gas leakage due to long-time corrosion and erosion. The conventional method is to stop the pipeline, cut off the pipeline flow medium by using valves at the front and rear ends of the pipeline, and perform manual electric welding to weld and stop the leakage. The oil collection line is also referred to as an oil and gas conduit.
The difficulty before welding and plugging is to ensure that a transmission medium cannot be stored in a pipeline, so that some pipelines need to be replaced by water or air, the difficulty is increased for plugging, meanwhile, due to the reason that a pipeline control valve is not tight and the like, the pipeline is accompanied by oil, gas and water during plugging, potential safety hazards are formed, the plugging leakage point is too long, and the oil and gas production is severely restricted.

sealing rubber rings are respectively arranged in the two sealing rubber ring annular cavities, two groups of sealing connectors are positioned on two sides of the middle connecting pipe and are oppositely arranged, the oil collecting pipeline penetrates through the sealing rubber rings in the fixed pressing covers, two ends of the middle connecting pipe are respectively screwed in the connecting screw holes of the two fixed pressing covers, two ports of the middle connecting pipe are contacted with ports of the oil collecting pipeline at two ends, and a sealing rubber gasket is arranged between the port of the middle connecting pipe and the port of the oil collecting pipeline; and pressure-resistant and corrosion-resistant chemical sealant is injected into the annular cavity of the sealant ring.
The pressure-resistant corrosion-resistant chemical sealant is HT-150 corrosion-resistant sealant (navigation state-150).
The utility model discloses a use:
after the oil collecting pipeline has a leak point, manually cutting the oil collecting pipeline, taking down a leak point pipe section, and cleaning and polishing the left oil collecting pipeline; pressing the sealing rubber ring into a sealing rubber ring cavity in the fixed gland; sleeving the sealing connector on the oil collecting pipeline, wherein two sides of the sealing connector are respectively provided with one group; pressing the sealing rubber gasket into the inner cavity of the fixed gland; rotating the fixed glands, respectively screwing two ends of the middle connecting pipe into the connecting holes of the two fixed glands, and compacting the middle connecting pipe and the sealing rubber gasket; the middle connecting pipe and the oil collecting pipeline are effectively and mechanically plugged;
after mechanical plugging is finished, injecting pressure-resistant and corrosion-resistant chemical sealant into the glue injection cavity of the fixed gland through the one-way glue injection nozzle and the first glue injection hole; and filling the gap in the sealed connector with chemical sealant, and forming a plugging effect after the chemical sealant is solidified. The pressure-resistant corrosion-resistant chemical sealant can be HT-150 corrosion-resistant sealant (navigation state-150).
The utility model has the advantages that:
utilize mechanical seal and chemical seal to carry out effectual sealed, utilize sealed cushion to produce radial pressure, and the soft interference fit of sealed rubber ring and the pipeline of fixed gland, the sealed clearance that compresses tightly to utilize withstand voltage corrosion-resistant sealed glue to carry out chemical shutoff, and then solve the interior problem such as having the raffinate of pipeline, realize that the oil gas pipeline need not be fired just can safe shutoff construction.
