Description
Technical Field
The utility model belongs to sealing device, concretely relates to liquid hole sealing device is annotated to tub in pit.
Background
CO2+O2Neutral leaching uranium well site processes require the injection of a leaching agent into the well due toO2The solubility increases with increasing pressure, so the injection pipe needs to be lowered into the injection well below 400 meters. Along with the increase of injection pressure, the injection wellhead often shows the leakage sign, and in order to prevent the leakage of the orifice, the orifice sealing method plays a key role.
Along with the production, in order to reduce the workload of the liquid injection pipe and the air pipe under the condition of hole washing, the liquid injection pipe in the well is replaced by the air pipe, so that the hole opening sealing device also has the function of discharging hole washing water.
In the prior art, a rubber pad is added at the sealing position of the hole, and in the using process, along with the change of pressure, the sealing performance of the rubber pad is reduced, and leakage occurs again after a long time, so that a liquid injection hole sealing device is needed to be researched and designed.
SUMMERY OF THE UTILITY MODEL
