Single-well remote control switch well device

The utility model discloses a single-well remote control switch well device applied to the technical field of natural gas well exploitation, which is characterized by mainly consisting of a single-well remote terminal control system, a well head emergent intercepting valve, a single-well flow meter, a pressure transducer and a break valve. The end part of a valve set of a large four way at the lower part of an oil extraction tree is fixed with a sleeve internal pressure speed changer through a flange and a pipeline, a valve set of a small four way at the upper part of the oil extraction tree is connected with a gas collecting pipeline, an oil pipe internal pressure speed changer is fixed on the gas collecting pipeline, and the gas collecting pipeline is sequentially connected with the break valve, the well head emergent intercepting valve and the natural gas flow meter. The well head emergent intercepting valve is connected with the single-well remote terminal control system through leads. The utility model h
