The invention provides a remote well natural gas recovery device which mainly comprises a water jacket heater, a gas-liquid separator, a filter, a dehydration device, a reciprocating compressor, a gas charging pillar, a gas generating set and the like, and is characterized in that gas generated from a remote well is heated by a heating furnace, the heated gas enters the gas-liquid separator and the filter for separation and filtering to remove a liquid phase and a solid phase via separation and filtration, the filtered product is dehydrated by a molecular sieve, the dehydrated product enters the reciprocating compressor, the compressed product is pumped into a CNG trailer after being measured by the gas charging pillar to serve as CNG commercial gas for sale; when the CNG trailer containing the recovered gas is driven to a gas gathering station of a gas field, and the recovered gas is pumped into a pipe network again, charged gas enters a by-pass of the dehydration device directly; when the pressure in a well mouth is equal to or higher than 20 MPa, the charged gas enters a by-pass of the compressor directly; fuel gas of the gas generating set and the water jacket heater is supplied through a rear process pipeline of the dehydration device; and the whole set of the remote well natural gas recovery device is mounted on two semi-trailers, and fixedly erected on a well field via a hydraulic jack. The remote well natural gas recovery device is suitable for recovery of scattered natural gas in high-yield or intermittent-production remote wells of different well mouth pressures; the moving, transportation and mounting are convenient and fast; the adaptive capacity is high; and the recovery cost is low.
