Method and device for intelligently opening and closing well

The invention discloses a method and device for intelligently opening and closing a well, and belongs to the technical field of natural gas exploitation. The method includes the steps of collecting environmental parameters of a gas collecting well, wherein the environmental parameters include one or more of pressure in an oil tube for collecting the gas, pressure between a casing pipe sleeving theoil tube and the oil tube, pressure in a gas conveying pipeline, flow of fluid in the gas conveying pipeline, the valve opening degree of a throttle valve for achieving opening and closure of the gaswell, and the interval time between the current moment and the moment for opening the well or the interval time between the current moment and the moment for closing the well; determining whether ornot the environmental parameters meet the conditions for opening and closing the well under a preset pattern; if the environmental parameters are in accord with the conditions for opening the well under the preset pattern, acco
