The invention discloses a wellhead technological module for a gas recovery well, a gas recovery well joint exploitation system, and a method adopting the gas recovery well joint exploitation system, and belongs to the field of natural gas production. The wellhead technological module comprises at least one throttling gas production device and at least one non-throttling gas production device, wherein each non-throttling gas production device of the at least one non-throttling gas production device is communicated with partial or all throttling gas production devices of the at least one throttling gas production device; the gas collected by the non-throttling gas production device is subjected to downhole choke through the throttling gas production device; the throttling gas production device is provided with a downhole flow controller. The wellhead technological module for the gas recovery well, the gas recovery well joint exploitation system, and the method adopting the gas recovery well joint exploitation system, provided by the invention, can effectively reduce land application, equipment investment and construction cost, and can reduce manual investment during operation to reduce the production cost. As a jacket heater and a matched self gas consumption module are not needed for throttling pressure reduction and heating thermal insulation, energy consumption is reduced, and energy conservation and emission reduction are realized.
Description
technical field [0001] The invention relates to the field of natural gas recovery, in particular to a wellhead process module for gas production wells, a combined production system for gas production wells and a method for using the same. Background technique [0002] As a clean energy, natural gas is widely used in industries and households. Natural gas is buried underground in the gas field. It needs to be collected from the formation to the ground through the gas extraction system, and then transported to the natural gas stations in various cities through pipelines, and then the natural gas stations will transport the natural gas to thousands of households for people to use. [0003] At present, the downhole throttling process is mostly used in newly built cluster well group stations or single well stations in gas fields. There are usually two or more gas production wells in a cluster well group station, and downhole restrictors are installed in each gas production well ...
