Abstract

The invention discloses an intelligent throttling system and a method for a gas well, and belongs to the field of development and gas production of the gas well. The intelligent throttling system comprises a first pressure sensor, a controller, an adjusting device, and a production valve, wherein the production valve is arranged at a wellhead of the gas well. The first pressure sensor, the controller and the adjusting device are electrically connected in sequence, and lowered into the upper portion of an inner producing layer of the gas well along with a production pipe string. The productionvalve is used to produce a pressure signal with a preset range of variation at the wellhead of the gas well. The first pressure sensor is used to receive the pressure signal and transmit the pressuresignal to the controller. The controller is used to receive and process the pressure signal and obtain the corresponding production adjustment instruction. The regulating device is used to regulate agas production rate of the gas well according to the production adjustment instruction. The specific pressure signal is produced at the wellhead by the production valve, so that the intelligent throttling can be realized by using the adjusting device to control the gas production capacity of the gas well under the control of the controller. The intelligent throttling system and the method for thegas well are simple in operation and convenient to implement, and are facilitate to go down to the well.

Description

technical field [0001] The invention relates to the field of gas well development and production, in particular to a gas well intelligent throttling system and method. Background technique [0002] In the process of natural gas extraction and production, it is necessary to control the gas production of gas wells to achieve the purpose of stable production. During throttling production, it is generally used to install a throttle device with a throttle nozzle in the gas well to control the gas production. The mouth diameter of the throttle nozzle of the throttle cannot be adjusted in real time. To achieve different levels of throttling and production adjustment functions, it is necessary to replace the throttle nozzle with different diameters, which is labor-intensive. Therefore, it is necessary to provide a real-time adjustment Gas well intelligent throttling system and method for gas production. [0003] The prior art provides such a gas well intelligent throttling system ...
