Intelligent gas well valve adjusting system

Abstract

The invention provides an intelligent gas well valve adjusting system. The intelligent gas well valve adjusting system comprises an existing gas well production data arrangement and analysis module, an intelligent model automatic decision-making and updating module, an abnormal working condition intelligent judgment module and a variable oil nozzle fine adjustment module; the existing gas well production data arrangement and analysis module is used for receiving existing well production data from an in-well sensor device and processing the existing well production data to obtain the arranged existing well production data; the intelligent model automatic decision-making and updating module is used for performing machine learning on the arranged existing well production data, establishing a productivity prediction model and a hydrops prediction model based on a feedforward artificial neural network, and generating an intelligent gas well valve adjusting scheme; the abnormal working condition intelligent judgment module is used for analyzing monitoring data from the in-well sensor device, judging the occurrence of an abnormal working condition, giving an alarm and updating the intelligent gas well valve adjusting scheme; and the variable oil nozzle fine adjustment module is used for automatically adjusting the opening degree of a variable oil nozzle according to an actual working condition of a gas well and an intelligent prediction result of the intelligent model automatic decision-making and updating module.

Description

technical field [0001] The invention relates to the technical field of natural gas exploitation, in particular to an intelligent gas well valve adjustment system. Background technique [0002] As a clean energy source, natural gas is widely used in industrial production and civil life. In the middle and later stages of natural gas well exploitation, the pressure of gas wells in low-pressure gas fields drops rapidly, the production declines sharply, the stable production period is short, the degree of recovery is low, and the gas flow rate decreases, while the liquid carried by the gas The speed drops faster, and the liquid gradually condenses, forming fluid accumulation at the bottom of the well, which increases the proportion of liquid in the well fluid. During the production process of the gas well, the fluid accumulation in the wellbore leads to a decline in the production of the gas well, or even shuts down. Therefore, it is urgent to adopt intelligent management for gas...
