Problems solved by technology

[0003] In the prior art, the plunger gas lift drainage gas recovery system is generally installed, and the energy of the plunger gas lift mainly comes from the high-pressure gas stored in the casing pipe; through the plunger gas lift drainage gas recovery, the bottom hole fluid can be effectively Excluded, but at present, technically, the judgment or measurement of the plunger lifting the liquid column has always been in a blank state

Abstract

The present invention discloses a plunger control system for a well, and relates to the technical field of natural gas devices. The plunger control system employs devices such as a control header, anarrival sensor, a pneumatic film valve, a solenoid valve and an ACF two-phase flow flowmeter to integrally improve a current well plunger control system to achieve the accurate determination of the liquid slug, through adoption of the ACF two-phase flow flowmeter, single-well aerogenesis and liquid production capacity are effectively measured, the gaseous phase measurement precision can reach up to 1%, and the liquid phase measurement precision can reach up to 10%, and therefore, through accurate measurement of gas and liquid, the production process and the system can be better optimized.

Description

technical field [0001] The invention belongs to the technical field of natural gas equipment and relates to a wellhead device, in particular to a control system that provides a new technology approach for the stable production of complex gas fields with low pressure, low production, low abundance and strong heterogeneity. Background technique [0002] With the development of gas fields, the number of managed single wells is increasing year by year, and the number of water-producing gas wells is increasing, and the water production is gradually increasing. Due to the low single-well production of gas wells and poor liquid-carrying capacity, it is easy to cause fluid accumulation at the bottom of the well, which will adversely affect the production of gas wells, and the work of drainage and gas recovery has become increasingly prominent. [0003] In the prior art, the plunger gas lift drainage gas recovery system is generally installed, and the energy of the plunger gas lift m...
