Downhole Intelligent Throttle For Gas Well

SITAN QZJ-100 downhole intelligent throttle for gas well is the new designed integrated structure, can be used to change the throttle nozzle size. The opening controlling if SITAN QZJ-100 gas well downhole throttle can be in two ways, automatic and manual. The automatic way is to set the experience flow value before the instrument goes down. The flow throttle can adjust the gas nozzle opening degree according to the measured flow rate. The manual method means to control the gas nozzle opening degree through the wireless communication put down. In this way, the problem that the size of the throttle nozzle is difficult to change can be solved, and the size of the throttle nozzle is measured in real time. When the gas well operation system is changed, the flow control can be adjusted by changing the size of the gas nozzle.

 

Features

1. SITAN QZJ-100 gas well downhole intelligent throttle can achieve wireless controlling, changing the opening of the gas nozzle, no need to fish gas nozzle repeatedly, saving lots of labor and mechanical costs;

2. Wireless communication. If downhole history data is needed during production, historical data can be extracted by putting down the communication section to docking;

3. One time construction, without fishing operations, saving a lot of manpower and resources;

4. SITAN QZJ-100 gas well downhole intelligent throttle can be used in inclines or inclinometers that can not be measured in conventional processes.


Composition and working principle

The anchoring and sealing part of the SITAN QZJ-100 gas well downhole intelligent throttle adopts the traditional mechanical throttling mode, the mechanical slip-type anchoring and the sealant cartridge setting. The sealant cartridge is compressed by piston-type to form the setting force.

A control part is installed above the SITAN QZJ-100 gas well downhole intelligent throttle anchoring mechanism to control the size of the throttle orifice. The SITAN QZJ-100 gas well downhole intelligent throttle structure adopts a cone valve structure, and the size of the throttling annular gap is adjusted during the regulation to adjust the control flow rate.
