Application of high-pressure automatic control flow regulators in gaseous media
Thread Content
For the secondary development of oil fields, water injection or dilution is used to extract oil from heavy oil wells. Currently, both diluted oil and natural gas are being injected. In the past, for liquid media such as water and oil, high-pressure automatic flow control regulators were used for measurement and regulation; now that natural gas, a gaseous medium, is to be injected, can high-pressure automatic flow control regulators still be used? Are there any situations with precedents of successful application? What level of control precision can be achieved? Operating conditions: Design pressure of 25 MPa, operating pressure less than 20 MPa; natural gas flow rate range of 0–300 Nm3/h; normal temperature; pipe diameter of DN65. I would appreciate any further advice from everyone!
It is recommended to consult the manufacturer’s technical staff
It is estimated that even with such products, the accuracy will not be high; volumetric flow measurement definitely involves issues related to temperature and pressure compensation. Therefore, it is recommended to use a flow meter in combination with a control valve. If there is no control system available, a control box can be installed on-site to achieve the same purpose.
