Overview
Self-propelled oil well casing exhaust control valve is a new product specially designed and developed for the process requirements of casing exhaust. In crude oil production, in order to prevent excessive casing pressure, resulting in low sinking and the phenomenon of “air lock” of pumping pump, manual intermittent casing gas is generally used to ensure the normal production of oil well. In order to save energy and reduce emissions, protect the oil well and prevent the oil well from producing sand and water, the casing pressure needs to be controlled. The device is easy to install and adjustable in line. It is especially suitable for the unstable production pressure difference and needs to adjust the production pressure difference.
