More Information
Summary:The invention provides a method and a device for acquiring a characteristic curve of a rod-pumped well underground system. The method includes: using an underground lifting system below a polished rod as a whole, and giving parameters of the rod-pumped well underground system; acquiring the characteristic curve of a pump inlet and outlet pressure difference related to actual displacement of a pump, according to the parameters of the rod-pumped well underground system; further, acquiring a characteristic curve of the pump inlet and outlet pressure difference related to power of the rod-pumped well underground system and acquiring a characteristic curve of the pump inlet and outlet pressure difference related to efficiency of the rod-pumped well underground system.
