  • In this paper, the method of calculating liquid level using power chart was studied. We selected some test wells in the Tahe oilfield, and compared the accuracy of liquid level calculation with different methods. For those wells with normal power chart, stable working system and water content, alternating load linear regression method is recommended. This method can be influenced by load, working system and water content. As a result, the wells with abnormal power chart, changing water content, frequently-adjusting working system and abnormal pumping are not suitable for the alternating load linear regression method.
