In recent years, the oilfield has entered a period of high water cut oil production, produced liquid water content increased.To increase crude oil production, injection and liquid output should increase, production costs will continue to improve.To this end, the oilfield have taken "control oil" development approaches, plugging water is one of the policy objectives of effective processes.
3TB series profile control and water shutoff pumps, polymer injection pump is suitable for oil extraction process requires injection, profile, blocking, grouting, suitable for high-dose, prolonged, steady voltage profile control and water shutoff technology has wide application in Changqing oilfield, yanchang oilfield.
