Background technique

The oil pumping unit is a kind of equipment for extracting oil. It is commonly known as "kowtow machine" and pressurizes the oil to flow out of the well. When the oil pumping unit strokes up, the oil pipe elastically contracts and moves upward, driving the mechanical unblocking oil extractor to move upward, hitting the sliding sleeve and causing vibration; at the same time, the forward check valve closes, and the reducing piston assembly blocks the oil. When the oil pumping unit lowers During the stroke, the oil pipe elastically stretches and moves downward, driving the mechanical unblocking oil extractor to move downward, hitting the sliding sleeve and causing vibration; at the same time, the reverse one-flow valve is partially closed, and the reducing piston assembly still blocks the annular oil passage of the oil sleeve. , causing a high-pressure area to form in the area below the reverse one-flow valve, and this movement produces a reverse impact force on the oil flow channel in the formation.
