Our company has designed and developed a large diameter oil pump specifically for oil wells with given casing sizes. The outer diameter of the plunger is larger than the inner bore of the oil pipe, and a larger diameter oil pipe that accommodates the plunger stroke is typically connected to the pump. Additionally, since the plunger cannot pass through the oil pipe, the entire pump body must be lowered down the well along with the oil pipe, and a disconnect device is used to connect the plunger to the pumping rod. For oil pipe leakage operations, either a pump leakage method or a leakage valve can be selected.

Structure: The pump body size is reduced, and a disconnect device is provided.

Features:

1. The large diameter oil pump can operate within oil wells of given casing sizes, enhancing the well’s production capacity.
2. Maintenance operations require lifting the oil pipe.

Standard materials and various heat treatment and surface treatment processes can be utilized to meet the product’s strength, corrosion resistance, and wear resistance requirements based on well conditions.
