Abstract

The corrosion of the casing near a downhole pump suction port is common in some domestic oilfields, and it has a serious impact on the stable production of the oilfield. In order to study the corrosion mechanism, we have designed and manufactured a dynamic simulation test device for the corrosion of the casing near the downhole pump suction port. The device consists of a single plunger pump and a tube and casing strings in line with the site structure to simulate the intermittent production mode of the pump as well as the fluid flow state near the pump inlet adequately, and the corrosion velocity measurement can be made and the corrosion behavior can be studied under different temperatures, CO2 partial pressures, and velocities to provide important data for the casing materials. The test results show that the flow rate and flow pattern of the corrosive medium near the oil pump suction port are the main factors of casing-leakage, and CO2 local corrosion is the main way, which is in accordance with the casing damage status.

Key words： corrosion; pump suction port; corrosion rate
