Chemical corrosion: mainly occurs during the construction process of oil and gas extraction, such as acidification, fracturing, cleaning of pipelines and large tanks, etc.

The conventional sand pump structure is: the pump is located in the middle of the pipe column, with 10-15 sand settling pipes connected to the lower part, and a discharge valve and pen tip at the bottom.

With the continuous development of oil fields, the crude oil in the formation is constantly being extracted, causing the formation pressure to decrease. In order to maintain a certain production capacity, a certain amount of water is injected into the formation to artificially increase its production capacity.

The pumping rod continuously moves back and forth inside the oil pipe, sometimes causing severe wear of the oil pipe or the oil pipe continuously rotating or expanding with the movement of the pumping rod, resulting in severe wear of the outer wall of the oil pipe and the casing.

The packer mainly consists of a setting mechanism, a locking mechanism, a releasing mechanism, a rubber cylinder, and connecting components.

The oil well pump descaling device is installed under the oil well pump drain, fixed above the valve, mainly to prevent oil stains, rust, and other debris from falling into the oil well during the process of lowering the oil well pump string and rod string, as well as dead oil and floating sand from entering the oil well during the pumping process

Petroleum machinery and equipment are relatively common equipment in the petroleum industry, but they may exhibit corrosion during use. So, what are the reasons for corrosion? Below, the editor will briefly introduce relevant knowledge points to you.
