Description

Technical Field

[0001] The invention relates to the technical field of oil drilling, in particular to a separator with an anti-corrosion structure used in deep-sea oil drilling. Background Art

[0002] During deep-sea oil drilling, the wind blowing from the sea to the ground carries more moisture and humidity than the wind blowing from the ground. What we generally refer to as corrosiveness refers to stone objects such as buildings and rocks, or metal objects such as ships and containers. The moisture in the sea breeze can react physically or chemically with the stone, and undergo redox reactions with the metal;

[0003] The oil separator with publication number CN201821237017.9 can effectively separate gas and liquid in wells with large gas volume, prevent a large amount of gas from entering the pump barrel to affect pump efficiency and reduce single well production. Through the slag discharge port structure, it can effectively deposit solid impurities such as sand in the gas-liquid process, avoiding pump jams, blockages and other faults.

[0004] During the use of current separators, sea breeze and water vapor can easily cause corrosion to the pipes and joints of the separators. During the circulation and processing of oil, the bottom and joints of the separators are prone to leakage. At the same time, the single anti-corrosion structure cannot protect and replace the important parts of the separators, resulting in the only way to perform anti-corrosion treatment on the surface of the separators manually. The fixed cover structure needs to be fixed by welding, but the offshore oil production device has a small area, and the welding process consumes a lot of time and labor intensity, resulting in a greatly reduced life of the separators during use.

[0005] The separator is used for separation, buffering and metering of multiple phases such as oil, gas, water, and mud. There are a lot of impurities inside the newly mined crude oil, which need to be screened and filtered through a static filtering structure. However, the separator lacks a cleaning structure for the filter device. As a result, during regular cleaning, the filter device is mainly flushed with a water gun, but some impurities embedded in the gaps are prone to clogging and cannot be fully cleaned.

[0006] Therefore, we propose a separator with an anti-corrosion structure for deep-sea oil drilling in order to solve the above-mentioned problems. Summary of the invention
