The Great Role of Oil Casing Pipe

In the past, when oil extraction was carried out, simple mechanical tools were used to dig wells, and then oil workers would stand on the side of the well to extract oil and transport the oil by pipeline, which caused great problems for safety and efficiency. It is mainly manifested in the following aspects:

First, the low-level water and soil are easily confused with oil, resulting in no guarantee of the purity of the extracted oil. Second, there are no supports inside the oil mine, so there is a great safety hazard for workers' lives and equipment operations. Under this circumstance, many designers aimed at how to reform the entire production pipeline system of the oil industry, so that the oil casing pipe was born.

Below, I will introduce this piping system and its use in detail:

1. It is precisely that oil casing has so many advantages. More and more oil extraction companies use this set of materials as necessary props for processing and extracting oil. Due to the comparative convenience of assembly, more and more manufacturers choose Go to produce the materials of the monomer, and then the manufacturer buys it for simple assembly.

2. Petroleum casing pipe is a pipeline system for oil extraction, transportation, and solid guarantee. It is mainly used for safe operations underground. If you have been an oil worker and have been in such a working environment, you will understand After the use of oil casing, the entire work site has become extremely strong. In this case, it is easier to achieve a focused and meticulous operation process. Since the birth of the oil casing, countless oil workers will feel that this industry is no longer full of dangers like before.

Oil casing pipe is used for oil well drilling, mainly used to support the well wall during the drilling process and after completion, to ensure the progress of the drilling process and the normal operation of the entire oil well after completion. The following requirements are imposed on the inner and outer surfaces of oil casing pipe:

1. The inner and outer surfaces of the oil casing shall not have folds, hair lines, delamination, cracks, creasing and scarring. These defects should be completely removed, and the depth of removal should not exceed 12.5% of the nominal wall thickness.
2. The outer surface of the coupling shall not have defects such as folding, hairline, delamination, cracks, creasing, and scarring.
3. The surface of the oil casing and coupling thread should be smooth, without burrs, tears and other defects that are sufficient to interrupt the thread and affect the strength and tight connection.

Tips: Petroleum casing pipes can be divided into different steel grades according to the strength of the steel itself, namely J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc. Different well conditions and depths have different steel grades. In corrosive environments, the casing itself is also required to have corrosion resistance, and in places with complex geological conditions, it is also required to have anti-collapse performance.
