The difference in appearance between technical casing and surface casing
Technical casing and oil casing are both types of casing used in the petroleum industry, but their specific uses are different.
Technical casing is mainly used in drilling, cementing and production processes. Its main function is to support the well wall and prevent well wall collapse and leakage. It can also seal the well head to prevent pressure leakage at the well head. Therefore, technical casing plays a vital role in the oil extraction process.
Oil casing is mainly used to transport oil and gas and prevent well wall collapse. After the oil and gas production is completed, the technical casing is removed, while the oil casing remains in the well pipe as a pipeline for transporting oil, natural gas and other resources. It needs to be resistant to corrosion, withstand high pressure, etc., and it also needs to ensure the smoothness and sealing of the inside of the pipeline.
