When purchasing oil casing, choose a regular company

Oil casing plays an important role in oil well production. They can protect oil wells from damage to shallow gas layers, and can also protect oil and gas transportation and oil and gas well drilling to support wellheads and other layers to prevent collapse. It also ensures the good operation of the entire well after the oil well is drilled and completed, and ensures that the pipeline can pump oil and gas from the well to the surface.

As the lifeline of oil well operations, oil casing puts forward higher requirements for the quality of casing. Because if the pipeline is damaged due to some special reasons, it may directly cause the production of the oil well, or even lead to the direct scrapping of the oil well. Therefore, there are many requirements for the selection of oil casing.

The selection should be purchased based on geological differences and well pressure. When purchasing oil casing, it is recommended to purchase casing produced by regular companies. Under the combined effects of tension, compression, bending and torsion, the regularly produced oil casing is still very complete. Don't be greedy for petty gains. Although the geology is different, the overall pressure in all areas is small, so a good oil casing is your best choice.

So how does oil casing reduce the erosion of coal seams by sand layers? How does it ensure the reliability of sand volume control?

Because the oil casing adopts high-precision stamping process, the opening of the filter tube is displayed on the side. Part of the oil shell is squeezed by external force, and the compressed part is acted upon by external force, thereby reducing the gap.

If the welding seam of the oil casing is along the axial direction of the pipe, straight seam welding can be used.
