P110 casing plays an important role in well operation. They protect wells from shallow and shallow layers of wells, and also support oil and gas transportation and drilling in oil and gas wells. Support the weight of wellhead and other layers to prevent collapse. And to ensure well drilling, well completion of good operation, to ensure that the pipeline can well pump oil wells, gas to the surface.


As the lifeline of oil well operation, oil casing should have high quality requirements. Because, if the pipeline is damaged under special reasons, it may directly lead to the reduction of production of oil wells, or even lead to the direct abandonment of exploration wells. Therefore, there are many requirements for the selection of casing. The selection should be based on different geology and underground pressure. It is suggested that when purchasing casing, regular production of ordinary casing should be purchased, and the casing should remain intact under the combined forces of tension, pressure, bending and torsion. Don't look for cheaper ones. Although geology is different everywhere, all underground pressures are generally bad. So a good casing is your best choice.


(1) How to reduce the erosion of sand to coal seam.
High-precision stamping technology is used to improve the performance of the opening counter punch of the filter tube.


(2) How to ensure the reliability of sand control.
Let part of the external force of the casing be extruded, so that the external force is under pressure, so that the gap is reduced or reduced. If the casing is punched along the axis in the casing, the straight seam welding can be used.
