Role and repair of P110 casing pipe

The P110 casing pipe has played an important role in well operation. They protect the well from the shallow and shallow layers of the well and can also support oil and gas well oil and gas delivery and drilling. Support the weight of the wellhead and other layers to prevent collapse. And to ensure the well drilling, well well after well completion of the well operation, to ensure that the pipeline can be well oil, gas pumped to the ground up.

As the lifeline of oil well operation, petroleum casing should have higher quality requirements. Because, if the pipeline is damaged under a special kind of reason, it will be possible to directly cause the oil well to reduce its production, or even cause the exploration well to be scrapped directly. Therefore, there are many requirements for the selection of casing pipe, the selection should be based on the different geological, underground pressure to the size of the purchase. Proposed in the purchase of casing pipe, the purchase of regular production of regular casing pipe, and in the pull, pressure, bending, torsion and other comprehensive force under the still intact oil casing. Do not seek to be cheaper, although the geology is not the same everywhere, in general all the underground state of stress is not good. So a good oil casing is your best choice.

(1) How to reduce the erosion of the sand to the seam.
The use of high precision punching technology, the filter pipe opening on the performance of the punch on the side.

(2) How to ensure the reliability of sand control.

Let the casing pipe part of the external force squeezed, so that the pressure in the external force, so that the gap to reduce or reduce the gap. If the oil casing of the punch in the tube along the axial direction, you can use straight seam welding.
