Analysis of advantages of laser processing petroleum screen pipe

At present, the wire wound screen is widely used. The manufacturing method of this kind of screen pipe is as follows: the steel wire with certain section is wound on the metal liner pipe which is evenly distributed on the surrounding screen rod or opening, and a certain gap is reserved as the screen hole.

Although this manufacturing method has been used by many manufacturers in China, there are some problems when the screen pipe goes into the well, especially when the high pressure passes through the bend section of the high angle well or horizontal well, it will inevitably collide, squeeze and rub with the well wall or casing, which is easy to cause the screen pipe damage or crack deformation, and reduce the completion quality and sand control effect In view of the disadvantages of the wire wound screen, the slotted screen tube with the integration of pipe and seam appears.

Because of its superior performance and low price, slotted screen pipe has been highly valued and widely used in major oilfields. It can be seen that the emergence of slotted screen pipe provides material conditions for the development of horizontal wells and sidetracking wells and oil production in high sand reservoirs.
