Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Please see Figures 1-4 As shown, the embodiments of this utility model include:

[0019] A metal stamping plate for the inner tube of an oil sand control filter screen includes a stamping plate body 1. The stamping plate body 1 is rolled in the width direction and formed by welding multiple ends to form an inner tube. The inner tube is formed by spiral welding, which effectively improves the pressure rating of the inner tube.

[0020] The stamped plate body 1 is provided with a stamped protrusion 2 and a stamped bridge 3 formed by stamping.

[0021] The stamping protrusion 2 is elliptical in shape on the stamping plate body 1. The bottom to the top of the stamping protrusion 2 is inclined from the outside to the inside. The top of the stamping protrusion 2 is parallel to the stamping plate body 1. The top and bottom connecting sides of the stamping protrusion 2 are both arc-shaped. The elliptical structure of the stamping protrusion 2 increases the contact area with the base pipe, making the inner pipe more firmly and stably fixed, reducing the time of operators when pressing the pipe, and improving the stability of the product when going down into the well.

[0022] The stamping protrusion 2 is located in the middle of the width direction of the stamping plate body 1, and there are multiple stamping protrusions 2 distributed at equal intervals along the length direction of the stamping plate body 1. In this application, there are 4 stamping protrusions 2, which effectively ensures the stress and stable fixation of the inner tube formed by the stamping plate body 1.

[0023] Multiple stamping bridges 3 are arranged laterally and distributed in an array at equal intervals on both sides of the stamping protrusion 2. The bottom to top of the connecting ends on both sides of the stamping bridge 3 is inclined from the outside to the inside. The connecting ends on both sides and the top of the stamping bridge 3 are arc-shaped. The top of the stamping bridge 3 is parallel to the stamping plate body 1. Each of the stamping bridges 3 has a bridge hole 4 formed on the stamping plate body 1. The stamping protrusion 2, the stamping bridges 3, and the bridge holes 4 are arranged parallel to each other and inclined at 22° to the width direction of the stamping plate body 1. Figure 2 The tilt angle α in the middle.

[0024] In this application, the stamped bridge 3 is provided in 6 rows, and the stamped protrusions and stamped bridges are provided in corresponding quantities according to the required dimensions in the length direction. The opening ratio is controlled by controlling the gap between the bridge holes 4 and the opening size of the bridge holes 4, thereby achieving the effect of controlling the filtration volume. The bridge holes 4 are stamped at a certain angle, which can reduce the probability of impurities clogging the bridge holes 4 during filtration to a certain extent.
