The high-density punching screen is composed of a central pipe, a high-density punching sleeve and a stainless steel ring. It has the characteristics of precise and controllable porosity, large flow area, high overall strength and strong deformation resistance, excellent corrosion resistance, high reliability, etc.
Product performance features:
High density punching seam filter sleeve, punching seam can be along the axis of the pipe body, using straight seam welding; Unique spiral distribution of punching seam, formed by spiral welding, significantly improve the strength of filter sleeve. In the local external extrusion, under the action of external force, the gap is reduced or closed to ensure the reliability of sand control. Using precision punching technology, the opening of the stainless steel punching filter sleeve is on the side to reduce the direct erosion effect of the sand layer against the screen tube. The processing range of punching gap is between 0.20mm and 0.7mm. The uniformity of the punching seam gap can be guaranteed within the range of machining error of 0.015mm to ensure the requirements of filtering accuracy. Using HIGH-DENSITY punching technology, the effective opening slit length is 3-5 times that of the common slit pipe, and 2-3 times that of the common slit screen pipe. Central tube unique spiral cloth hole
The central pipe of the high-density sluicing screen adopts standard oil and casing, and the central pipe adopts spiral drilling form, which reduces the opening area of the cross section of the pipe body, and ensures the overall flow area of the pipe body, so that the strength of the central pipe can be retained to the maximum extent. Formation sand is held out of the perforation screen, and oil, gas or water from the formation passes through the perforation gap and into the screen through the drilling hole. Approaches to sand control. Excellent anticorrosion performance of the center pipe using API standard casing or tubing, high-density perforation filter sleeve using 304 stainless steel material. For special requirements of H2S, CO2, and high Cl- Wells, corrosion resistant casing or tubing can be used for the center line. The screen resists acid, alkali and salt corrosion.
Scope of application:
The high-density perforation screen can be used for various oil, gas and water Wells in casing and open hole completions such as vertical, deviated and horizontal Wells. It can be used as sand control string alone or in combination with packing.
Cangzhou Shenlong Pipe has mature production equipment and technology, strong technical force, complete testing equipment, perfect quality assurance system, passed the ISO9001:2000 quality management system and the American Petroleum Institute API-5CT standard certification, can produce a variety of steel, a variety of thread types of tubing, casing, table sleeve, couplings and joints, And a number of wire wound screen pipe production line, can process 60.30mm ~ 508mm different specifications and different geological requirements of sand control pipe.
