深井滤水管,复合筛管性能特点:
1、更高的过滤精度:由于绕丝筛管采用V型大开口设计,使过滤精度面积更为精密,更好的起到了防砂的作用。
2、极佳的整体强度和抗变形能力:内部由基管支撑,外部根据需要可增加外保护套加强保护,钻孔基管的整体强度比标准的套管/油管 仅下降2~3%,具有足够的整体强度抵抗地层的挤压变形。即使局部变形时,受压部位的缝隙也不增大,防砂可靠性高。
3、更多的选择:外层筛管材质可为不锈钢或低碳钢,可根据用户实际需求自行选择材质。
4、高密度缝隙、低流动阻力缝隙密度是普通割缝筛管的3~5倍,流动阻力低,有利于提高油气产量。
5、良好的工艺性,实现了高效率、低成本、大规模生产
Performance Characteristics of Composite Screen Pipe in Deep Well filter tube;
1. Higher filtration precision: As the wire-wound sieve tube adopts V-shaped large opening design, the filtration precision area is more precise and plays a better role in sand control.
2. Excellent overall strength and deformation resistance: the inner part is supported by the base pipe, and the outer protective sleeve can be added to strengthen the protection according to needs. The overall strength of the drilled base pipe is only 2-3% lower than that of the standard casing/oil pipe, which has sufficient overall strength to resist the extrusion deformation of the formation. Even if it is deformed locally, the gap at the pressure part will not increase and the sand control reliability is high.
3. More choices: The outer screen can be made of stainless steel or low carbon steel, which can be selected according to the actual needs of users.
4. The gap density of high-density gap and low flow resistance is 3 ~ 5 times higher than that of common slotted screen pipe, and the flow resistance is low, which is conducive to improving oil and gas production.
5. Good manufacturability, realizing high efficiency, low cost and large-scale production.
