割缝管
为什么选择tuspipe?
割缝管插槽规格
割缝钢管的插槽尺寸包括插槽的宽度和长度,可根据客户的规格要求定制。直槽或楔形槽的最小槽宽为 0.012 英寸,最大槽宽为 0.25 英寸。
| 1.5 英寸长 | 2.0 至 2.5 英寸长 | 2.5 英寸长 |
|---|---|---|
| 0.012英寸宽 | 0.024 英寸宽 | 0.078 英寸宽 |
| 0.015 英寸宽 | 0.025 英寸宽 | 0.125 英寸宽 |
| 0.016 英寸宽 | 0.038 英寸宽 | 0.250英寸宽 |

| – | 0.058英寸宽 | – |
割缝钢管开槽模式
为适应不同的特性,我们设计了三种不同的槽型布局(如下图所示)。与交错槽和直槽相比,帮槽设计大大提高了衬垫对横向屈曲和坍塌应力的抵抗能力。
交错割缝管
交错的插槽均匀地分布在圆周上,并有一定的偏移。
帮槽式割缝管
帮槽式由分散在四周的许多插槽组成。
直槽割缝管
直槽衬垫的槽柱围绕圆周均匀分布,没有偏移。
割缝钢管的槽型
TUSPIPE 可以根据客户的规格要求激光切割槽,既可以是直槽,也可以是键槽。
- 直式插槽
这种割缝类型垂直于割缝管,从内壁到外壁的直径相同。虽然直槽的建造成本较低,但其防沙效果不如键槽。
- 基石插槽
楔形槽或锥形槽的切割角度较小,内侧比外侧大,可确保进入槽内的任何颗粒都能自由通过而不会堵塞槽口。虽然键石割缝的制造成本比直割缝高,但它消除了因填充割缝管而造成生产损失的危险。
插槽密度
管道的槽密度定义为每英尺管道的槽数。它由管道外表面的开口面积决定。割缝管的开放区域对削弱其防沙能力有重要作用。一般来说,开口面积占总面积的 2% 到 4%。
在确定开阔地面积、割缝宽度和衬垫直径后,可使用以下公式估算每英尺的割缝密度:
N = (12*π*D*C) / (100*W*L)
N 代表槽密度或每英尺的槽数
D 代表衬垫的外径,单位为英寸
C 代表开口面积,百分比
W 代表槽宽,单位为英寸
L 代表槽的长度,单位为英寸
例如,如果 4.5 英寸割缝管的开口面积为 3%,割缝宽度为 0.02 英寸,割缝长度为 1.5 英尺,那么每英尺的割缝数是多少?
根据上述计算,所需的槽数如下所示:
N = (12*π *4.5*3) / (100*0.020*1.5) = 172
注: 这是对直槽或接缝键槽的直接计算。

割缝管的特点
割缝钢管是一种过滤器,可阻挡碎石等大颗粒,允许油气通过。它广泛应用于石油工业。首先,割缝管用于水平井和高粘度储层。第二,蒸汽辅助重力泄油(SAGD)。割缝管广泛用于注水井和生产井之间。它还用于砾石包完井。确保油井的长期稳定生产。
割缝管的应用
割缝管是带孔或槽的井筛,允许流体通过,同时防止沙子和其他微粒通过。它们有多种用途,包括完井、修井和防砂。割缝管可以由钢、不锈钢、铝或塑料制成,并有各种尺寸和缝隙配置。在完井过程中,割缝管用于为流体流动提供通道,防止井筒坍塌。在油井修复中,割缝管可通过创建新井筒或修复受损井筒来提高产量。而在防砂方面,割缝管可用于防止油井产砂。割缝管是石油和天然气生产的重要工具,其应用范围还在不断扩大。
