割縫篩管適用于出砂粒徑大于0.3mm的出砂井防砂。割縫邊緣垂直度好，切邊潤滑、無毛刺，割縫平均。過流面積大，27/8”篩管300條割縫/1.5m，比同規格油管過流面積大2.4倍。全體舉行功能穩固處置，提升了篩管的腐蝕性及功能，可延伸其井下任務壽命。割縫管采用J55或N80石油套管本體加工，強度好，不易變形。內通徑大，易于舉行管串配置。

割縫篩管是在管壁(bi)上(shang)應用銑(xian)刀在銑(xian)床上(shang)銑(xian)削而(er)(er)成，其縫寬度取決(jue)于(yu)能經過襯管的砂粒粒徑大(da)小，因而(er)(er)，針對不同砂粒，可選擇不同的割縫寬度來(lai)舉行(xing)防砂，從而(er)(er)到(dao)達避免地層(ceng)(ceng)出砂的目的。由于(yu)銑(xian)刀強度的限制，0.3mm以下的割縫寬度難以加工，因而(er)(er)割縫襯管只適用于(yu)中一(yi)粗粒徑油砂儲層(ceng)(ceng)。依據割縫管剖面(mian)來(lai)看，可分為平行(xing)割縫和梯形割縫，目前往(wang)往(wang)采用橫向梯形割縫構造(zao)。

割縫篩管的(de)加(jia)(jia)工(gong)(gong)(gong)(gong)品質(zhi)次要取決于單條割縫的(de)尺(chi)寸精度(du)、縫形規整(zheng)度(du)、縫腔外表粗拙度(du)和耐腐蝕度(du)以及割縫的(de)軸(zhou)向(xiang)散(san)布和周向(xiang)散(san)布精度(du)。激(ji)光(guang)切割與傳統機械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)相比具有(you)加(jia)(jia)工(gong)(gong)(gong)(gong)效率高加(jia)(jia)工(gong)(gong)(gong)(gong)精度(du)高加(jia)(jia)工(gong)(gong)(gong)(gong)范圍廣等長處，篩管(guan)(guan)的(de)加(jia)(jia)工(gong)(gong)(gong)(gong)該當(dang)先選用(yong)(yong)激(ji)光(guang)加(jia)(jia)工(gong)(gong)(gong)(gong)梯形縫和寬縫的(de)加(jia)(jia)工(gong)(gong)(gong)(gong)難度(du)較大(da)，采用(yong)(yong)復合變位法(fa)和特殊的(de)工(gong)(gong)(gong)(gong)藝(yi)方案(an)可處理這些技術(shu)難題。激(ji)光(guang)切割篩管(guan)(guan)的(de)關鍵在于選用(yong)(yong)合理的(de)工(gong)(gong)(gong)(gong)藝(yi)參(can)數(shu)參(can)數(shu)選用(yong)(yong)不合理睬形成不同的(de)加(jia)(jia)工(gong)(gong)(gong)(gong)品質(zhi)缺(que)陷，甚(shen)至(zhi)使(shi)整(zheng)根篩管(guan)(guan)報廢該當(dang)不時優化加(jia)(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝(yi)參(can)數(shu)提升篩管(guan)(guan)加(jia)(jia)工(gong)(gong)(gong)(gong)品質(zhi)。
