鉆(zhan)桿在鉆(zhan)探過程中(zhong)是常(chang)(chang)用(yong)的易損工(gong)具，這要(yao)求經常(chang)(chang)使用(yong)鉆(zhan)機的用(yong)戶要(yao)多了解(jie)一些相關的知(zhi)識(shi)，我(wo)們都知(zhi)道(dao)，鉆(zhan)桿的作用(yong)是非常(chang)(chang)大的，鉆(zhan)桿于(yu)哪些作用(yong)和特點呢

地質鉆桿作用

鉆(zhan)(zhan)桿用(yong)(yong)于(yu)連接鉆(zhan)(zhan)機地(di)表(biao)設備和(he)位(wei)于(yu)鉆(zhan)(zhan)井底(di)(di)端鉆(zhan)(zhan)磨設備或底(di)(di)孔裝置(zhi)，是(shi)尾部帶有縲紋(wen)的(de)鋼管。鉆(zhan)(zhan)桿的(de)用(yong)(yong)途(tu)是(shi)將(jiang)鉆(zhan)(zhan)探泥漿運送(song)到(dao)鉆(zhan)(zhan)頭，并(bing)將(jiang)鉆(zhan)(zhan)頭提升、降低(di)或旋轉底(di)(di)孔裝置(zhi)。鉆(zhan)(zhan)桿必須能夠承(cheng)受巨大的(de)內(nei)外壓力、扭曲李、彎(wan)曲力和(he)振動(dong)。在開采和(he)提煉過程中(zhong)，鉆(zhan)(zhan)桿可重復使用(yong)(yong)。

原鋼(gang)管(guan)(guan)材(cai)和(he)光管(guan)(guan)在經過多次加(jia)工步(bu)驟后被(bei)制成鉆(zhan)桿。首先，通(tong)過鋼(gang)管(guan)(guan)加(jia)厚工序的(de)處(chu)理(li)， 光管(guan)(guan)外(wai)表面向內彎，鋼(gang)管(guan)(guan)管(guan)(guan)壁加(jia)厚。下一步(bu)，進(jin)行(xing)螺紋加(jia)工并鍍上(shang)能夠增加(jia)強度(du)的(de)銅(tong)。然后進(jin)行(xing)非破壞性質量控制，隨后進(jin)行(xing)鋼(gang)管(guan)(guan)管(guan)(guan)體接頭的(de)焊(han)(han)接。而后，管(guan)(guan)體會經歷焊(han)(han)接熱處(chu)理(li)和(he)焊(han)(han)接最(zui)終處(chu)理(li)，以消除焊(han)(han)接殘余壓力。在對(dui)成品鉆(zhan)桿進(jin)行(xing)渡漆和(he)包裝(zhuang)前要對(dui)鋼(gang)管(guan)(guan)成品進(jin)行(xing)其他的(de)一些(xie)檢測(ce)(ce)，包括硬度(du)測(ce)(ce)試，壓力測(ce)(ce)試和(he)非破壞性測(ce)(ce)試。鉆(zhan)桿的(de)長度(du)一般在九(jiu)米左右。
