螺旋鉆桿專(zhuān)業(yè)的制造技術(shù)分析

螺旋鉆桿是在尾部帶有螺紋的鋼管，用于連接鉆機的地面設備和位于鉆探井底端的鉆磨設備或井底設備。螺旋鉆桿的目的是將鉆探泥漿輸送到鉆頭，并與鉆頭一起升高，降低或旋轉井底鉆具。鉆桿必須能夠承受巨大的內部和外部壓力，扭曲，彎曲和振動(dòng)。在石油和天然氣的提取和精煉過(guò)程中，螺旋鉆桿可多次使用。

壓風(fēng)降溫鉆頭說(shuō)明書(shū)——瑞龍鉆具

當前，在煤礦瓦S抽放施工鉆孔中，因煤礦地質(zhì)條件和工藝要求，鉆孔過(guò)程中通過(guò)注水或者注風(fēng)以達到對鉆頭冷卻降溫目的，防止因高速旋轉摩擦造成的溫度過(guò)高而造成復合片磨損脫落。注水鉆進(jìn)實(shí)施中，由于水量大小變化及地層巖石松軟程度不同，常常會(huì )因為遇水巖石發(fā)育膨脹造成堵孔，而且注水鉆進(jìn)在進(jìn)行負角度及垂直鉆孔時(shí)往往因為反渣效果較差造成卡鉆，中途停鉆因巖屑遇水凝固而造成鉆桿抱死，因此注水鉆進(jìn)在很多情況下不適合復合片鉆頭鉆孔使用。普通風(fēng)壓鉆進(jìn)時(shí)風(fēng)壓通過(guò)鉆桿內孔傳遞至復合片鉆頭處，傳遞時(shí)由于鉆桿密封及輸送距離較長(cháng)導致風(fēng)量流失達不到的降溫效果，由于通風(fēng)孔徑較大，風(fēng)量分散不均勻，無(wú)法達到良好的排渣效果。我公司經(jīng)過(guò)長(cháng)期與煤礦一線(xiàn)使用單位合作調研，研發(fā)了一種壓風(fēng)排渣復合片鉆頭，其特征在于復合片下端設有的壓風(fēng)出口，其出風(fēng)口孔徑不大于2mm，壓風(fēng)出口與復合片夾角在110°~115°之間，通過(guò)高壓風(fēng)在2mm噴孔內形成急速射流風(fēng)，后按照角度布置直吹復合片鉆進(jìn)刃角部位，從而達到迅速降溫的目的。壓風(fēng)降溫排渣復合片鉆頭，其主要結構由冠狀結構主體、壓風(fēng)噴孔裝置和復合片等結構組成，冠狀結構主體頂部為多體分翼組合形狀，冠部刀翼位置布置有復合片，復合片下端設有壓風(fēng)出口，壓風(fēng)出口通過(guò)高壓風(fēng)對復合片進(jìn)行風(fēng)冷降溫防止因風(fēng)量不足及風(fēng)速不夠造成的燒鉆、磨損等現象，通過(guò)高壓風(fēng)冷可解決鉆頭在鉆進(jìn)斷層時(shí)所產(chǎn)生的卡鉆現象，并是水冷鉆進(jìn)的4—5倍。壓風(fēng)降溫排渣復合片鉆頭可解決在鉆進(jìn)過(guò)程中所造成的高溫燒片現象，并通過(guò)高風(fēng)壓鉆進(jìn)增加排渣速度，達到節能降耗的目的。
