style="text-indent:25px"> 石油鉆桿接頭是在石油勘探開采鉆井時(shí)，用于連接上、下鉆桿的重要部件，由于其長期工作在含砂多，且有一定腐蝕性介質(zhì)的井下，所以要求其具有優(yōu)良的耐磨、耐蝕性能。為了改善其耐磨、耐蝕性能，提高其使用壽命，目前國內(nèi)許多企業(yè)采用粉末等離子噴焊的方法在其接頭部位噴焊一層耐磨帶。實(shí)驗(yàn)結(jié)果表明，噴焊層主要由：γ-Fe、Cr23C6、(Cr,Fe)7C3以及NiB、萊氏體等化合物相組成。焊層冶金結(jié)合較好，**致密，稀釋率低，無裂紋、夾雜等缺點(diǎn)。同時(shí)擁有較高的硬度（55～68HRC）和耐磨性，具有較大的應(yīng)用價(jià)值。2、鉆桿是石油天然氣行業(yè)進(jìn)行油氣資源勘探，開發(fā)過程中不可或缺的工具，是組成鉆柱的主要部件。在石油勘探開采鉆井時(shí)，鉆桿接頭用于連接上、下鉆桿，是石油鉆桿的薄弱環(huán)節(jié)，80%以上的鉆桿***出現(xiàn)在這個(gè)部位。因此提高鉆桿接頭的質(zhì)量，是降低***的關(guān)鍵。3、據(jù)了解，目前國內(nèi)大部分油田的鉆井深度都達(dá)到了幾百米，有的甚至更深，達(dá)到幾千米，而且?guī)r層復(fù)雜堅(jiān)硬，鉆桿在工作過程中，其外壁尤其是接頭部位要與井壁或套管接觸，所以承受著劇烈的磨損。由于鉆桿接頭周圍接觸面存在很多硬質(zhì)點(diǎn)，所以磨損主要以磨粒磨損為主，特別是下部目的層段使用屏蔽暫堵鉆井液時(shí)。上海鉆桿堆焊用在哪里比較好呢？</p><div

1、等離子弧區(qū)溫度高，所以能熔的材料特別***，可以對(duì)各種金屬進(jìn)行堆焊，還能選配各種不同性能的粉末進(jìn)行配置使用；而且等離子堆焊穩(wěn)定性好，粉末能均勻地噴射進(jìn)入弧柱以熔化材料，所以，堆焊層有很好的機(jī)械性能，和很高的粉末材料密度。2、離子堆焊沉積效率比較高，它可以自動(dòng)化操作，能很好的調(diào)節(jié)；為了保證合金材料性能，它有小于5%稀釋率，使用保護(hù)氣，不易氧化堆焊材料，在工作時(shí)一般采用氬氣和氦氣操作。3、離子堆焊有光滑平整的的堆焊層，而且可以精確控制尺寸范圍。堆焊件不容易變形，因?yàn)槎押笗r(shí)的粉末在弧柱中熔化并起到隔離作用，冷卻工件還可以使用氣體。4、等離子堆焊的技術(shù)優(yōu)勢(shì)更加明顯，母材和堆焊層實(shí)現(xiàn)了冶金結(jié)合，而且堆焊層不容易脫落，在堆焊的時(shí)候可以根據(jù)性能選擇堆焊合金材料，終達(dá)到耐磨和抗腐蝕，耐高溫和抗氧化等目的。鉆桿堆焊設(shè)備有發(fā)展前途嗎？重慶等離子粉末堆焊鉆桿堆焊堆焊房車</p><p
