                                                                                                            旋挖鉆機前沿技術解讀

                                                                                                            發布時間:2019-07-29 瀏覽次數:1 次

                                                                                                            國內旋挖鉆機前沿技術概況:
                                                                                                            一、聲波旋挖鉆機的研制。聲波振動是一種比液壓振動頻率更高的的振動方式,旋挖鉆機運轉時只有輕微聲音,特別適應在大城市內施工。該旋挖鉆機工藝采用干式,無需水、空氣、其它添加劑,在各種由淤泥、粘土、砂、礫石、大鵝卵石組成的最難鉆進地層中施工都非常順利且效率非常高。
                                                                                                            二、多工藝旋挖鉆機的研制。旋挖鉆機采用模塊化設計,在基本機型基礎上可以通過選配不同的執行模塊實現多種鉆探工藝的快速切換。如多功能旋挖鉆機是一款適應于地質小口徑勘探用途的中淺孔多功能旋挖鉆機,既可以適用空氣反循環快速取樣鉆探工藝又可以適用于金剛石繩索取心鉆探工藝。如無錫的高壓旋噴旋挖鉆機可通過不同的模塊組合,可以適應定噴、擺噴、旋噴等施工工藝來滿足單重、雙重、三重等旋噴施工的要求。
                                                                                                            三、全自動頂驅旋挖鉆機的研制。旋挖鉆機是適用于深孔鉆探、超深孔取心鉆探的新一代交流變頻電動頂驅式巖心旋挖鉆機。通過PLC、觸摸屏、儀表系統,實現智能化司鉆控制,具備回轉、循環、接單根/立根、上卸扣、掃孔等綜合能,能實現恒壓+限速自動送鉆,控制精度高。
                                                                                                            六、交流變頻電傳動在立軸巖心旋挖鉆機上的應用。由張探和核工業二七0所研制的XY-8DB采用國際領先的交流變頻電驅動技術,實現了無極變速、數字化、遠程可視、集中操控,提高了操控精確度和安全性,降低勞動強度、節能降耗性能顯著。
                                                                                                            國內近幾年新的旋挖鉆機技術都是在國外研究的基礎上開發的,有的為了保證性能甚至采用國外的部件組成。
                                                                                                            國外前沿技術簡要概況
                                                                                                            一、旋挖鉆機全自動化。整個旋挖鉆機可實現全自動化,所有工作均由機器手或機器人來完成,并可實現遠程遙控。
                                                                                                            二、連續管旋挖鉆機。連續管技術在石油、天然氣勘探領域是一項全新的技術,國外已廣泛應用于鉆井、測井、修井等各領域,連續管旋挖鉆機被稱為“萬能作業機”。加拿大在此技術應用中走在前列。
                                                                                                            三、無旋挖式鉆井。其核心技術是利用高電壓脈沖在“鉆頭”前方的巖石中形成高能等離子體,等離子體在不到一微秒的時間內在巖石中極迅速地膨脹,導致局部巖石破裂或破碎。該型旋挖鉆機的“鉆頭”與電纜連接,用鋼繩吊入,改變了傳統機械破巖的方式,在硬質地層中效率非常高,孔筒光滑,孔的直徑小?,F在挪威已生產樣機,一旦試驗成功,必定成為勘探鉆孔技術上的一場革命,大幅度降低勘探鉆井費用和勘探風險。
                                                                                                            四、激光旋挖鉆機。激光能快速穿透各種巖石,在穿透的過程中擊碎、熔化、蒸化巖石。激光鉆井是常規鉆井的10倍以上,無需常規鉆頭和鉆具,無需下套管和固井,可節省大量的時間和成本;激光鉆井是一種清潔鉆井,不造成環境污染;同時激光方向可控,井的軌跡不受限制。美國在這方面走在最前列,試驗成功,同樣會給鉆井和完井帶來一場深刻革命。
