　　隨著石油天然氣需求的不斷增大,油氣資源的勘探開發(fā)深度也在不斷增加。為了提高單井產(chǎn)量、降低油氣開采成本,水平井、叢式井、大位移井等定向井的鉆井數(shù)量越來越多,對井眼軌跡的控制精度要求越來越高。在此大背景下,各種提高定向井施工精度和施工效率的工具不斷出現(xiàn)。其中應用最為廣泛的是井底液力馬達驅(qū)動的旋轉(zhuǎn)導向工具。這種導向工具的地面與井底的通訊方法為泥漿脈沖(MPT)。這種通訊方式或數(shù)據(jù)傳輸方式傳輸速度低、傳輸數(shù)據(jù)量小、傳輸精度易受井底振動的影響。為了提高數(shù)據(jù)傳輸速度、克服泥漿脈沖傳輸(MPT)的缺陷,隨后又出現(xiàn)了帶纜鉆桿(WDP)傳輸方式。為了確保WDP的傳輸質(zhì)量與強度,需在鉆柱上安裝鋰電池電源供電。由于受鋰電池耐溫能力和供電時間的限制,這種傳輸方法的適應井深受到限制。為了提高旋轉(zhuǎn)導向工具的數(shù)據(jù)傳輸速度與鉆井軌跡精度,消除高溫高壓對現(xiàn)有數(shù)據(jù)傳輸方式的影響,開發(fā)新一代旋轉(zhuǎn)導向工具迫在眉睫。本研究呈現(xiàn)了雙壁通纜鉆桿的發(fā)展歷程,提出了新一代電驅(qū)動旋轉(zhuǎn)導向工具的概念和設計。論文從文獻調(diào)研入手,收集分析了旋轉(zhuǎn)導向工具方面的論文150余篇。分別從電驅(qū)動井底工具、泥漿驅(qū)動的旋轉(zhuǎn)導向工具、帶纜鉆桿數(shù)據(jù)傳輸方法三方...
