摘　　要：元坝地区海相储层资源丰富,目的层垂深超深,具有高温、高压和含H2S等特点。应用水平井技术能高效地开发其产能,但存在测量仪器和定向工具选择难、轨迹控制难度大和钻井液性能调控难度大等技术难点。通过跟踪分析元坝地区首次施工的两口超深水平井元坝103H井和元坝121H井,优选了适应元坝超深水平井工况的定向仪器和工具,形成了系统可行的超深水平井轨迹控制技术和超深水平井钻井液技术,为元坝地区海相储层的高效开发奠定了基础。Yuanba marine reservoirs is very deep with the characters of high temperature,high pressure and H_2S.The horizontal well technique is applied to develop Yuanba marine reservoirs.The main technical difficulties are selection of survey instrument and orienting tool,trajectory control and drilling fluid property regulating.Through analyzing the field operation techniques of Yuanba 121H and 103H ultra-horizontal wells,the survey instrument and orienting tool suited for Yuanba area were selected,and the trajectory control technique and drilling fluid technique suited for Yuanba ultra-deep horizontal well were also formed.
