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,优选适应元坝超深水平井工况的定向仪器和工具,确定超深水平井钻井技术方案。
Yuanba marine reservoirs is very rich and deep with the characteristics of high temperature, high pres-sure and H2S. The horizontal well technique is applied to develop Yuanba marine reservoirs. The main technicaldifficulties are selection of survey instrument and orientating tool, path control, control of mud fluid behavior.Through tracking the two Yuanba ultra - deep horizontal wells which are put in construction for the first time inYuanba region, we can optimize the survey instrument and orientating tool to get technique plan of drilling technolo-gy of ultra - deep horizontal wells.
