摘　　要：针对海上油田深层定向电缆测井遇阻遇卡现象较多、录取资料困难的问题,提出了在非目的层井段完成造斜和降斜,并用套管封固,再采用直井段揭开目的层,形成“S”型井眼的设计方案,并通过优化钻井液性能,确保井壁稳定性,优选飞轮代替传统的测井工具扶正器等措施,最终实现资料录取目的,大大降低了电缆测井作业风险,目前已在南海东部推广应用。In view of the problems that the deep directional wireline logging in offshore oilfield encountered many obstacles and stuck,and it was difficult to obtain data,a scheme design was put forward to complete the deviation building and lowering in the well section of non-target formation and seal it with casing,and then open the target formation with vertical well section to form an“S”shaped well hole,and ensure the stability of the well wall by optimizing the drilling fluid properties.The optimized flywheel,which replaces the centralizer of the traditional logging tool,finally realizes the purpose of geology data acquisition and greatly reduces the risk of wireline logging.At present,it has been popularized and applied in the eastern South China Sea.
