快测平台SDZ5000在水平井中的应用

在大斜度和水平井环境中,由于复杂井眼结构,超深、超长裸眼井测井受到遇阻、遇卡的影响,测井时间长,仪器故障多。针对这些情况推广了快测平台仪测井工艺,应用快速测井平台测井方法和钻输测井施工优化设计,从多方面对快测平台测井工艺进行完善,使新技术在完成水平井、大位移定向井等复杂结构井测井中发挥作用。文中根据不同类型不同井身结构复杂井况情况,应用合理的钻输测井工艺,采用设计的施工方法,对下井仪器进行组合优化和加装辅助工具,保证测井安全又提高测井效率,解决了大斜度、超深井遇阻遇卡等复杂结构特殊井的测井任务。

Application of SDZ 5000 Express Well Logging Platform to Horizontal Drainhole

When logging the high angle deviated holes and horizontal wells because of the complex borehole surroundings,the logging of the superdeep wells and ultralongspaced wells will meet blockings and lockings.The result is that the logging time prolongs and instrumentation failure probability increases.According to the situation we generalized the logging technology of express platform.We used the methods of express platform and the optimized design of toolpusher logging to optimize the technology of express platform in many aspects,and that will play roles in logging complex boreholes such as horizontal wells,mega reach wells and so on.In this paper,according to different types and complex boreholes,we use rational technology of toolpusher logging and designed construction method to optimal combination tools and install accessory tools,so that we can assure the safety and efficiency of logging.The frequent blockings and lockings in complex borehole loggings are resolved.
