Cable Conveying and Releasing Logging Meter in Complicated Horizontal Wells in Western Sichuan
-
摘要: 川西地区水平井在进行常规泵出式测井时,若钻杆不能下到位会造成漏测水平段油气层,针对这一问题,对常规泵出式测井工艺进行了改良,研制了特制引鞋、电缆旁通短节、熔断式马笼头和抓捞器等测井工具,形成了泵送电缆释放测井工艺。该测井工艺将钻杆下至预定位置后,从钻杆内用电缆将测井仪输送至遇阻位置,利用高压钻井液将测井仪推送至预定位置,然后供电分离电缆与测井仪,回收电缆后起钻测井,测井结束后,将测井仪打捞出,读取测井数据。泵送电缆释放测井工艺在川西地区复杂井眼轨迹水平井测井中应用了13井次,测井一次成功率100%,获取了全部水平段自然伽马、双侧向、补偿声波时差、补偿中子等测井曲线,且质量满足行业标准,合格率100%。现场应用表明,泵送电缆释放测井工艺能满足复杂井眼轨迹水平井测井需要。Abstract: Due to conventional pump-out logging methods in horizontal-well it was not possible to run drill pipe or logs to the expected position in Western Sichuan, resulting in the loss of oil and gas data measurement. To solve the problem, conventional logging technology was improved by specially designing a guide shoe, cable bypass pup joint, fusing cable head and catch tools, and a technology of pumping down cables for conveying and releasing logging meter was developed, i.e. the drill pipe was lowered to the bottom hole, conveying the logging tools to the sticking point, and then pushing it to the predetermined position by pumping drilling fluids, where the cables were separated with logging tools, and the logging operation was conducted after the cables were recovered, Finally, the drill pipes were pulled out of the hole, so that the logging data could be read after logging tools were taken out of the hole. In western Sichuan, the pumping cable technology for conveying and releasing logging meter has been applied 13 times in complicated-trajectory horizontal wells, with one-time logging success rate of 100%, resulting in successful logging curves for natural gamma ray, dual lateral logging, compensation interval transit time, compensated neutron logs being obtained, with all the curves meeting the SY/T 5132-2003 Industrial Standard. Field application showed that pumping cable technology for conveying and releasing logging meter was applicable to the horizontal wells with complicated well trajectory.
