| 摘 要： | 针对定北8井尾管固井的难点,采取防窜性能好的水泥浆体系、优化流体结构、带封隔器的悬挂器、合理的施工压力控制等综合的防窜漏工艺.由于在施工过程中发生了井漏和其它复杂情况,减小了压稳领浆段长度、增大了地层压力和液柱压力的压差,为气窜创造了通道导致气窜的发生,同时由于井漏的影响,导致水泥浆的顶替效率低从而影响水泥浆的胶结强度和固井质量.为以后深井尾管固井提供借鉴和指导意义.

| Abstract: | Aiming at the difficulties of the Liner Cementing for DINGBEI No.8 well,the authors of this paper take all the anti-leakage technologies during the liner cementing as follows: taking the good anti-channeling cement slurry system,and optimizing the fluid structure,using the hanger machine which with the hoisting of the packer,and taking a reasonable construction of the integrated stress control,etc.Because of the well leakage and other complications happened during the construction process,it reduces the ste... |
