新疆第一口水平井大斜度套管成功固井所采取的技术措施和一些新技术的应用。其中刚性旋流扶正器、强制式回压凡尔、低自由水水泥浆以及采用计算机进行摩阻计算分析、套管扶正器合理安放位置计算、利用清水和水泥浆密度差对套管的漂浮作用进一步使大斜度井段套管居中等技术均在该井成功应用。固井之后的声幅测井评价以及后期钻进实践表明该井固井是非常成功的。
Technical Measures for Successful Cementing of Large Inclined Casing in the First Horizontal Well in Xinjiang and Application of Some New Technologies. Among them, the rigid cyclone centralizer, forced back pressure Verstel, low free water cement slurry and computer calculation of friction resistance, casing centralizer reasonable placement, the use of water and slurry density difference on the casing floating The technology of further centering the casing of the high-gradient section is successfully applied in this well. Post-well sonic logging evaluation and post-drilling practices show that well cementing is very successful.
