针对进入油田开发晚期的无利润井或是低产井 ,作者与俄罗斯鞑靼斯坦石油股份公司的专家们一起对原有的技术方法进行了改进 ,并提出了一个以提高侧钻无利润井采收率为目标的综合工艺技术方案。应用先进的CardwellIri设备 ,分二步进行侧钻工程 :①工艺报废作业 ;②固定尾管 ,二次射开油层。同时试验成功了固定尾管的技术方法和工艺。文中还就井身分离器的结构和应用工艺进行了详细描述。
In response to entering the unprofitable or low-yielding wells in the late stage of oilfield development, the author, together with experts from Russia’s Tatarstan Petroleum AG, made improvements to the original technical methods and put forward a proposal to improve the recovery of sideways drilled non-profit wells Rate as the goal of comprehensive technology solutions. The application of advanced CardwellIri equipment, carried out in two steps sidetrack project: ① scrapped operations; ② fixed tail pipe, shot off the second oil. At the same time the successful trial of the fixed tail pipe technology and technology. The article also describes the structure and application process of well separator.
