摘要:渤中19-6凝析气田单井日产原油近400立方米
|
9月1日,渤海油田传来消息,渤中19-6凝析气田一口井喜获高产,单井日产气超过21万立方米、单井日产原油接近400立方米,油气产能远超配产。 On September 1st, the Bohai Oilfield announced that a well in the Bohai Middle 19-6 condensate gas field achieved high production. The daily output of gas from this well exceeded 210,000 cubic meters, and the daily output of crude oil was close to 400 cubic meters. The oil and gas production capacity far exceeded the planned output. 该井是超深开发井,6300米深的井需要连接起约700根钻杆。该井井下作业工况严苛,钻进扭矩相较常规作业增加约40%,接近钻具性能极限。 This well is a super-deep development well. A well that is 6,300 meters deep requires the connection of approximately 700 drill pipes. The downhole operation conditions of this well are extremely demanding. The drilling torque is approximately 40% higher than that in conventional operations, approaching the performance limit of the drilling tools. 此外,井下高温高压等复杂地层条件留给工程技术人员的有效作业窗口狭窄,井眼轨迹如果跟着地层“跑偏”,将很难被修正。在海底数千米地层下游弋的钻头时刻存在脱靶风险,需要技术人员及时判断地层走势并针对性控制调整,才能精准命中储层区块。 Furthermore, the complex underground conditions such as high temperature and high pressure leave engineers with a narrow effective working window. If the wellbore trajectory deviates from the geological formation, it will be extremely difficult to correct. The drill bit moving thousands of meters beneath the seabed always faces the risk of missing its target. Technical personnel need to promptly assess the geological trend and make targeted control adjustments to accurately hit the reservoir area. 为保障作业安全可控,同时确保该井投产产能,项目组坚持工程地质一体化协同攻坚。结合一期开发项目整体作业经验,项目组持续优化井漏防控、储层保护、提速提效等核心技术体系,进一步调整优化完井方案,实现完井作业阶段临时封井,最大程度保护储层,充分释放油气产能。 To ensure the safety and controllability of the operation, while also guaranteeing the production capacity of the well upon its commissioning, the project team has been conducting integrated geological engineering collaborative efforts. Based on the overall operation experience of the first-phase development project, the project team has continuously optimized the core technical systems for well leakage prevention, reservoir protection, speed-up and efficiency improvement, and further adjusted and optimized the completion plan, achieving temporary well sealing during the completion operation stage, thereby protecting the reservoir to the greatest extent and fully releasing the oil and gas production capacity. |
