Hunt Oil 着手减轻可能的地表井眼危害，例如浅层天然气、对抽吸敏感的地层、致密井眼、循环损失，并为位于罗马尼亚 Buzau 的 Macoveiu 3900 井的地表部分节省了时间。选择随钻套管作为应对这些挑战的解决方案。

在作业规划期间，由于钻机地面设备的限制，对可实现的最大工作流量设置了上限。该流量上限低于最佳操作性能所需的流量上限，因此这种情况需要对钻头性能、井眼水力学和孔清洁进行额外分析。针对预期条件对现有 20 英寸套管乘 24 英寸钻头设计进行了分析、优化和验证。

CwD 创下了旋转深度以下 798 m 的破纪录纪录，同时还带来了一系列其他优势。

通过实施 Odfjell Technology 的 CwD 服务，Hunt Oil 减少了所需的运行次数，由于消除了传统的井底组件处理和起下钻时间，从而节省了时间和成本。Hunt Oil 通过使用套管送入工具 (CRTi)、扭矩转动计算机、手动搬运工具、高扭矩液压动力钳和动力组，能够在这个 24 英寸断面实现钻井目标。

Odfjell 油井服务执行副总裁 Elisabeth Haram 表示：“该项目创造了欧洲创纪录的 CwD 性能，进一步证明 Odfjell 技术是提供行业领先油井服务（从规划、材料到执行）的首选。”技术。“作为该地区成熟的 CwD 提供商，Odfjell Technology 的油井服务套件在复杂多样的项目上为我们的客户节省了大量时间和成本。”

“与规划和工程相关的挑战转化为机遇，从而实现了这一成就并设定了新的里程碑。主要挑战是浅层气体、拭子和孔稳定性。由于出色的团队协作和持续努力，我们所有的目标都得以实现。随钻套管安全执行，没有发生可记录的事件或事故。我们非常感谢大家的努力和支持才能取得如此出色的成绩。该项目体现了有效沟通和团队合作的力量。”罗马尼亚亨特石油公司运营总监 Ciprian Rotareanu 说道。

Hunt Oil set out to mitigate possible surface hole hazards like shallow gas, formations sensitive to swabbing, tight hole, loss of circulation and have the benefit of time saving for the surface section of its Macoveiu 3900 well, located at Buzau, Romania. Casing while drilling was selected as the solution to these challenges.

During job planning, a cap was set on the maximum achievable working flowrate, due to rig surface equipment limitations. This flowrate ceiling was lower than what was required for optimal operational performance, so this scenario required additional analysis of the drill bit performance, the wellbore hydraulics and hole cleaning. The existing 20 in. casing by 24 in. bit design was analysed, optimised, and validated for the expected conditions.

A CwD record-breaking depth of 798 m below rotary was recorded, alongside a range of other benefits.

By implementing Odfjell Technology’s CwD services, Hunt Oil reduced the number of runs required, with a saving on time and cost, thanks to the elimination of conventional bottom hole assembly handling and tripping times. Hunt Oil was able to achieve its drilling objectives on this 24 in. section by using the casing running tool (CRTi), torque turn computers, manual handling tools, hydraulic power tongs with high torque capacity and power packs.

“Enabling a European record CwD performance for this project is further proof that Odfjell Technology is a prime choice for the delivery of industry-leading well services – from planning and materials to execution,” said Elisabeth Haram, EVP Well Services at Odfjell Technology. “As an established CwD provider in this region, Odfjell Technology’s suite of well services has a track record of saving our customers substantial hours and costs on complex and varied projects.”

“Challenges associated with planning and engineering turned to opportunities that led to this achievement and setting new milestones. The main challenges were shallow gas, swab, and hole stability. All of our objectives were achieved due to excellent team collaboration and continuous effort. Casing while drilling was executed safely with no recordable incidents or accidents. We much appreciate everyone’s effort and support for such an outstanding achievement. This project exemplifies the power of effective communication and teamwork,” said Ciprian Rotareanu, Operations Superintendent at Hunt Oil Company of Romania.
