德克萨斯大学奥斯汀分校项目旨在为 MPD 运营提供下一代跳闸事件检测

将科里奥利流量计测得的流出量与钻机泵产生的流入量(直接比较或通过 Delta-flow 进行比较)进行比较,可以为钻井、起下钻和固井过程中的井涌和漏失提供有价值的早期事件检测工具。Delta-flow 随时间的变化可以得出体积测量值,也称为“虚拟起下钻罐”或“QV”。这模拟了小型井坑或起下钻罐的行为,比主动 PVT 更准确。然而,尽管 MPD 系统提供了这些宝贵的早期事件检测工具,并且它们应该是自动化和可靠的,但实际上它们直接依赖于手动调整的设置来校准测量值。在墨西哥城举行的 2025 年 IADC/SPE 控压钻井和欠平衡作业会议上,德克萨斯大学奥斯汀分校的研究生助理 Santiago Callerio 介绍了一个旨在改进这一流程的项目,从而减少误报和时间损失。

UT Austin project targets next-gen tripping event detection for MPD operations

Comparing the flow-out measured by the Coriolis flowmeters to the flow-in produced by the rig pumps, either directly or by Delta-flow, provides a valuable early event detection tool for kicks and losses while drilling, tripping and cementing the well. The integration of Delta-flow along time yields a volume measurement, also called “virtual trip tank” or “EQV.” This mimics the behavior of a small pit or trip tank, resulting in more accuracy than the active PVT. However, although MPD systems provide these valuable early event detection tools and they are supposed to be automated and reliable, in reality they are directly dependent on manually adjusted settings to calibrate measurements. At the 2025 IADC/SPE Managed Pressure Drilling & Underbalanced Operations Conference in Mexico City, Santiago Callerio, Graduate Research Assistant at UT Austin, talked about a project aiming to improve this process, thereby reducing false alarms and lost time.
