石油钻探过程中，井控工作关乎人员、设备、生产安全，及时、精确发现溢流是井控安全预防的关键。塔河油田结合目前常规的监测方式，研发出高架槽上能够减缓钻井液波动、提升溢流监测的灵敏性“双挡板”装置和钻井液罐上的减缓液面波动装置，进行了现场试验；在大量数据统计分析的基础上，建立了溢流预警模型，开发出智能监测溢流预警系统，并应用于现场钻探中；探索了电磁流量计在钻井现场监测出口流量的应用。试验结果表明，上述方法与目前综合录井溢流监测方法相比较，可有效提高溢流预报的及时性和准确性，应用效果良好。

Well control is linked with staff, equipment and production safety in oil boring, so monitoring overflow quickly and accurately is a critical element of well controlling accident prevention. We have researched and tested some devices in field which named "double baffles" to slow down liquid level fluctuation to promote sensitivity on elevated tank, and to slow down liquid level fluctuation in mud tank. An overflow monitoring model and an intelligent early-warning system were established and applied to field work. Electromagnetic flowmeter was also applied to monitor the mud rate of flow. Compared to current methods, the new method can monitor overflow more quickly and accurately, and shows a good performance.
