  • 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.
