Overflow leakage monitoring and alarm system

Abstract

The invention discloses an overflow leakage monitoring and alarm system. The overflow leakage monitoring and alarm system comprises a pump impulse sensor, an outlet flowmeter, a vertical pipe pressuresensor, a drilling time sensor, a drilling pressure sensor, a drilling disc speed sensor, a PLC, an industrial personal computer and a display alarm module; and the pump impulse sensor, the outlet flowmeter, the vertical pipe pressure sensor, the drilling time sensor, the drilling pressure sensor and the drilling disc speed sensor are correspondingly connected with the PLC, the PLC is connected with the industrial personal computer, and the industrial personal computer is connected with the display alarm module. The provided overflow leakage monitoring and alarm system can accurately discoveroverflow and leakage, and provides technical guarantee for safe and rapid drilling well-completion operation.

Description

technical field [0001] The invention relates to the technical field of oil and gas drilling and completion production, and more specifically relates to an overflow leakage monitoring and alarm system. Background technique [0002] In the oil and gas drilling and completion production process, the timeliness and accuracy of overflow and leakage monitoring and alarming directly affect safe production, drilling and completion timeliness, environmental protection, personnel injury, and loss of facilities and equipment, which is the prerequisite for safe production. [0003] The current monitoring method for overflow and leakage is to monitor the overflow and leakage by installing liquid level sensors in the mud tanks to measure the volume of mud in each mud tank. Factors such as unstable liquid level, existence of air bubbles, internal volume of the pipeline from the wellhead to the mud tank, feeding, draining, backfilling and other factors may easily cause delay and inaccuracy ...
