Automatic suction and discharge control system for oilfield mud cleaning

Abstract

Provide an automatic suction and discharge control system for oil field mud cleaning, including power supply, switch, controller, engine, vacuum pump, collection tank, exhaust butterfly valve, tank cover and suction port, the exhaust butterfly valve and tank cover are located in the collection Tank installation; the tank cover is hingedly connected to the bottom of the collection tank and the tank cover is automatically opened or closed by the disappearance or generation of vacuum force; the power supply is electrically connected to the input end of the controller through the switch, and is electrically connected to the engine and exhaust through the output end of the controller. Air butterfly valve; wherein the engine is connected to a vacuum pump to drive the vacuum pump to run with the engine at rated power or at idle speed; the controller includes a suction mode and a discharge mode that are controlled alternately and continuously by a time relay. The invention solves the technical problem that the pumping and discharging cannot work continuously, which leads to the slow construction process of oil field mud pumping and discharging; the structure is simple; easy to realize; convenient, practical, safe and efficient.

Description

technical field [0001] The invention belongs to the technical field of oilfield drilling equipment, and in particular relates to an automatic suction and discharge control system for oilfield mud cleaning. Background technique [0002] During oil field workover and drilling rig operations, it is necessary to rely on the mud pump to pour mud into the wellhead to complete the drilling and workover operations. After the operation is completed, the mud needs to be effectively recovered and reprocessed so that the mud can be recycled and reused, saving mud resources with special viscosity requirements and reducing mining costs. In the automatic suction and discharge process of mud under the prior art, a long stagnation operation time is reserved between the suction process and the discharge process: specifically: if you want to carry out the discharge process after the suction process is completed, you must wait for the lifting mechanism Only when one end of the collection tank ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem solved by the present invention is to provide an automatic suction and discharge control system for oil field mud cleaning, through the improvement of the control system for continuous and alternate operation of automatic suction and discharge, and the improvement of the tank cover opened or closed by vacuum force, Solve the technical problems that the mud cleaning collection and discharge control system in the existing technology cannot operate continuously and alternately, resulting in low efficiency, long cycle, labor-intensive and time-consuming process of oil field mud suction and discharge
