Slurry transferring device for drilling fluid

Abstract

The invention belongs to the technical field of petroleum drilling fluid solid controlling processing devices and particularly relates to a slurry transferring device for drilling fluid. The device comprises a slurry transferring tank (1). A drilling fluid inlet (10) is formed in the top of the slurry transferring tank (1). The device is characterized in that a first sand pump (2) and a second sand pump (3) are connected with the bottom of the slurry transferring tank (1). An outlet of the first sand pump (2) is connected with a first automatic control valve (6), the first automatic control valve (6) is connected with a programmable logic controller (PLC) control system (5) through a first executor (8), an outlet of the second sand pump (3) is connected with a second automatic control valve (7), and the second automatic control valve (7) is connected with the PLC control system (5) through a second executor (9). By means of the slurry transferring device, when a drill machine main body is transferred, the number of modules of the drilling fluid solid controlling system translated as a whole is reduced, drilling fluid transferring and loss are avoided, and efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of oil drilling fluid solid control treatment equipment, and in particular relates to a drilling fluid slurry transfer device. Background technique [0002] In oil field drilling rig operation, it is necessary to use drilling fluid to cool the drill bit and remove cuttings, so that the drilling rig can work normally. In the drilling rig system, the drilling fluid required for the drilling rig operation is provided by using the solids control system. The current solids control system The main structure includes several mud storage tanks and solid control devices corresponding to each mud storage tank. The effective volume of the mud storage tank should be sufficient to accommodate the maximum circulation of drilling fluid during drilling, and have sufficient storage capacity to ensure The drilling rig is equipped with sufficient drilling fluid. [0003] Cluster wells refer to the drilling of several wells on...
