Abstract

The invention relates to the field of solid control systems of petroleum drilling rigs, in particular to an automatic control method of a modular solid control system of a drilling rig. The modular solid control system of the drilling rig comprises a pipeline and a vibrating screen tank, an all-in-one machine tank, a centrifuge tank, a suction tank, a plurality of reserve tanks and a slurry mixingtank which are connected through the pipeline; and a central processor is installed in a comprehensive control room, and the central processor is electrically connected with PLC processors on the vibrating screen tank, the all-in-one machine tank, the centrifuge tank, the suction tank, the reserve tanks and the slurry mixing tank respectively. The automatic control method of the modular solid control system of the drilling rig comprises the following steps of 1) selecting the number of tanks, levels of the solid control system for purification and the placement style of the tanks; and 2) entering a modular solid control intelligent control system in the central processor to automatically control the solid control system. The defects of the prior art are overcome, the automatic control modular solid control system of the drilling rig and control method are provided, and the problem that an existing solid control system is inconvenient to operate and control is solved.

Description

technical field [0001] The invention relates to the field of oil drilling rig solid control systems, in particular to a modular drilling rig solid control system and an automatic control method thereof. Background technique [0002] Petroleum solids control system is mainly to control and separate the solids of petroleum drilling fluid, which can make the drilling fluid recycle, also called mud purification system. It is suitable for the drilling process of oil wells. The petroleum solid control system is composed of multiple modular combined tanks; the bottom of the mud tank adopts a new type of conical bottom structure, and the edge is not easy to settle sand; They can be separated and connected to meet the needs of drilling operations. The entire circulation system is equipped with several stages of purification system optional. You can choose the current 6-stage purification system that is commonly used, or you can choose the current relatively advanced 4-stage purific...
