Automatic drilling fluid-solid phase control system

Abstract

The invention discloses an automatic drilling fluid-solid phase control system. The automatic drilling fluid-solid phase control system comprises an elevated pipe, a solid control tank, a plurality ofsolid control devices, a plurality of valves, a control host, a control module, a displayer, a camera and an alarm, wherein the plurality of solid control devices comprise a vibrating screen, a degasser, a desander, a desilter, a centrifugal machine, a stirrer, a sand pump, a weighting pump and a shearing pump. The control host can be in control connection with all the devices in the system through the control module, the operating states of all the devices in the system can be monitored in real time, centralized control over all the devices and the valves can be achieved, online monitoring is conducted according to collected data, and abnormity alarming can be conducted. The automatic drilling fluid-solid phase control system has the advantages that the structure is simple, design is reasonable, using is convenient, safety and durability are achieved, the device cost is reduced, the labor intensity of manpower is relieved, and the drilling efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of petroleum drilling, in particular to an automatic drilling fluid solid phase control system. Background technique [0002] At present, the solid control system of domestic oil rigs is equipped with vibrating screens, sand pumps and other electrical equipment. The number is about 35 on average. The on-site maintenance workload is heavy, and all equipment failures cannot be predicted in advance. They are all shut down for maintenance or Use a backup device. Drilling fluid solid phase control is mostly manual operation. Mud workers need to travel to and from solid control areas according to different drilling fluid performance requirements, manually operate various equipment and valves to adjust mud flow and performance, and manually monitor drilling fluid parameters and various equipment operations. There are problems such as low safety factor, inconvenient use, and poor working environment. The drilling ...

[0002] At present, the solid control system of domestic oil rigs is equipped with vibrating screens, sand pumps and other electrical equipment. The number is about 35 on average. The on-site maintenance workload is heavy, and all equipment failures cannot be predicted in advance. They are all shut down for maintenance or use backup device

Drilling fluid solid phase control is mostly manual operation. Mud workers need to travel to and from solid control areas according to different drilling fluid performance requirements, manually operate various equipment and valves to adjust mud flow and performance, and manually monitor drilling fluid parameters and various equipment operations. There are problems such as low safety factor, inconvenient use, and poor working environment

The drilling site puts forward higher requirements for the informatization of drilling rigs, and it is urgent to carry out online monitoring and diagnosis technology research of the solids control system to solve the current on-site problems such as the low degree of informatization of the solids control system, the inability to obtain the operating status of the equipment in real time, and the high failure rate of the equipment
