Solid drill rig digital monitoring method

Abstract

The invention discloses a solid drill rig digital monitoring system. The system can be divided into six main units including a field equipment monitoring unit, a field environment monitoring unit, a mathematical model, a real-time operation unit, a client and a storage unit. The field equipment monitoring unit and the field environment monitoring unit are installed on the field and used for acquiring field equipment data and field environment information, the mathematical model is used for storing methods required for calculation, the real-time operation unit is used for logic calculation of the data and can directly output calculation results of a simulation model, carry out early-warning of limiting value exceeding, print reports and recommend operations, and the client is used for operation personnel and technical service personnel to check system monitoring states; the storage unit is used for archiving historical data, and the storage unit can be located in the local, or a remote server or the cloud end. Accurate calculation and quantitative display are achieved for problems which are judged by experience in the past, misjudgment caused by subjective experience of operators is avoided, non-planned halt is avoided, the operation efficiency is improved, the operation cost is reduced, and accessories are reasonably prepared.

Description

technical field [0001] The invention belongs to the technical field of oil drilling equipment control, and relates to a digital monitoring method for a physical drilling rig. Background technique [0002] The oil drilling rig is a continuous operation mechanical equipment. Once the drilling starts, it is not allowed to stop before the drilling is completed. And some wearing parts in this mechanical system must be replaced regularly, otherwise it will cause unexpected shutdown due to component failure, and in severe cases, it will cause huge economic losses. At present, there are two methods for estimating the service life of key consumable parts: calculating the running time and judging by experience. For example, the cylinder liner of the drilling pump generally uses the running time to determine the replacement cycle; the brake pads and bearings of the drawworks rely on the experience of the operator to judge whether they need to be replaced. Although these two methods h...
