A fracturing pump online monitoring and fault diagnosis system

Abstract

The invention discloses an on-line monitoring and fault diagnosis system for fracturing pumps, which includes a signal acquisition module, a signal processing module and a data module; Including fault prediction and concurrency control module, threshold and window function setting module, vibration signal feature extraction and identification module respectively cross-linked with data, general signal processing module, rule-based prediction algorithm module, data sharing buffer module; To provide benchmark data and technical support data; the data is analyzed and processed by the signal processing module to obtain the working status of the main components of the pump. Therefore, the fracturing pump online monitoring and fault diagnosis system of the present invention realizes the integration of state monitoring-diagnosis-forecasting-treatment and management of fracturing pumps, reduces the operation and maintenance cost of fracturing pumps, and the present invention also discloses a The on-line monitoring and diagnosis method of the fracturing pump is based on the above system.

Description

technical field [0001] The invention relates to the field of equipment operation and maintenance, in particular to an online monitoring and fault diagnosis system for a fracturing pump. Background technique [0002] The fracturing pump is an important measure equipment for oil field water injection, fracturing, acidizing, etc. to improve the production and recovery of oil layers, and is widely used in various oil and gas fields. In the hydraulic fracturing operation, the pressure of the fracturing fluid is used to open the formation and form several cracks, so as to achieve the purpose of increasing production and injection. The fracturing pump is the core equipment to achieve this purpose. For the working conditions of fracturing construction, the fracturing pump is required to have the characteristics of high pressure, large displacement, strong corrosion resistance and wear resistance, which makes the parts of the fracturing pump easy to wear and need to be replaced frequ...

Problems solved by technology

The working state monitoring of valves has always been a problem in the industry. The industry usually uses the pressure difference between the inlet and outlet for monitoring. However, due to the very high pressure, the cost of a large-range and high-precision pressure sensor is very high, and this method cannot locate the working status of each valve. In addition, the internal structure of the fracturing pump is complex. If a component fails, it is difficult to locate it on site. Generally, it needs to be returned to the factory for repair, resulting in a decrease in the use efficiency of the equipment and greatly increasing the operating cost.
