System and method for monitoring health state of fracturing pump

Abstract

The invention discloses a system for monitoring the health state of a fracturing pump. The system comprises a position sensor, strain gauges, a computing device and a display device; and the positionsensor is used for detecting the real-time position of each plunger, and outputting a sensing signal representing the real-time position of each plunger, and the strain gauges are used for detecting the strain of all cylinders at a fluid end, and outputting sensing signals representing the strain of all the cylinders at the fluid end. According to the provided system for monitoring the health state of the fracturing pump, the operation state of the fracturing pump is monitored in real time, and the pump is examined and repaired according to the operation state of the fracturing pump, so that the maintenance frequency is reduced, the use efficiency of pump valve body accessories is improved, and the maintenance cost is reduced. The invention provides a method for monitoring the health stateof the fracturing pump. According to the method, by monitoring the trend of pressure change in the cylinders at the fluid end of the fracturing pump and monitoring the positions of the plungers for cooperation, the operation state of the fracturing pump can be judged by comparing the action delay of suction valves and discharge valves, then the health state of the fracturing pump can be identified, and then a basis is provided for the state examination and repair of the fracturing pump.

Description

technical field [0001] The invention relates to the technical field of petroleum fracturing operations, in particular to a system and method for monitoring the health state of a fracturing pump. Background technique [0002] 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 frequently. Frequent replacement of components adds additional cost to the replacement parts and additional time for the operation to install the replacement parts.
