Embodiment Construction

[0037] In conjunction with the accompanying drawings, the present invention will be described in detail below.

[0038] refer to Figure 1 ~ Figure 4 , a hand-held condition monitoring and fault diagnosis system for oilfield injection-production equipment. During the operation of injection-production equipment, many working parameters such as pressure, flow, temperature, vibration, etc. can be used as monitoring signals to achieve the purpose of monitoring and maintenance . Among them, the vibration signal contains a wealth of operating status information, which is easy to pick up. The relevant signal processing theory is relatively mature, and it can be monitored without disassembly and assembly. Therefore, the present invention takes vibration measurement as the main implementation means of equipment monitoring.

[0039] In view of the above problems, the hand-held state monitoring and fault diagnosis system for oil field injection and production equipment provided by the ...

Abstract

The invention provides a handheld type condition monitoring and fault diagnosing system orienting to oil field injection-production equipment. The system comprises an embedded handheld end and an industrial-grade PC (Personal Computer) end, wherein the embedded handheld end is of a dual embedded processor structure of an upper computer and a lower computer and is composed of a lower computer real-time data acquisition system and an upper computer data processing analysis system, the lower computer real-time data acquisition system is a data acquisition card based on a mixed signal processing micro control unit, and the upper computer data processing analysis system is a condition monitoring card based on an advanced reduced instruction set computing machine; and the industrial-grade PC end is a depth data analysis system which is positioned in a control room of an oil field oil production plant, and is used for finishing off-line analysis tasks including related analysis, comparative analysis, trend prediction of equipment performance and generation and actuation of expert knowledge. The handheld type condition monitoring and fault diagnosing system orienting to the oil field injection-production equipment provided by the invention has the advantages of good flexibility, low requirement for working environment, wide application range, simple structure, simplicity and convenience in operation and lower cost.

Description

technical field [0001] The invention relates to the field of process monitoring and control of oilfield injection-production equipment, in particular to a hand-held state monitoring and fault diagnosis system for oilfield injection-production equipment. Background technique [0002] Oilfield injection-production equipment (such as pumping units, polymer injection pumps, water injection pumps, etc.) is the most widely used key equipment in oilfields. It has the characteristics of various types, scattered equipment locations, high requirements for continuous work, and harsh working environments. For many years, the maintenance and monitoring of injection-production equipment has generally adopted a regular inspection system, which cannot achieve real-time monitoring of operating status, and the predictive maintenance ability of equipment is poor. With the development of computer technology, some oilfields have implemented an online fault diagnosis system based on PC mode, whic...
