Development & Research Of Optimized Monitoring System For Oilfield Water-injection Based On Fieldbus Technology

This thesis mainly describes energy-conservation optimization monitoring system of the oil-filed water flooding based on Fieldbus Technology. After analyzing the situation such as the technological process, technical indicator, equipments etc. of Water-injection Pumping Station, an overall scheme based on Filedbus technology of the whole monitoring system is proposed. Optimized control of pumps station is the prerequisite of realizing the whole water flooding system optimization. This thesis combines the characteristic of the water pump and the project's real requirements, targets the water flooding pump station that is composed of the reciprocating and centrifugal water pump, aimed at its optimization restraint terms, modeling method, resolution algorithm and control strategy, make the researches of the theory and simulation and get a satisfactory result. This thesis also introduces the newly developing Fieldbus control technology. Introduce and analysis the Siemens PROFIBUS digital data communication technology, and build the communication network of the while monitoring system by the communication technology, introduces the whole network build-up steps, introduces the convenience and performance improvement brought to realization of the project in use of the Fieldbus technology. Finally, the author briefly introduce the WinCC system used to design the configuration pictures of system upper computer and the ODBC technology used to access the WinCC database, analyze and design the whole monitoring system software, introduces the main module of the program and software's basic functions.
