Research On The Information Management System Of Downhole Operational Based On Workflow

Workflow technology is a rapidly evolving technology, its main feature is the automation of business processes, the handling of these processes are in computer applications and tools to help carry out its main features, namely, by the computer system to help people complete daily processing. Application of workflow technology, all kinds of processes are placed in the workflow platform, by operating database, provide report, statistics, retrieval, analysis and other functions. Through the work flow will bring different information to different information platform, collected the request and information to the system from a different platform ,so the staff of various departments, external visitors can realize efficient communication and collaboration.Along with the development of new technology in oilfield, With the development of new oil field technology development, the application of the downhole information will be further in-depth, professionals need access to large amounts of historical data to establish the program, and this work will spend a lot of time. From design to construction units under the scheme of construction, to completion of inspection, clearing and construction cost summary prepared, all the links in the basic independent, can not be integrated. With the significant increase in the number of construction jobs, construction results increasing year by year, resulting in accumulation of large amount of historical information, is not used effectively. Therefore, how the whole process of downhole information to track the implementation of a computer, has become a serious problem.This article describes the issues of the downhole work of research information management system. WebServices based workflow technology and the characteristics of the three-tier architecture, this paper focuses on the workflow reference model, workflow, Construction, AJAX and WebServices technology to establish a series of three-tier issues, and ultimately designed the application——the information management system of downhole operation.
