Oilfield Exploration Knowledge Base System Design

Oil field exploration enterprises have accumulated rich experience in oil field exploration in the past few decades,but how to combine these valuable experience with the actual science and technology into the standard standard in the process of enterprise production is an urgent problem for the oil enterprises to solve.Under this background,the construction of oilfield exploration knowledge base system arises at the historic moment.This paper studies and designs the knowledge base system of oilfield survey,and studies the key technologies in the knowledge base system of oilfield exploration.This paper first reviews the background and significance of the research.Secondly,the main research work involved in the design and implementation of the oilfield survey knowledge base management system includes:(1)for the construction of the oilfield exploration knowledge base management system to meet the fixed income situation the numerical value of the project cannot be estimated.Firstly,a one-element regression model based on the least squares algorithm is proposed to realize the estimation method of the project value.Secondly,the corresponding regression model is solved by using the sample data of the oil company's historical project income,and finally the model is adopted.Estimate the number of projects the company will need to meet a certain return value in 2018.(2)There is no keyword identification for the knowledge in the oilfield exploration knowledge base management system,which leads to the user missing the knowledge problem without keyword identification when searching through keywords.An improved keyword matching algorithm is proposed.The Text Rank algorithm initially extracts the keywords of each text,and then uses the TF-IDF algorithm to filter out the more important keywords from the keywords extracted in the first step as keywords of the knowledge,so as to facilitate the user.Search operations for related knowledge.(3)Design and implement the system management module,project management module,project location management module,knowledge management module,predictive management module,statistical analysis management module and accessory management module in the oilfield exploration knowledge base management system.The actual on-line operation of the system shows that the construction of the field survey knowledge base management system has achieved the desired effect of the user,which provides a unified platform for the management of knowledge for the enterprise and the rapid access of knowledge to the internal users of the enterprise.
