The seismic reflection wave amplitude variation with offset (AVO) technique can effectively extract the lithology and fluid parameters that are hidden in the seismic record, and thus can be applied to gas hydrate prospecting and assessments in the permafrost region. Based on the geological conditions of pore-filling gas hydrate reservoir in Qilian mountain permafrost, the forward simulation velocity...
This paper studies the technologies of information extraction and data mining. By using web crawlers to analyze and process the specified block of text, a system for document analysis is completed. For specific needs, this system is able to simulate the working process of the search engines. By intercepting the data flow, the automatic extraction and filtering of the document are achieved, so it effectively...
