Abstract: The automatic data acquisition system identifies, collects and processes production data automatically in different formats, structures and categories, which helps improvethe data acquisition efficiency of coalbed methane production.The system search table title and analyze table structure of Word file and Excel file, and use table recognition or keyword recognition to identify single cell, continuous multiple cells, key value pairs and data table.Results from coalbed methane wells of south Shizhuang block show that the system can extract and collect production data accurately and efficiently,providing an effective technical approach for the coalbed methane fields.
