DB61/T 1177-2018 The technical requirements for effective thickness interpretation of low- and ultra-low permeability sandstone oil (gas) layers
Basic Information
Scope
This standard specifies the terms and definitions of the effective thickness of proven reserves in low-permeability and ultra-low-permeability sandstone oil (gas) fields (deposits), data collection, data review, interpretation standards for effective thickness, and technical requirements for oil and gas layer identification and comprehensive interpretation of effective thickness. This standard applies to the identification of oil and gas layers, interpretation of effective thickness, calculation of proven reserves, and preparation of reports for proven reserves in low-permeability and ultra-low-permeability sandstone oil (gas) fields (deposits) within the Ordos Basin in Shaanxi Province. Similar oil and gas fields in other basins can refer to and use this standard for reference.
