Abstract

В заявке описано использование в пробоотборниках термически перестраиваемых оптических датчиков для анализа проб, полученных в скважине. Термически перестраиваемые оптические датчики испускают последовательность узкополосных излучений и регистрируют ослабление сигнала от них. Зарегистрированное ослабление обрабатывают и используют для определения параметров проб. Анализ может быть выполнен в удаленном месте (вне скважины), в скважине (в процессе бурения или на другом этапе) или как часть иного процесса, такого как распределение флюида, транспортировка и обработка.
