Обоснование внедрения технологии термометрической косы в интеллектуальных скважинах

Abstract

Operation of a modern well is impossible without a constant monitoring system. Such systems include various control and measuring devices, pressure and temperature sensors, which makes the well operation predictable, trouble-free and efficient. Active introduction of digital technologies has greatly influenced many industries, including the oil and gas sector. The widespread use of computerization has facilitated oil and gas production. Streams of digital information about the field, its drilling, development of hydrocarbon raw materials, marketing of oil, gas and refined products, as well as interactive processes for monitoring and managing market conditions for oil and gas companies get to the headquarters and become available to the decision makers. The technology of creating smart wells has led to one of the most significant breakthroughs in intelligent innovative technologies of hydrocarbon production in recent years. There are discussed the temperature measurement technologies used in the smart wells and provided comparison of their characteristics, a description of the operation scheme, as well as the structure of each technology. The well-established fiber-optic system in operation is considered, as well as a new analog development - a thermometric chain. The scheme of a thermometric spit is illustrated and a detailed description of the relationship of its constituent elements is given. There are given the main advantages of the thermometric chain over the fiber-optic systems and the explanation for its choice during the operation of the well.
