Domestic Application Status of Downhole Corrosion Inspection and Monitoring Technique in Oil and Gas Wells

Abstract

In order to find corrosion and other defects of downhole tubing as early as possible in oil and gas production，and to ensure safe and efficient production of oil and gas，the article gave an overview of existing downhole corrosion inspection techniques and monitoring techniques for oil and gas wells both domestically and internationally.The application of the above techniques in domestic oil and gas fields were analyzed，and the prospects for the development of related techniques were putted forward.Furthermore，it was considered that improving the reliability and adaptability of the technology and equipment and achieving online monitoring and real-time monitoring were very important directions of researches.
