Because of gas well with higher content of carbon dioxide, the formed temperature of its natural gas hydras is higher, that makes natural gas hydras is easy to form in bore hole and surface gathering and transportation system, which is harmful to safety in production. Therefore, the reason of natural gas hydras blocking in the gathering and transportation system in gas well with higher content of carbon dioxide is analyzed, and the prevention and treatment measures of gas hydras is presented on the basis of analyzing adaptive of the present system, combining with the formed terminal condition of gas hydras. That are cleaning dirt and gas hydras in well bottom; applying water jacket heater and electric heat tracing to the equipments, and applying polyurethane rigid foam to keeping warm; injecting gas hydras inhibitor to line pipe; completing injection flow by outer transportation pipe; controlling measure temperature reasonably; formulating a reasonable cleaning-tube cycle. ©, 2015, Well Testing.
