Study on Hydrate Control Measures in Deepwater Gas Wellbore under Intervention Operations

Abstract Hydrate control research is of great significance to the efficient development deepwater gas wells. A well intervention wellbore hydrate suppression experimental device was built simulate field operation and monitor generation in kettle real time. The physical simulation experiments were conducted for injection concentration, volume, rate glycol inhibitor different working conditions operation. results show that inhibition effect good when concentration solution 40%, plugging slow volume 20 mL, effective 4 mL/min. can effectively delay time required ensure above provide ideas in-wellbore operations field.
