Abstract: Focusing on the issue of maintaining stable production in an oil and gas field in Iraq during the overhaul period of its natural gas processing units and conducts research and discussions. It analyzes the key factors that make it difficult to maintain stable production in the oil and gas field during the overhaul period and puts forward effective solutions. It analyzes the feasibility of the GSU unit's online operation during the overhaul period， upgrades and modifies the technological process， and systematically elaborates on the preconditions and safety precautions for the GSU-2 unit's online operation. Through process technology innovation and practice， the problems restricting production and maintaining stable production during the overhaul period have been effectively solved， thus ensuring the production tasks of the oil and gas field.
