Deepwater gas well testing in the South China Sea is characterized by high difficulty, investment and risk. In order to reduce effectively risk of operation Sea, potential factors deepwater were analyzed 42 categories identified. The fault tree analysis method was used establish model for a well, analyze inter restricted relationship between risks. Combining with hierarchical calculate weight values evaluation indicators use product it probability importance as corrected value occurrence basic event model, performed determine top-level event. results study help accidents operations can inform management sites.
