Abstract: Hutubi gas field is the biggest field development by Xinjiang Oilfield Company. This paper analyzed the reservoir parameters, well-controlled reserves and reasonable production scale from the gas field, based on three-year various data from transient well test interpretation, providing sound basis for further determination of development policy of it. Also, it is pointed out that such a method is of certain values for reference in fully playing a role of the modern transient well test interpretation information, promoting the level of analyzing a gas field's performance as well as ensuring appropriate development of a gas field.
