Abstract: The method of exploration management and evaluation, which takes investment plans as its main form, can not thoroughly show the characteristics of oil and gas exploration. As a result, the notion of "operation quality of oil and gas exploration" and its evaluation contents are proposed in this thesis. It is suggested that oil and gas exploration be an integrated system, as well as the evaluation on operation quality be strengthened. All factors of exploration and production are analyzed, including the job schedule and its effect, the operation of seismic and exploratory work, the relationship between workload and reserves increment, the effect of current work on future exploration. This is beneficial to get a clear mind about current exploration and the key emphasis in work, accurately grasping the pace of work and the future development. It will play a key role in improving the analysis and management of exploration.

Key words: oil and gas exploration, operation quality, evaluation, decision making, management
