摘　　要：基于2010年美国证券交易委员会颁布了新的SEC储量准则,对证实未开发储量(PUD),以“合理确定性”标准代替了原有的“确定性”标准,以东方1-1气田为例,从合理井控范围、地球物理资料合理利用、WGC降压提高采收率技术等方面,对新增PUD储量进行合理确定性论证,得到了一致认可并顺利披露。对今后南海西部油气田上市储量评估工作具有指导意义。In 2010,the U.S.Securities and Exchange Commission issued a new SEC reserve standard,in which the“reasonable certainty”standard replaced the original“certainty”standard for proven undeveloped reserves,requiring a high degree of confidence in the estimated PUD reserves.Taking Dongfang 1-1 gas field as an example,this paper demonstrates the reasonable certainty of the new PUD reserves from the aspects of reasonable well control range,reasonable utilization of geophysical data,compressor depressurization and improving gas recovery,which has been unanimously recognized and smoothly disclosed.It is of guiding significance to the evaluation of the listed reserves of the western oil and gas fields in the South China Sea in the future.
