摘　　要：以济阳坳陷勘探实践为例,针对成熟探区滞留的大量"出油点",摸清其现状,并估算"出油点"所在圈闭资源量来明确其资源规模;剖析制约每个"出油点"未上报储量的原因,即"出油点"产能未达储量起算标准、成藏主控因素复杂、地面条件限制。针对不同原因提出相应的升级对策,即配套工艺措施、加强地质研究、明确成藏主控因素及协商地面条件等,使"出油点"资源量升级,为近期三级储量上报做出贡献,节省大量勘探投入资金。Taking the Jiyang depression as on example,resource scale is defined by means of identification of present status of the 'Oil Seepage Points' significantly retained in mature exploration area and estimation of resources in traps with 'Oil Seepage Points' located;the constraints to unreported reserve in each 'Oil Seepage Point' is analyzed,including productivity of the 'Oil Seepage Point' below reserve eulofF for reporting,complicated controlling factors over reservoir forming and constraints in surface condition.Appropriate upgrading measures are proposed correspondingly for various constraints,including technical measures package,enhanced geologic study,identification of controlling factors over reservoir forming,negotiation on surface conditions and so on,allowing resource upgrading of the 'Oil Seepage Points',making conlribution to 3P reserves report and saving significantly investment in exploration.
