海上油气资源储量和潜在资源量分类

CLASSIFICATION OF RESERVES AND CONTINGENT RESOURCES OF OFFSHORE OIL AND GAS RESOURCES

根据海上油气资源勘探开发特点,在SPE油气资源分类理念下建立了具有中国海洋石油特色的《海上油气资源储量和潜在资源量分类》体系。分类体系将已发现油气资源划分为储量和潜在资源量2个类别,作为油气资源的分类基础。采用2个维度体现分类的主控要素,垂向上为油气田商业性状态和勘探开发阶段,横向上为油气资源的动用情况和开发状态。油气田划分为含油气构造、正在评价含油气构造、认定商业性油气田、在建设油气田和在生产油气田5种状态。油气资源的动用情况划分为已动用和未动用2种情况:已动用包括在生产中动用、方案中动用和计划中动用;未动用分为方案未动用和计划未动用。储量划分为已开发和未开发2种状态,潜在资源量划分为待开发和暂不开发2种状态,难动用储量划分为原油难动用储量和天然气难动用储量。

According to the needs in exploration and development of offshore oil and gas resources,a standard named"reserves and contingent resources classification of offshore oil and gas resources"is established under the concept of SPE with the characteristics of China’s offshore oil industry.As the basis of oil and gas resource classification,discovered oil and gas resources are firstly divided into reserves and contingent resources.Main factors are adopted as the two dimensions for classification.The vertical direction is commercial state and stage for exploration and development of the oil and gas field,while the horizontal direction is the utilization and development status of oil and gas resources.Oil and gas fields are then categorized into oil/gas-bearing structure,evaluating oil/gas-bearing structure,identified commercial oil and gas fields and oil and gas fields on construction or production;Utilization status of oil and gas resources is classified into the used and unused.The used oil and gas include those in production,in plan and in scheme.The unused oil and gas involve in plan unused and in scheme unused;Reserves may be divided into developed and undeveloped,and contingent resources is classified into to be developed and temporarily untapped;Difficult-to-produce reserves include crude oil and natural gas.
