摘要:

中国以往的油气资源评价侧重于对地质资源量的评价,如何由地质资源量得到可采资源量一直是油气资源评价中的难题。为此,在新一轮(2003—2007年)全国油气资源评价中,对油气资源可采系数开展了专项研究。首先,将国内石油评价单元划分为中生代坳陷高渗单元、古近纪与新近纪断陷盆地复杂断块高渗单元等24种类型,将天然气评价单元划分为克拉通盆地古隆起单元、前陆盆地冲断带单元等16种类型。然后,在对油气藏地质特征解剖和开发特征描述基础上,主要采用统计分析方法和类比分析方法,分析了评价单元地质、开发特征与可采系数之间的关系,进而建立起各评价单元油气资源可采系数的取值标准,为可采资源量的计算提供了依据和标准。

Abstract:

The past petroleum resource assessments concerned the evaluation of in-place resources in China,so it was difficult to calculate the recoverable resources using the in-place resources. During the activity of China national petroleum assessment (from 2003 to 2007), the recoverable coefficient of oil and gas resources was studied specially. At first, on the basis of the geological features, 24 types of oil assessment units and 16 types of natural gas assessment units were classified, such as the high-permeability unit in the Mesozoic depression, the high-permeability unit of complicated fault blocks in the rift basin, cratonic basin palaeo-high, foreland basin thrust fault. Secondly, the geological and development characteristics of reservoirs were investigated. The relationship among the unit geology, development features and recoverable coefficient were analyzed by adopting the statistic and analog methodologies. At last, the recoverable coefficient standards for the assessment units of oil and gas resources were established. The recoverable coefficient standards of oil and gas resources were used to calculate the recoverable resources.

Key words: oil and gas resources, recoverable resources, assessment unit, recoverable coefficient, assessment standard
