摘要/Abstract

摘要： 油气经济可采储量是油公司的核心资产，深化油气经济可采储量评价与管理研究，对提升储量管理整体水平、推进油气勘探开发一体化及油公司提质增效具有重要意义。文章分析了2005—2020年全国油气探明储量状况，揭示新增探明地质储量呈高峰增长，而新增探明经济可采储量总体呈下降趋势，探明未开发储量规模不断增大，但有效开发难度越来越大等主要问题。产生问题的主要原因包括：勘探储量考核指标对经济可采储量重视不够，经济可采储量评估规范未得到有效落实，评价方法存在技术瓶颈，存量累计误差大。为此需要突破经济可采储量分类的核心地位瓶颈，突破经济可采储量评价的技术瓶颈，突破经济可采储量的管理瓶颈。建议：（1）油公司建立适合自身地质条件和生产经营特点的以经济可采储量为核心的分类系统；（2）建立商业油气流标准图版；（3）有机融合各类评价单元；（4）建立类比油气藏序列，加强类比法的应用；（5）简化国家层面的评审；（6）转变国家层面管理职能；（7）建立存量储量年度动态更新制度；（8）建立全生命周期项目管理与团队合作理念；（9）建立新增探明经济可采储量业绩考核机制；（10）建立油气储量价值评估与管理体系。

Abstract: Economic recoverable petroleum reserves are the core asset of an oil company. Promoting the study of economic recoverable oil and gas reserves evaluation and management is of great significance to improvement the level of reserve management, integration of oil and gas exploration and development, and a company’s quality and efficiency. This article analyses the conditions of China’s nationwide proved oil and gas reserves between 2005 and 2020 and reveals the trends for a peak growth in proved new addition petroleum initially in-place but a decline in proved new addition economic recoverable reserves. It also points out some main problems, such as the rising scale of the proved undeveloped reserves but the increasingly high difficulty to bring those under effective development. The problems arise mainly from such areas as inadequate emphasis on economic recoverable reserves so far as the targets for reserve under exploration, the failure to effectively carry out the standards of economic recoverable reserves evaluation, the technological bottlenecks for evaluation methods, and big errors in accumulation of the existing volume. Therefore, it is necessary to break the bottleneck for the core position of economic recoverable reserves classification, the bottleneck for evaluation technology of economic recoverable reserves, and the bottleneck for management of economic recoverable reserves. It is proposed to adopt the following measures: (1) The oil company should establish the classification system that focuses on economic recoverable reserves and meets its own geological conditions and production business characteristics. (2) Formulate the standard chart version for commercial oil and gas flow. (3) Appropriately integrate evaluation units of various kinds. (4) Formulate analogous oil and gas reservoir sequences and enhance application of analogy. (5) Simplify review at the national level. (6) Transform the managerial function at the national level. (7) Establish the system for annual dynamic updates of the existing reserves. (8) Establish the conceptions of project management and teamwork over the full life period. (9) Establish the examination mechanism for performance in proved new addition economic recoverable reserves. (10) Establish the assessment and management system for oil and gas reserve.
