中国的石油公司上市成功后,储量观念正在由地质储量向剩余经济可采储量转变,其中最重要的是强调经济因素对SEC储量评估的影响。在总结净现值法评估储量的基本流程、所需经济参数基础上,探讨了经济极限产量、递减规律、油价、成本和投资等经济因素对储量评估的影响,认为油气田的自身产量递减规律决定了其未来剩余技术可采储量,而经济因素决定了剩余经济可采储量,其中油价对剩余经济可采储量影响最为明显。

Concept of reserves in China has been changing from geologic reserves to remaining economic recoverable reserves, which emphasize the influences of economic factors on evaluation of SEC reserves, since the successful public listing of Chinese oil companies in foreign stock market. Based on the basic flow of reserves evaluation with net present value method and the economic parameters needed, this paper analyzes the influences of economic factors on evaluation of SEC reserves. It is concluded that production descending pattern of the field determines remaining technical recoverable reserves, while economic factors determine remaining economic recoverable reserves, on which oil price has the most remarkable impacts.
