中国与SEC储量评估差异分析——以元坝长兴组元坝103H井区长二段气藏为例

摘要

Three main petroleum companies in our country have successfully come into the SEC in succession since 2000, and the reserve estimations on oversea market have been made based on SEC rules. The differences of reserve estimation concept, classification and purpose lead to the differences of estimation results between domestic and SEC rules. A case study of gas reservoir has been carried out in the 2nd section of the Changxing Formation, well Yuanba 103H. The determination of gas-bearing area and effective thickness based on domestic and SEC rules has been compared.%2000年以来,我国三大石油公司陆续在美国证券交易市场成功上市,上市储量评估采用的技术规范是SEC准则.国内外储量评估内涵、分类和目的有所不同,使国内外评估结果存在差异.该文以元坝103H井区长二段气藏为例,就国内规范和SEC准则在容积法评估储量过程中确定含气面积、有效厚度等参数取值的具体方法逐一对比分析.
