摘要:

2010年修订后的SEC准则明确提出了可以利用“可靠技术”突破传统的以井控程度和测试成果为基础的证实储量评估模式。根据中国石油天然气股份有限公司十多年评估实践,总结提出了国内常用的4类可靠技术,包括压力系统确定流体界面、试井技术确定最大供油气范围、地震技术预测砂岩厚度及测井技术解释油气层等应用于扩大证实储量评估范围,同时总结归纳了应用于上市储量评估时对各项技术的基本要求,以及必须提供的成功案例的数量,从而满足“可靠技术”提出的与之对应的“可重复性”“一致性”“具有统计意义的证据”及“未来储量具有可增长性”的要求。深入理解SEC准则对可靠技术的相关要求,对各石油公司上市储量评估工作具有重要的指导意义。

Abstract:

The SEC standard revised in 2010 definitely puts forward a new mode to estimate the newly discovered reserves by utilizing reliable techniques instead of the traditional mode that is based on the well-control extent and testing result. Based on the PetroChina's estimation practice for more than ten years, four types of reliable techniques frequently used by domestic oil companies to broaden the estimation scope of the proved reserves were summarized, i.e. to determine a hydrocarbon-water contact with pressure system, to determine the biggest oil/gas supply radius with well testing, to forecast a sand thickness with seismic technology and to interpret pay intervals with logging. Meanwhile, the basic requests for various techniques applied to the marketing reserves estimation and the number of successful cases provided compulsorily were summarized in order to meet the prerequisites of "reliable techniques", such as "consistency", "repeatability", "evidence with statistic significance" and "increasable future reserves". Therefore, an intensive understanding on relevant requirements of the SEC standard for reliable techniques is of great directive significance in the marketing reserves estimation of various domestic petroleum companies.

Key words: SEC standard, reserves estimation, reservoir boundary, proved reserves limit, reliable techniques
