SEC剩余经济可采储量影响因素分析

SEC剩余经济可采储量直接反映上市油气公司勘探开发、生产经营形势和发展潜力.与中国技术可采储量不同,SEC剩余经济可采储量受油价、操作成本、开发形势的影响较大.在以往定性分析的基础上,选取胜利油区典型单元,定量分析了初始产油量、递减率、油价和操作成本等参数对SEC剩余经济可采储量的影响,并制作了相应图版.研究发现,在其他条件不变时,随着油价的升高,SEC剩余经济可采储量逐渐增大,但对其影响程度逐渐降低,如油价由30美元/bbl上升至40美元/bbl时,对SEC剩余经济可采储量的影响比例为24.87％;而油价由90美元/bbl上升至100美元/bbl时,对SEC剩余经济可采储量的影响比例仅为1.37％;当油价不变时,操作成本每上升1美元/bbl,对SEC剩余经济可采储量影响比例约减少1.4％.通过查询相应图版,能方便快捷地估算SEC剩余经济可采储量.

Analysis on influencing factors of SEC reserves evaluation

SEC reserves reflect the development and marketing potential of an oil company. Different from technical recoverable reserves in China, SEC reserves is more easily affected by oil price, operating cost and well performance. Based on qualitative research of other evaluators, this paper analyzed quantitatively the correlation between SEC reserves and its four main influencing factors (oil price, operation cost, initial rate and decline rate) on the basis of calculation results of typical units in Shengli Oil Company and made relative plate. A simple and feasible method to forecast SEC reserves was found herein and proved to be accurate enough by a real evaluation example.
