对历年来被Ei Compendex Web收录的我国中文石油科技期刊论文进行了统计分析，结果表明，我国石油科技期刊自1985年首次被Ei收录以来，被收录的期刊种数和论文数量从90年代中期开始呈快速增长趋势。但总体而言，Ei Compendex Web收录的中文石油科技期刊的种数还不够多，相当多的刊物被收录情况不够稳定，而被Ei核心收录的刊物种数和论文篇数则更少。分析结果从一个侧面折射出：近年来我国石油科技研究进步显著，但整体水平还有待进一步提高。

STATISTICAL ANALYSIS OF CHINESE PETROLEUM TECHNICAL PERIODICALS AND PAPERS CITED BY EI 1)

Statistical analysis of Chinese petroleum technical periodicals and papers historically cited by EI Compendex Web is conducted. The results show the amount of periodicals and papers cited by EI increase sharply from mid 1990s since Chinese petroleum technical periodical was first cited by EI at 1985. But generally speaking, the number of Chinese petroleum technical periodicals cited by EI Compendex Web is not large enough. Some periodicals are cited unstably. The number of periodicals and the amount of papers core abstracted by EI are even much less. The analysis results reflect in one side that Chinese petroleum science and technology research achieves dramatic progress in recent years, but the whole level needs to improve further more.
