Abstract: The reservoirs in Jilin Oilfield mainly consist of low and ultra-low permeability and fractured sandstone ones, with structural and lithologic oil pool as the main part. With an exploration history of 50 years, from the early discovery and exploitation of simple structural oil pools to recent complex lithologic ones, a series of reservoir characterization support techniques with local features have been developed. The reservoir characterization techniques, which are typical and practical, could represent the general technical status of the developmental system of the Oilfield. This research, based on the development of reservoir characterization techniques and its application in the oilfields, takes an overview on the history and effect of this technique. And it is also a reflection of the general history of petroleum development techniques of Jilin Oilfield, as well as a guide for its future development.

Key words: Jilin Oilfield, technical development, reservoir characterization, low permeability, lithologic oil pool

摘要： 吉林油田多是以裂缝性中低渗—特低渗透砂岩储层为主的构造—岩性油藏,它从初期简单构造油藏的发现、开发到目前的复杂岩性油藏的规模、有效开发,经历了50年的发展,逐步形成了具有地方特色的低渗透储量有效动用的配套技术,其中,油藏描述技术的发展最为典型而又有实效,代表了整个油田开发技术发展的水平与高度。文章回顾了油藏描述技术的发展历程及其在油田开发中所起的作用,提出了今后需要进一步研究的一些问题。
