扎纳若尔凝析油气田改善开发效果的对策

生物技术特别是微生物采油技术，已经引起了石油工程技术人员的空前关注。在国内外，微生物采油技术的先导性矿场试验已初见成效，较为典型的数美国和俄罗斯，我国的吉林、胜利等油田也进行了矿场试验，增油效果鼓舞人心。同时，随着科技的发展，一些先进的微生物学研究工具已经进入微生物采油技术的研究领域，如分子生物学、示踪剂及可视化技术等已经成为微生物采油机理研究的重要工具。相关的石油烃降理论、数学模型等也取得了系列成果。微生物采油的应用也从开始的单处理逐渐向整个区块或油田发展，并见到了明显效果。

The Measures for Improving Development Effects of Zhanazhol Condensate Oil-Gas Field in Kazakhstan

Zhanazhol (Жанажол) condensate field, a big oil-gas field in western Kazakhstan, is discovered in 1978 and brought into development in 1983. This paper makes an analysis of the main factors affecting their development from geologic features and development characteristics, and puts forward the measures for improving development effects, such as enhancing water injection, keeping reasonable formation pressure; perfecting infill well patterns, improving producing reserves extent for maintaining a reasonable oil recovery rate; choosing reasonable thickness of avoiding water-conning and gas-channeling for remedial perforation to improve producing reservoir profile; making timely conversion of recovery process, augmenting producing pressure differential for stable production; adopting effective measures of production and injection stimulations for keeping higher productivity, and timely development of gas cap for best benefits. The effects of all such proposed measures have been proved by field practices.
