摘要: 扎纳若 尔凝析油气田是哈萨克斯坦共和国西部的一个大型油气田,发现于1978年,1983年起陆续投入开发。从油气田地质、开发特征出发,分析了影响油气田开发的主要因素。提出了改善开发效果的对策,即:加强人工注水,保持合理的地层压力水平;逐步完善加密开发井网,提高储量动用程度,使之达到合理的开采速度;选用合理的避水、避气厚度,进行油水井补孔,提高油藏剖面上的动用程度;适时转换采油方式,增大生产压差,保持稳产;采用有效的增产增注措施,保持旺盛的开采能力;适时开发气顶,取得最佳效益等。实践证明,这些对策是有效的。

Abstract: Zhanazhol (Ka Haxon) 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 efcts,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 efects of all such proposed measures have been proved by field practices.

Key words: Kazakhstan, condensate oil-gas field: oil ring, gas cap, well pattern, development effect
