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.
