Abstract: Zhanazhol (Ka Haxor) 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 in-jection, keeping reasonable formation pressure; perfecting infll well pattems, improving producing reserves extent for maintain-ing a reasonable oil recovery rate; choosing reasonable thickness of avoiding water. conning and gas-channeling for remedial per-foration to improve producing reservoir profile; making timely conversion of recovery process, augmenting producing pressure dif-ferential for stable production; adopting effective measures of production and injection stimul ations for keeping higher productiv-ity, and timely development of gas cap for best benefits. The efects of all such proposed measures have been proved by field practices. .
