Abstract: Kelameili gas field is the first volcanic giant gas field with OGIP over hundred billion cubic meters found in Junggar basin. This paper presents the well test data analysis, open flow potential estimation and its influencing factor study, reasonable production determination of single well and summary of production performance characteristics, discussing the well test and production test characteristics of this volcanic gas reservoir, which provide basis for rolling development of this area and stable yield of the gas reservoir.

Key words: volcanic gas reservoir, well test characteristic, production test characteristic
