The geological features of sand reservoirs in Bashijiqike Formation in Keshen2 gas field in Kuqa depression were contrastively studied with those in Kela2 gas fieldthrough analysis of sequences, sedimentary facies,petrophysics,reservoir property and reservoir connectivity. The results reveal that the sequences and sedimentary facies in the two gas fields have good relationship, but their reservoir characteristics are much different, especially in the content of feldspar, petrophysics, and development of interlayers, fractures and faults. Combined with Kela2 gas field, the reservoir propertyand connectivity in Keshen2 gas field are not well, and the gas field is in the initial process of exploration and development, therefore it is essential to use for reference from the abundance geological data and perfect development technology in Kela2 gas field.

Key words: Keshen2 gas field, Kela2 gas field, Kelasu tectonic zone, geological characteristic, communication in gas field
