摘　　要：准噶尔盆地克拉美丽气田为新疆油田近年来发现的储量为千亿立方米大型整装火山岩气田,自投入开发以来,就出现气井产水量上升快、产能下降快、储量动用程度低等问题,特别是产水井逐步增多,已严重制约了气田的生产,水的治理已成为保持气田稳产最迫切需要解决的问题。为此,开展了气水分布规律、产水类型、产水特征、水侵机理等研究,初步认为,克拉美丽火山岩气田水侵模式主要有水锥型、纵窜型和纵窜横侵型3种类型。根据不同的水侵模式,开展了治水对策研究,并对出水最严重的滴西18井区气藏进行了治水试验,取得了良好的效果。Kelameili gas field of Xinjiang Oilfield Company is a large and integrate volcanic gas field with proven one hundred billion cubic meters reserves in Junggar basin.Since putting into development,it was faced with such problems as water cut rising fast in gas wells,productivity declining and low degree of reserves producing,etc.In particular,the gradual increase of water-yielding wells has seriously restricted the gas field production.Hence,water control has become the most urgent problem to be solved to keep the stable gas production.Aiming at such phenomena,this paper studied the gas and water distribution regularities,water-yielding patterns and features as well as water invasion mechanism.It is preliminarily believed that Kelameili volcanic gas field mainly has three water invasion types：water coning,vertical water channeling and vertical channeling-lateral invading ones.According to these different water-invading patterns,this paper proposes the water control measures,performs the water control tests of the gas reservoir in Dixi-18 well block where the water-yielding is the most serious,and the results are satisfactory.
