摘　　要：川东沙坪场石炭系气藏为川气东输工程的主力气藏,地质储量382.54亿方。从1998年3月投产至2010年7月,沙坪场石炭系气藏共有生产井21口,累积产气达到131.7亿方,采出程度为34.4%。目前,气藏产水井已有5口,累计产水量54万方,严重影响了气井产量。笔者结合气藏地质情况,动态数据综合分析了气藏产水情况,各产水井产水特征和水侵途径,并进行气藏水侵治理措施探讨。Shapingchang Carboniferous gas reservoir in eastern Sichuan contains 38.254 billion cubic meter gas geological reserves,which is the main gas reservoir of the Sichuan-East Pipeline Project.Since production began in March 1998 till July 2010,the gas reservoir has had 21 production wells,while cumulative gas production is 13.17 billion cubic meter and the recovery percent comes to 34.4%.At present,five wells produce formation water,and cumulative water production is 540 thousand cubic meter,which seriously affects productivity.Combining reservoir geology and dynamic data,this article comprehensively analyzes water invasion characteristics and water preventing methods.
