摘　　要：近年来松辽盆地北部深层徐家围子断陷天然气勘探取得了重大突破,2005年徐深气田提交天然气探明地质储量1 018.68×108m3。为搞好徐深气田火山岩气藏的开发工作,应用气井产能测试及压力恢复试井等资料的解释分析,对徐深气田火山岩气藏进行早期评价。建立气井产能方程,初步确定火山岩气藏气井产量和无阻流量差异较大,气藏模型类型复杂多样,储层平面分布范围有限,多数压裂井附近存在不流动边界,因此,单井合理配产和控制边底水采出是高效开发徐深气田的重要手段。As a success of natural gas exploration in Xujiaweizi faulted-depression in northern Songliao Basin in recent years, Proven geological reserves of natural gas of 101. 868 billion cubic meters were built in Xushen Gas Field in 2005. To make big progress in developing volcanic gas reservoirs in Xushen Gas Field, initial evaluation of the volcanic gas reservoirs is perfermed by applying productivity testing and pressure buildup testing data of gas well. Productivity equation of natural gas well is established. It is initially confirmed that difference between gas well production and resistless flow rate of volcanic gas reservoir is relatively great, gas reservoir types are complex and various, horizontal distribution of reservoir is limited, and immobile boundary exists around most of fractured wells, so reasonable production allocation and edge-bottom water control are important approaches to effectively develop Xushen Gas Field.
