摘要 为了研究徐家围子断陷营城组天然气成藏规律,在认识气源断裂与生、储、盖发育特征的基础上,采用空间组合和叠合分析的方法,对气源断裂与生、储、盖空间配置及对天然气成藏的控制作用进行了分析。研究认为营城组天然气藏属于气源断裂沟通的下生、上储式气藏,气源断裂及生、储、盖层空间配置对天然气成藏具有控制作用,主要表现为断-源空间配置控制着天然气成藏范围,断-盖空间配置控制着天然气成藏层位,断-储空间配置控制着天然气成藏部位。 In order to study the accumulating laws of Yingcheng-Formation gas reservoir ( K1yc ) in Xujiaweizi Fault Depression, on the bases on the understandings of the gas source-rock faults and developed characteristics of the source rock, reservoir and cap rock, with the help of the methods of space combination and overlap, the analy- ses of the space matching among the faults, source rock, reservoir and cap rock and moreover the controlling action of the faults on the gas reservoir accumulation are conducted. The researches show that the gas reservoir in the for- mation belongs to that with lower source rock and upper reservoir, there are a certain controlling action of the space matching among the faults, source rock, reservoir, cap rock on the gas reservoir accumulation, the main details are shown as follows : the fault-source rock matching controls the size of the gas accumulation ; the fault-cap rock matching determines the horizon of the gas accumulation ; the fault-reservoir matching dominates the part of the gas accu- mulation.
