1、中文摘要论文题目:榆林南区山2气藏气井产能核实及开发指标预测专业:油气井工程硕士生:王删㈣幽习缝指导教师:聂翠平(签名)一李天太(签名)摘要榆林南区山2气藏是低渗透气藏,从气田高效开发思路出发,强化气田开发动态分析是非常有必要的,气田开发动态分析的核心是气井产能核实和开发指标预测。本文应用稳定“一点法”进行气井产能核实,该方法可以节约大量的测试费用。同时求得了准确和有效的单井无阻流量。稳定“一点法”求气井产能的关键是计算压力参数,本文优选了井底流压计算模型,修正了计算的井底静压,并求得气井无阻流量。本文应用数值模拟技术来预测气井开发指标
2、,采用了Schlumberger公司的Eclipse2005a油气藏数值模拟软件预测了榆林南区的开发指标。研究结果表明,适用于低渗透气田产能方程为二项式产能方程,榆林南区山2气藏,处于开发中期阶段,可以通过生产动态来计算气井产能,应用经验法和采气曲线法进行配产;结合生产动态和静态地质资料进行产能核实。计算结果表明:I类、II类气井具有较长的稳产期和较高的产量,III类气井几乎没有稳产期,日产气量不足1万方。本文应用数值模拟技术对榆林南区山2气藏进行储量拟合和生产动态拟合,在此基础上,给出榆林南区山2气藏开发指标。研究结果对榆林南区山2气
