摘　　要：在射孔完井效率评价中，有很多影响我们进行评价的因素。通过在实践中反复探索、验证，提出了利用储层系数消除储层差异影响并对油气藏动、静态参数综合分析以及利用评价油气层损害的产率比（ＰＲＪ）和表皮系数（Ｓ）评价射孔完井效率的两套方法。经过对磨溪气田雷一１气藏的射孔完井效率评价，效果明显。在评价中我们还发现评价结果对射孔优化设计在现场应用的正确性有决定性的作用，对射孔弹的研制具有指导作用。两种方法都能对射孔完井效率进行正确评价，第一种方法更适合在现场大量使用。There are many influence factors in perforated completion efficiency evaluation.Through exploring and verifying in practice for many times,two methods are proposed in the paper,one is to eliminate the influence of reservoir difference between wells by use of the reservoir coefficient and to carry out a comprehensive analysis of dynamic and static parameters of oil and gas reservoir;the other is to evaluate the perforated completion efficiency by productivity ratio and skin factor which are used for appraising oil & gas formation damage.Through the perforated completion efficiency evaluation of Lei11 gas reservoir in Moxi field,it is proved that its result is satisfying.The evaluated result is also very important for the application of the optimal perforation design to the practice and for the development of perforating charge.Both the methods can be used for correctly appraising the perforated completion efficiency and the first is more suitable for being largely adopted in the fields.
