摘　　要：为了满足四川盆地洛带气田开发中后期的产能需求,针对洛带蓬莱镇组储层展开精细预测研究。通过对几种反演方法的对比,最后选用模型波阻抗反演法进行储层预测。模型波阻抗反演法在储层描述方面具有精度高、细节刻画精细、区域匹配度良好等优势,能够敏锐地捕捉岩性的变化特点、准确地反映储层的平面展布与空间分布状况。In order to meet the requirements for production capacity construction in the middle and late stages of Luodai gas field,fine prediction is carried out for Penglaizhen Formation reservoir in Luodai belt.Through the comparison of several inversion methods,the model wave impedance inversion method is selected to improve the economic benefits of the gas field.The research results show that the model wave impedance inversion has the advantages of high accuracy,fine detail description,and high regional matching in reservoir description and it can sensitively capture the characteristics of lithological changes,and accurately reflect the planar distribution and spatial distribution of the reservoir.
