摘　　要：油气井进行压裂后,裂缝体积计算对评估其增产有效性、压裂后油气井产量预测是非常重要的。由于油气储层岩石特性和压裂过程的复杂性使得确定裂缝的体积具有很大的挑战性。对储层进行压裂改造时,通常用地面或井下微地震进行施工监测,然后计算压裂改造体积,但不能计算裂缝的体积。文章基于示踪剂测试,提出了注气井的压裂裂缝体积拟合方法,总结了该方法的优点及适应性,并在玛北油田玛131井区开展了实际应用,结果表明,此拟合方法可用于优化气驱驱替速度和驱替PV数,对后续提高气驱开发效果提供指导意见。After fracturing, fracture volume calculation is very important to evaluate the effectiveness of stimulation and predict oil and gas production. Because of the rock characteristics of oil and gas reservoirs and the complexity of fracturing process, it is very challenging to determine the fracture volume. When fracturing the reservoir, surface or downhole micro-seismic monitoring is usually used, and then the stimulated reservoir volume(SRV) is calculated. But the fracture volume cannot be calculated. Based on tracer monitoring, this paper puts forward the calculation method of fracture volume of gas injection well, summarizes the advantages and adaptability of this method, and carries out practical application in block Ma 131 of Mabei oil field, which can be used to optimize the gas drive displacement speed and displacement PV value, and provide guidance for improving gas drive development effect in the future.
