摘　　要：液态CO_2加砂压裂技术作为一种前沿的无水压裂技术,国内现场试验不断取得重要进展,液态CO_2压裂施工管柱沿程摩阻计算也逐渐显现其重要性。通过矿场试验,验证了S.M.Campbell等人液态CO_2压裂液摩阻计算图版,得到了易于工程应用的拟合计算公式。与Lord等人的清水摩阻计算模型比较,为液态CO_2压裂液摩阻快速评价取得直观认识。Fracturing with sand and liquid CO_2 is an edgeleading water-free fracturing technology,important advancements are continuously achieved at the domestic field tests,it is more and more important to calculate the friction along the tubing string during liquid CO_2 fracturing. The field tests have proved the friction analysis chart for liquid CO_2 fracturing fluid,which is developed by S. M. Campbell et al. and a fitting calculation formula for engineering purpose is developed. Through comparison with the clear water friction calculation model by Lord et al.'s,a rapid evaluation of liquid CO_2 fracturing fluid friction can be perceived directly.
