摘　　要：使用Petrel软件建立了威远20XHXX平台的三维地质模型,优化了页岩气水平井分段压裂参数。研究表明不同的压裂段长与射孔簇数有合理的匹配关系,而且存在最优的用液强度和加砂强度,随着压裂段长、射孔簇数的增加,需要合理调减水平井间距。针对威远页岩气水平井压裂,建议增加射孔簇数缩小簇间距,提高施工排量,不同压裂段长时采用优化的用液强度和加砂强度值。The three-dimensional geological model of Weiyuan 20XHXX platform is established by using Petrel software,and the segmented fracturing parameters of shale gas horizontal wells are optimized.It is shown that there is a reasonable matching relationship between fracturing section length and perforation cluster number,and there is an optimal fracturing fluid flow-rate and proppant concentration.With the increase of fracturing section length and perforation cluster number,it is necessary to reasonably reduce the horizontal well spacing.For the fracturing of Weiyuan shale gas horizontal wells,it is suggested to increase the number of perforation clusters,reduce the cluster spacing,improve the construction displacement,and adopt the corresponding optimized fracturing fluid flow-rate and proppant concentration for different fracturing section length.
