摘　　要：张海13-22L井为滩海张东地区的一口开发井,压裂难度大,对压裂液的性能要求比较严格,分析认清洁压裂液性能最好,主要特点是摩阻低、携砂好、对油气层的伤害小。因此决定张东地区沙二储层采用清洁压裂液技术,从张海13-22L井压裂情况可以证明这种清洁压裂液效果好,能够解除地层的严重污染,有效的改善了地层渗透能力,压裂后日注水量提高了100倍以上,为该地区的下步开发提供重要依据。Zhanghai 13-22L well is a development well at Zhangdong areas in beach,where fracturing is difficult,the performance requirements of the fracturing fluid are more stringent.It is identified that clean fracturing fluid has the best performance,the main characteristics of it are low friction,carrying sand,and a small damage to reservoir.So,it is decided that the second sand reservoir at Zhangdong areas utilizes clean sand fracturing fluid technology.By applying fracturing fluid in Zhanghai13-22L well,it is proved that its result is good,serious pollution of ground is cleaned effectively,the formation permeability capacity is improved effectively,water injection after fractured increases at more than 100 times that provides an important basis for the next step of development of this region.
