1998年Surjaamadja第一次提出了水力压裂的思想和方法,水力喷射压裂技术集水力喷砂射孔与水力压裂于一体,这种技术实现了精确的射孔与压裂,同时不需要机械封隔,降低了地层的污染,节省了作业费用和时间。通过水力压裂和水力喷射压裂的对比研究,分析了水力喷射压裂的起裂机理,得到了其起裂压力的计算公式,进一步指导水力喷射压裂参数的优化。
Surjaamadja first proposed the concept and method of hydraulic fracturing in 1998. The hydraulic jet fracturing technology integrates hydraulic blasting perforation with hydraulic fracturing. This technique achieves precise perforation and fracturing without the need of Mechanical packing, reducing the formation of pollution, saving operating costs and time. Through the comparative study of hydraulic fracturing and hydraulic jet fracturing, the initiation mechanism of hydraulic jet fracturing is analyzed, and the formula of fracturing initiation pressure is obtained, which further guides the optimization of hydraulic jet fracturing parameters.
