摘要
高渗透层压裂技术是水力压裂的一个重要突破，它包括从中渗透率到高渗透率储层的压裂技术。压裂机理是要求压裂后产生的地层裂缝建立短而宽的高导流裂缝，有效地增大泄油半径。文中介绍了高渗透层压裂的选井原则、技术要求和措施。高渗透层压裂前必须进行测试压裂，其关键技术是作业中应用了端部脱砂技术，应用实例论证了该技术的增产效果。
Fracturing technique in high permeability formation is an important breakthrough in hydraulic fracturing,It requests to build shorter and wider high conductive fracture to increase effectively drainage radius.The paper introduces principle of well selection,technical requirements and measures of fracturing in high permeability reservoir.Fracturing testing is conducted before fracturing.The key of this fracturing is the use of tip screen-out technique.Its stimulation effect is demonstrated by example.
