摘　　要：概述了国内外重复压裂、多薄层压裂及多裂缝压裂的研究动态;介绍了3种新型压裂液体系和6种新型支撑剂,以及清水压裂技术、浮式支撑剂压裂技术、端部脱砂控缝高压裂技术与水力喷射逐层压裂4种新型压裂工艺技术。认为要提高油气井产量和采收率,亟需改进与完善常规压裂工艺技术,有机整合储层、液体、支撑剂和工艺技术。建议加强对超低密度且高强度支撑剂以及超深井、水平井加砂压裂的研究。In this paper,a research on refracturing,multiple thin-layer fracturing and multiple-crack fracturing at home and abroad is presented;moreover,3 new fracturing fluids,6 new proppants and 4 new fracturing technologies including water-fracturing,floating proppant fracturing,fracturing of end sand out and fracture height control,hydrojet fracturing layer by layer are also illustrated.It's necessary to improve conventional fracturing technologies and to integrate reservoir,fluid,proppant and the technologies in order to increase productivity and recovery for oil and gas wells.Suggestions on the proppant with ultra-low density and high strength as well as the sand fracturing of ultra-deep and horizontal wells are also proposed.
