Abstract: Hydraulic perforation jet fracturing is an innovative stimulation technology, which integrates hydraulic perforation with jet adding-sand fracturing. A special hydraulic jet tool is adopted to perforate and fracturing is carried out directly at jetting state. This technology is suitable for multi-interval fracturing in horizontal well, as well as single or multi-interval fracturing in vertical well. Field application indicates the technology has reduced operation period and cost, improved the job security for horizontal wells. Higher conductive fractures near borehole zones are created compared to traditional fracturing for vertical well, which is favorable to production performance. The technology characterized by high efficiency, economic, safety and obvious stimulation capacity will have considerable influence on the development of low permeability oil/gas fields.
