Abstract: This paper introduces the research and field application of technology for establishing short and wide fractures in terms of parameters optimization, horizontal fractures desanding, fracturing fluid, high sand ratio string and so on. Fracture parameter theory presents the optimum fracture penetration ratio and flow conductivity of different well pattern and at different formation conditions, and thus provides quantitative theoretical basis for fracturing technology of short and wide fractures; high sand ratio string, with its peculiar structure and performance, has met the technological requirements such as high sand ratio,fracturing multilayers wlth 1 string trip, capable of reverse clean-up and so on, and thus provides necessary technical support for the implementation of short and wide fractures technology. Field test has proven that this technology can control the radius of fracture within 19~25 m, can make the propping width of the fracture attain 2. 5 times of the conventionalfracturing technology at the same fracturing scale.
