The end to take off the sand fracturing technology

With the development of oil and gas drilling technology and a variety of the intersection of the integrated use of technology, fracturing technology application range is no longer confined to low permeable formation, middle and high permeable formation also began to use the technology to resin coated ceramic proppant development effect. When fracturing technique is applied to the high permeability formation, hope to form a short and wide fracture, and the crack control as much as possible in the range of oil and gas layer. Abroad in order to meet the special requirements, in the mid - 1980 - s end sand fracturing technology, is developed and applied to the scene quickly, the current domestic also conducted the research, and has made great progress.
