Abstract: To fulfill the necessary of large scale staged fracturing operation in the shale gas horizontal wells, the main fracturing equipment (fracturing units) was optimized according to the concrete requirements of construction well. And then a series of accessorial equipment were matched such as fracturing fluids blending system, low pressure fluids supplying system, vertical sand tanks. The optimized equipment and technology meet the requirements of large scale staged fracturing operation in the shale gas horizontal wells, which is characterized by high pumping rate, large fluids volume, huge proppants volume, various fluids and various proppants involved and long operational time. The new technique was successfully applied in wells Fuye HF-1, Pengye HF-1, and Yanyeping-1. So experiences have been accumulated on the large scale shale gas horizontal wells fracturing equipments outfitting and application, and services capability on the large scale shale horizontal wells stimulation have been enhanced. For ‘well factory’ model of shale gas development in the future, fracturing equipments outfitting and technologies at present are fallen behind the requirement, which need to be improved.
