【 摘 要 】

Physical simulation of hydraulic fracturing based on the feature of shale gas reservoir is an effective means to comprehend fracture geometry and extension mechanism, which is also one of the most effective methods for shale gas reservoir reconstruction. Take hydraulic fracturing construction as reference and select critical factor for object, shale gas hydraulic fracturing experimental system was designed. The system consists of true triaxial module, hydraulic servo pump module and acoustic emission module. By setting up different parameters of fracturing in simulation experiment, the influence of parameter factors on hydraulic fracturing effect is studied. The results show that type and quantity of perforation, size and direction of in-situ stress, fracturing fluid displacement and other parameters have different influence on the fracturing effect. This experiment provides a certain theoretical basis for shale gas hydraulic fracturing technology in construction site.
