Fracture propagation is affected by multi-metal-veins formed by geological diagenesis in shale during the hydraulic ***,the influence of multi-metal-veins on fractures propagation remains *** solve the problem,based on the semi-circle bending(SCB)test and the extended finite element(XFEM)theory,the interaction between multi-metal-veins and fractures is *** experimental results reveal that the fractures usually deflect at the upper or lower interfaces between metal veins and rocks(*** specimen S-2),which is different from the propagation behavior of fractures in calcite ***,the fracture toughness of the specimen S-1 is 24.40%higher than that of the specimen S-2,indicating that the increasing of total thickness of multiple metal veins in-creases the resistance to the fracture vertical *** simulation results show that the increasing of the number,total thickness of veins,the modulus difference between veins and rock,the approach angle and the notch angle all increase the resistance of the fracture passing through metal *** maximum deviation distance(Dmax)of the fracture decreases with the number of veins,while thickness combination types of metal veins do not affect *** reduction of the notch angle leads to the more tortuous fracture propagation ***,we propose a new comprehensive fracture network *** networks are divided into two categories,including orthogonal fracture networks and sub-orthogonal fracture networks,and then divided into six sub-categories *** research results will provide reference for hydraulic fracturing of shale reservoirs containing multi-metal-veins.
