Results of comparative experiments with different ahead fluid.

Experiment	Tri-axial pressure (MPa)	Experimental fluid	Degree of fracture diversion	Relationship between hydraulic fracture and natural fracture	Fracture complexity
	2					25/20/10		High	Crossing	High
3	25/20/10		Low	Diversion	Low
4	25/20/10		High	Diversion	Medium
