When we studied the relation between the fracture spacing and production rate by water and electricity analogy experiments

if the boundary range was small

the influence of the distance between the fracture and the boundary on the production would be difficult to be neglected. Actually

this relation was affected by both the fracture spacing and the distance between fractures and boundary. In order to overcome this shortcoming

we proposed a new method to extract this influence by experimental measurement and formula correction

then

to eliminate the influences of fracture and boundary distance on fracture production rate. This method reflected the real relation between the fracture spacing and the production rate

and provided effective guidance for fracturing designs.
