Abstract: The difficulty and key to hydro-fracture design is how to define optimum parameters of hydro-fracture,design of hydro-fracture is different to various geology conditions.According to materials of hydro-fracture in Shuanghe oil-field,the article analyzes factors which affect output of oil well,these factors include physic feature of oil zone,methods of hydro-fracture,ratio pulled,quantity of sand absorbed,length of perforation and so on.It calculates relations of fixed quantity about output corresponding thickness of oil zone and ratio pulled of hydro-fracture corresponding height of crack,it also gives relation of fixed properties on quantity of sand absor bed corresponding out put of oil well.
