Status of Development of Hydraulic Fracturing Technologies

This paper overviews the development of hydraulic fracturing techniques in recent years both at home and abroad.It focuses on the application and development of fracturing design optimization,fracturing fluid and prop-pant,fracture detection and fracture height control,tip screenout fracturing and refracturing technologies.Rec-ommen dations are put forward on development of frac-ture control tech nology,utilization of tip screenout frac-tur ing tech nolo gy in formations with high and medium perme ability,enlargement of application field of hy-draolic fracturing tech nolo gies and development of field real time moni tor ing tech nolo gy.
