Abstract:
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.
