Abstract

With the development of Zhongyuan oilfield,the remaining oil distribution increasingly become complex,the conventional hydraulic fracturing technology already can't satisfy the need of oilfield development. In order to solve the fracturing technology problem in the deep low permeability complex well,the hydraulic jet tool was researched,anti- high shear hydraulic jet fracturing fluid was developed,the fracturing technology design and the fracturing string design were optimized. Finally,the hydraulic jet fracturing technology suited for complex well conditions in Zhongyuan Oilfield was formed. The hydraulic jet fracturing technology perfected the hydraulic fracturing technology,realized the fracturing of near water layer,complex reservoir and tube outer channeling well. It promoted the applicability and validity of the fracturing technology.
