Hydraulic fracturing (also fracking, fraccing, frac'ing, hydrofracturing or hydrofracking) is a well stimulation technique in which rock is fractured by a pressurized liquid. The process involves the high-pressure injection of 'fracking fluid' (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants (either sand or aluminium oxide) hold the fractures open.
How does the technology be used in the oil well drilling? Usually we use the fracturing tools to do the work. The Bottom Sealing Drag Type Fracturing Tools combined with coiled oil tube is used most.
Dezhou Jingmei Petroleum Machinery Co,.Ltd has developed series of fracturing tools. Also provide technical service. Be widely accepted by the oil company. Exported to some foreign country. Received high praise from foreign clients.
Technical Principle
This technology is the combination of hydraulic sand jet perforating and annulus sand injection staged fracturing. The multiple stage perforating and fracturing can be achieved by one trip of the string and tools. The perforation can be completed by the hydraulic sand jet of the tool string. The isolation of different layers can be achieved by the set/unset of drag type bottom sealing packer. The string has been pulled out and full bore can be achieved when fracturing is finished.
