Introduction to Frac Trees

Big oil field companies indicates that frac tree is an important part of fracturing equipment, which is mainly composed of multiple fracturing sluice valves and fracturing heads.

Main functions of frac trees:

Input frac trees from multiple fracturing manifold into the fracturing head, and then let them enter the well bottom through the fracturing sluice valve to fracture the rock layer. The fracturing operation is controlled by the switch of the fracturing sluice valve.

Applications of frac trees:

According to some big oil field companies, when the oil well outputs reach a certain stage, the productivity and permeability will decrease. In order to improve the oil drainage capacity and increase the outputs of oil wells, fracturing technology was invented.

Fracturing methods can be divided into hydraulic fracturing and high energy gas fracturing. Hydraulic fracturing involves injecting high-speed fluid into a well with a high-pressure pump truck on the ground. The high pressure at the bottom of the well is used to break the cracks in the reservoir rock. To prevent the pump from stopping running, the pressure will drop and the crack will close on its own. In the fluid that is injected after the formation fracturing, sand mixes with sand, and the density is several times as high as that of the formation. The sand enters the cracks with the fluid and stays there forever. The cracks are open, which improves the oil flow environment in a long run.

Currently, the hydraulic fracturing technology has been very mature and the well stimulation effect is obvious, which makes it become the preferred common technology. Hydraulic fracturing technology is especially suitable for small oil flow channels. In another words, this technology has particularly strong effect on the reservoir with low permeability.

Some big oil field companies, like SHANDONG SAIGAO GROUP CORPORATION adopts the international advanced technology. The main part of our fracturing is the fracturing valve, which has obtained national invention patents and utility model patents. The quality of our products deserves your trust.
