It is component critically important in shale gas hydraulic fracturing process.Shale gas is developed frequently with oil formation hydraulic fracturing technology, hydraulic fracturing
Refer to the principle using liquid pressure transmission, the pump of high-pressure large-displacement on ground, by the liquid with certain viscosity to be greater than oil reservoir
The absorbent ability of institute is injected to oil reservoir, gradually increases wellbore pressure, when pressure is increased to greater than required for oil reservoir rupture
When pressure, oil reservoir just will form one or several horizontal or vertical crack, to reduce the flowing resistance of near wellbore zone
Power increases percolation ability, and oil well is made to obtain effect of increasing production.
Rising stem (RS.) sand control gate valve is made of parts such as valve body, valve deck, valve plate, valve seat, valve rods.Rotate rising stem (RS.) sand control gate valve
Handwheel, valve stem sleeve push valve rod valve plate to move up and down, by the position for observing Outside screw stem rising through handwheel type gate valve top valve rod, so that it may know valve
Aperture.For the guide plate of conventional Outside screw stem rising through handwheel type gate valve in the lower part of valve plate, the gap of valve plate and guide plate is very big.When hydraulic fracturing, fracturing fluid
A large amount of fracturing sand is often carried, fracturing sand particle is small, and for gate valve during switch, largely the fracturing fluid containing sand passes through valve plate
Gap between guide plate enters valve chamber, washes away the stop-leak compound in valve chamber；It will appear valve plate when serious and valve seat scratch, fracturing sand is heavy
