Staged fracturing sliding sleeve used for oil well and device and usage method thereof
ActiveCN103132969AEfficient miningImprove the effective oil passing areaFluid removalWell/borehole valve arrangementsEngineeringPressure controlled ventilation
A staged fracturing sliding sleeve used for an oil well comprises a sliding sleeve outer shell, an inner sliding sleeve, a blocking piece and a suppressing pressure control device. The sliding sleeve outer shell is used for being connected to an oil casing pipe, and a first fracturing hole is formed in the side wall of the outer shell. The inner sliding sleeve is fixed in the outer shell through a pin which penetrates through the side wall of the outer shell and the side wall of the inner sliding sleeve, and a second fracturing hole is formed in the side wall of the inner sliding sleeve, wherein the first fracturing hole and the second fracturing hole are staggered in a radial direction. The blocking piece and the suppressing pressure control device are arranged in the inner sliding sleeve. The suppressing pressure device comprises an actuating mechanism which is used for forcing the blocking piece to keep in an opened position, wherein the actuating mechanism enables the blocking piece to move to a closed position when the suppressing pressure control device receives a preset signal, seals an inner cavity of the inner sliding sleeve and forms pressure accumulation. When the pressure is increased to overcome shear force of the pin, the pin is sheared, and the inner sliding sleeve slides along the axial direction until the first fracturing hole aligns at the second fracturing hole in the axial direction of the sliding sleeve.

Three-colour injection moulding device
InactiveCN105415573AGuaranteed depthGuaranteed compactnessLayered productsEngineeringInjection moulding
The invention discloses a three-colour injection moulding device. According to the invention, a middle material ejection gun transversally moves by virtue of a movement track, and the position of a middle charge hole of a moulding die can be adapted through large-range transversal movement of the middle material ejection gun; after a locking device is unscrewed, a middle adapter elbow is capable of rotating with a conical head at the discharge end of the middle material ejection gun by virtue of a connector of a first elbow part, so that a middle material ejection nozzle is specifically aligned with the middle charge hole of the moulding die, and the locking device can be screwed, so that location convex bars and strip-shaped concave grooves are correspondingly buckled to guarantee no desiderative rotation of the middle adapter elbow; and after the locking device is screwed, the surface and a conical inner surface of the conical head are mutually matched to clamp elastic sealing cushion layers to seal on the contact surfaces, and external annular convex lines and internal annular convex lines can clamp the elastic sealing cushion layers at the two sides, so that the surfaces of the elastic sealing cushion layers are deformed and mutually embedded in the external annular convex lines and the internal annular convex lines, thus sealing contact areas are remarkably increased, and the sealing effect is better.
