Abstract
The invention discloses a valve controlled type hydraulic packer which comprises an upper connector, a center pipe, an upper rubber tube base, a rubber tube liner pipe, a rubber tube, a lower rubber tube base and a lower connector, wherein the lower end of the lower rubber tube base outside the center pipe is connected with a piston ring, a piston is connected outside the piston ring, a hydraulic cylinder is connected in the piston and outside the center pipe, and the piston ring and the piston form a hydraulic cavity with the hydraulic cylinder and the center pipe; and a control valve is arranged on the hydraulic cylinder, and a liquid inlet hole is arranged on the center pipe and communicated with the hydraulic cavity through the control valve. The liquid inlet hole of the valve controlled type hydraulic packer is communicated with the hydraulic cavity through the control valve on the hydraulic cylinder, so that flow and speed of liquid entering the hydraulic cavity of the packer are fast adjusted according to different working conditions, and accordingly packing effect is ensured.
Description
Technical field
The present invention relates to a kind of hydraulic packer, particularly relate to a kind of valve-regulated hydraulic packer.
Background technology
Present employed hydraulic packer, the flow of its feed liquor and speed mainly adopt external control, operate not to be very convenient, and are difficult to regulate timely according to different working conditions, thereby be difficult to optimize the packing effect of packer.
Summary of the invention
Technical problem to be solved by this invention provides a kind ofly can come the valve-regulated hydraulic packer of quick adjustment feed liquor flow and speed according to different operating modes.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of valve-regulated hydraulic packer comprises top connection, central tube, goes up glue tube base, packing element bushing pipe, packing element, lower rubber cylinder seat, lower contact; Wherein the upper end of central tube connects with top connection; The lower end of central tube connects with lower contact, and the packing element liner sleeve is contained in outside the central tube, and packing element is sleeved on outside the packing element bushing pipe and between last glue tube base and lower rubber cylinder seat; The lower end of the outer lower rubber cylinder seat of said central tube is connected with piston ring; Piston ring is externally connected with piston, and the piston inner central tube is externally connected with fluid cylinder, forms hydraulic cavities between piston ring, piston and fluid cylinder, central tube; Said fluid cylinder is provided with control valve, and central tube is provided with inlet opening, and inlet opening is communicated with hydraulic cavities through control valve.
As preferably, said packing element is divided into 2 to 4 sections, is provided with gasket ring between per two sections packing elements.
As preferably, the junction of said piston ring and lower rubber cylinder seat is provided with backing-up screw.
A kind of valve-regulated hydraulic packer of the present invention; Through control valve is set on fluid cylinder; Inlet opening is communicated with hydraulic cavities through control valve, so just can come the quick adjustment packer to get into the fluid flow and the speed of hydraulic cavities according to the different working conditions environment, thereby guarantee the packing effect.
