Abstract
The invention discloses a high density filled sand control hydraulic vibration device, which comprises the following parts: upper joint, upper and lower uniflow valves, wherein the upper and lower uniflow valves contain the upper and lower valve seats, upper and lower uniflow valve balls on the upper and lower valve seats, elastic pipe within baffle between upper joint and upper uniflow valve; the bottom of upper uniflow valve connects the lower uniflow valve. The invention structure is simple, which can be widely used in the oil exploitation sand control craft.
Description
One, technical field
The present invention and oil exploitation sand-preventing process device, particularly a kind of sand-proof hydraulic vibrating apparatus for high density filling.
Two, background technology
In order to make gravel packing zone increase compactness, improve sand controlling result, need to use special-purpose vibrating device to be implemented, existing mechanical vibration gravel pack technology and device, though have the function that increases the filling bed compactness, but there is following shortcoming or deficiency: 1. wellhead assembly and down-hole string complex structure need special-purpose packing tool, special well head rotating machinery and underground vibrating device and complicated fastening means; 2. working procedure is many, and the time is long, the cost height; 3. poor with conventional sand control technique matching.
Three, summary of the invention
The purpose of this invention is to provide a kind of improved sand-proof hydraulic vibrating apparatus for high density filling, shortcoming or deficiency that it can overcome effectively or avoid existing in the above-mentioned prior art, both can be supporting with traditional sand-preventing process, can increase the compactness of filling bed again effectively.
Sand-proof hydraulic vibrating apparatus for high density filling of the present invention, comprise top connection and upper and lower ball-and-seat, described upper and lower ball-and-seat comprise upper and lower valve seat and on the upper and lower single current valve ball installed, also comprise the baffle plate that the elastic tube that is connected between top connection and the last ball-and-seat and this elastic tube inner chamber are installed, the described ball-and-seat lower end of going up connects ball-and-seat down.
Wherein, described elastic tube is the pressure pipe of metal or nonmetals or the making of its composite material.
The present invention has following advantage compared with prior art:
1, technology is simple, and structure, operation are easy, can be connected with tubing string is supporting with traditional gravel pack technology, and speed of application is fast, and the time is short, and effective, cost is low.
2, owing to adopted elastic tube and ball-and-seat structure, resistance and the water hammer of utilizing the backflow of filling fluid in the filling work progress to produce by the single current valve ball, promote ball-and-seat bump inwall, and then make elastic tube produce strong vibration and swing, drive the ball seat outer wall and knock screen casing, thereby make more closely knit that pack gravel becomes under the hydraulic pressure and the double action of knocking, improve sand controlling result.
3, avoid the generation of sand plug and bridging plug phenomenon in the work progress effectively, improve filling quality.
Four, description of drawings
Accompanying drawing is a structural representation of the present invention.
Five, the specific embodiment
Consult accompanying drawing, a kind of sand-proof hydraulic vibrating apparatus for high density filling, comprise top connection 1 and upper and lower ball-and-seat 4,6, described upper and lower ball-and-seat 4,6 comprise upper and lower valve seat 5,7 and on the upper and lower single current valve ball 4,6 installed, also comprise the baffle plate 3 that the elastic tube 2 that is connected between top connection 1 and the last ball-and-seat 4 and this elastic tube 2 inner chambers are installed, described ball-and-seat 4 lower ends of going up connect ball-and-seat 6 down, and this upper and lower ball-and-seat combination can be carried out multistage being used in combination according to well oil reservoir length.
Elastic tube is the pressure pipe of metal or nonmetals or the making of its composite material, is the commercially available prod.
During use, sand-proof hydraulic vibrating apparatus for high density filling of the present invention is lowered in the sand control screen in the sleeve pipe 9.
Claims (2)
1, a kind of sand-proof hydraulic vibrating apparatus for high density filling, comprise top connection and upper and lower ball-and-seat, described upper and lower ball-and-seat comprise upper and lower valve seat and on the upper and lower single current valve ball installed, it is characterized in that also comprising the baffle plate that the elastic tube that is connected between top connection and the last ball-and-seat and this elastic tube inner chamber are installed, the described ball-and-seat lower end of going up connects ball-and-seat down.
