Abstract
The utility model discloses an automatic vibrating filling tool, the structure comprises a central pipe, a rinsing pipe, a wire-wrapped pipe and a plug; wherein the rinsing pipe is connected with a vibrating device which consists of a rinsing pipe connector, a nut, an eccentric piece, a packing auger device and a vibrating outer tube. The outer tube is connected with the rinsing pipe, the packing auger is arranged in the vibrating outer tube. The further outer of the utility model has a central pipe and the wire wrapped pipe in turn. The tool uses motive energy of the filling gravel liquid with sand to make the gravel generate the vibration, to make the gravel filing more tight and efficient. The tool is used for the sand prevention craftwork of the oil exploitation well, in particular used for the wire wrapped pipe gravel prevention craftwork.
Description
The utility model relates to oil exploitation sand-preventing process equipment, relates in particular to a kind of self extinguishing type vibra-pack instrument.
What petroleum industry publishing house published in March, 1991 " has announced a kind of " vibration gravel filling sand prevention instrument " in oil recovery technique handbook one book.Structure is every a segment distance slide block to be installed on the washing pipe, and slide block clashes into screen casing when down-hole string is rotated on ground, makes screen casing produce vibration.Its objective is that the gravel that makes filling is tangible, fine and close, sand controlling result is good.But this instrument exists the power of slide block bump screen casing and needs the ground preparation, equipment complexity, shortcoming or deficiencies such as operation inconvenience.
The purpose of this utility model provides a kind of self extinguishing type vibra-pack instrument, overcomes fully and has avoided above-mentioned shortcoming and defect of the prior art, and its equipment is simple, and is easy to operate, remarkably productive, and cost is low.
The purpose of this utility model reaches like this:
The self extinguishing type vibra-pack instrument that comprises washing pipe, wire-wrapped screen, central tube and plug connects a vibrating device on its washing pipe, it comprises washing pipe joint, nut eccentric block, auger device and vibration urceolus.The both sides of its vibration urceolus are connected with the washing pipe joint respectively, and the auger device is contained in the vibration urceolus.
The purpose of this utility model can also reach by following measure:
The washing pipe joint is a tubular structure, in the one end axle sleeve is arranged, mounting center axle and the liquid flow hole road is arranged on the axle sleeve.The auger device is the auger that helical blade is installed on the central axis, and its central axis is installed in the washing pipe joint axle sleeve, and eccentric block is housed on it.Eccentric block is the reguline metal member of a deviation of gravity center central axis, is installed on the central axis.
The drawing of accompanying drawing is described as follows:
Accompanying drawing is the utility model example structure sectional plan view.
The utility model is described in further detail below in conjunction with accompanying drawing:
Vibration urceolus 11 two ends link to each other with washing pipe joint 5,12 respectively, and auger device 10 devices are in vibration urceolus 11, and its central axis 9 two ends are installed in the axle sleeve 6 of washing pipe joint 5 and 12, and are and are slidingly matched.Eccentric block 8 is contained on the central axis 9, and fixes with nut 7.Washing pipe joint 5,12 connects washing pipe 1 respectively.The vibrator of said structure is packed in the central tube 3, assembling wire-wrapped screen 2 on the central tube 3, the lower end connects plug 4.
During construction, load fluid enters annular space between wire-wrapped screen 2 and the sleeve pipe from central tube 3, wherein gravel deposition is in this annular space, and the load fluid of sloughing gravel flows out from the slit of wire-wrapped screen, enter and return from the lower end of washing pipe 1 and enter the self extinguishing type vibra-pack instrument, the hydraulic shock auger device 10 that enter this moment also forces its rotation.The central axis 9 of the auger device 10 of rotation drives eccentric blocks 8 rotations, produces centrifugal and makes washing pipe 1 produce vibration, and 1 centre of percussion pipe 3 of the washing pipe of vibration makes its generation vibration force, and this vibration force is passed to the gravel tissue by wire-wrapped screen 2.Under the effect of mechanical oscillation and fluid wave, just make gravel particle produce vibration like this, the arrangement that reaches pack gravel is tightr, and the space is littler, the construction efficient energy-saving.
The utility model has following characteristics compared with prior art:
1, simple in structure, easy to operate, safe and reliable;
2, pack gravel layer compact structure is remarkably productive;
3, an energy is multiplex, and energy-saving and cost-reducing, cost is low, high efficiency.
