Abstract
The utility model discloses an underground sediment filtering device for a hydraulic packer. The underground sediment filtering device for the hydraulic packer is used for preventing impurities inside a pipe column from blocking a hydraulic channel and then causing construction abnormal conditions of the hydraulic packer in the construction process of the underground hydraulic packer. The underground sediment filtering device for the hydraulic packer comprises an inner pipe and a plugging head. The top end of the inner pipe is sequentially connected with a filtering mechanism and an inner pipe top cover, the inner pipe is connected with the plugging head, the sedimentation annulus is formed among the inner pipe, the plugging head and an oil pipe, and then the impurities in construction liquid are separated from the hydraulic channel of the packer. The underground sediment filtering device for the hydraulic packer is installed in the oil pipe above the hydraulic packer, enables the construction liquid entering the packer through the underground sediment filtering device to meet the purity degree requirement of construction, guarantees that liquid pressure inside the construction pipe column to be transmitted to a hydraulic cylinder of the packer, guarantees that the hydraulic packer works normally, improves the construction effect and safety, and lowers the work risk.
Description
Technical field
The utility model is the working auxiliary equipment of petroleum industry underground hydraulic packing device, hydraulic packer down-hole sedimentation and filtration device particularly, the foreign material clogging hydraulic passage when preventing hydraulic packer construction in tubing string causes hydraulic packer construction abnormal.
Background technology
Oil production technology measure hydraulic packer utilizes fluid pressure to promote piston and completes; because job site environment is very complicated; be difficult to guarantee that construction liquid is definitely pure; when the foreign material clogging hydraulic passage of construction in liquid; often can cause the fluid pressure in operating tool string cannot be delivered in hydraulic cylinder or make to be delivered to the pressure decreased in hydraulic cylinder; cause various constructions abnormal, even cannot normal construction, seriously jeopardize construction safety and affect oil production technology measure construction effect.
Seriousness understanding after current packer manufacturer and production and construction unit stop up hydraulic packer is not enough, production scene does not solve any device and the measure of obstruction, normal and safety, assurance construction effect for assurance construction, develop a kind of reliable and practical filter, the construction liquid relative clean that makes to enter hydraulic packer by this device reaches the requirement of construction degree of purity, is very necessary and urgent.
Summary of the invention
The purpose of this utility model is to provide hydraulic packer down-hole sedimentation and filtration device, solve the problem of the foreign material obstruction underground hydraulic packing device in construction liquid, the liquid that makes to construct reaches the requirement of construction degree of purity, guarantee the unobstructed of hydraulic packer hydraulic channel, thereby improve the safety of construction, guarantee that construction is normal, improve construction effect.
The utility model is achieved in that hydraulic packer down-hole sedimentation and filtration device comprises inner tube and plug, on the top of inner tube, connect successively filter mechanism and inner tube top cover, inner tube is connected with plug, between inner tube, plug and oil pipe, form sedimentation annular space, the impurities by construction in liquid is outside packer hydraulic channel.
The beneficial effects of the utility model are: the utility model is installed in oil pipe above hydraulic packer, can make the construction liquid that enters packer by this device reach the requirement of construction degree of purity, guarantee that the fluid pressure normal delivery in operating tool string arrives the hydraulic cylinder of packer, guarantee that hydraulic packer is working properly, improve construction effect and safety, reduce operating risk.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
embodiment mono-
Referring to Fig. 1, hydraulic packer down-hole sedimentation and filtration device comprises inner tube 3 and plug 4, on the top of inner tube 3, connects successively filter mechanism 2 and inner tube top cover 7, and inner tube 3 is connected with plug 4, between inner tube 3, plug 4 and oil pipe 1, forms sedimentation annular space.Between plug 4 and oil pipe 1, be provided with sealing ring 5, filter mechanism 2 is filter screen or slot pipe, plays the effect of filtering foreign material.
As shown in Figure 1, working packer 6 tops connect oil pipe 1, in oil pipe 1, the utility model is installed, in the present embodiment, inner tube 3 tops are by 7 sealings of inner tube top cover, filter mechanism 2 provides flow channels for well liquid, construction liquid flows downward, enters inner tube 3 and oil pipe 1 middle cavity from oil pipe 1 top, foreign material are deposited in the sedimentation annular space that inner tube 3 bottoms and oil pipe 1, plug 4 form, liquid filters and precipitation through filter mechanism 2, the liquid of relative clean is introduced into after inner tube 3, then enters in packer 6.
embodiment bis-
Referring to Fig. 2, in the present embodiment, the top of inner tube 3 is bowed downward to U-shapedly, makes the filter mechanism 2 that is connected with inner tube 3 and inner tube top cover 7 down, and other technical characterictic is identical with embodiment mono-.
Construction liquid flows downward from oil pipe 1 top and through the U-shaped elbow on inner tube 3 tops, enters the cavity of inner tube 3 and oil pipe 1 centre, foreign material precipitation lodges in the sedimentation annular space of oil pipe 1 and inner tube 3 and plug 4 formation, clean liquid is made progress, along inner tube 3, is entered downwards in packer 6 by filter mechanism 2, thereby the construction liquid that has guaranteed to enter in packer 6 reaches construction degree of purity.
embodiment tri-
Referring to Fig. 3, in the present embodiment, the top of inner tube 3 is bowed downward to U-shapedly, and inner tube 3 is connected with plug 4, between inner tube 3, plug 4 and oil pipe 1, forms sedimentation annular space.Inner tube top cover 7 and filter mechanism 2 are not installed in the present embodiment, and other technical characterictic is identical with embodiment bis-.
embodiment tetra-
Referring to Fig. 4, in the present embodiment, the upper end of inner tube 3 is provided with liquid flow hole, on its body top, baffle cover is installed.Cylindrical, its cover body that the cover body inner circle of baffle cover is greater than inner tube 3 block the liquid flow hole in inner tube 3.Construction liquid flows downward through the baffle cover on inner tube 3 tops from oil pipe 1 top, and foreign material precipitation lodges in the sedimentation annular space of oil pipe 1 and inner tube 3 and plug 4 formation, and clean liquid upwards enters downwards in packer 6 by the liquid flow hole on its top along inner tube 3 again.
