Description
Technical field
The utility model relates to field of petroleum machinery, particularly bailing device for horizontal well.
Background technology
In field produces, due to long-term exploitation, the pressure of oil reservoir can significantly decline, and pressure coefficient can reduce to also lower than the equivalent pressure coefficient of water.In this case, use water flushing sand washing, water enters fluid flow that low pressure layer makes to return in pit shaft and flow velocity reduces.Coarse sand particles can not be defined as ground, time serious inject water can all enter oil reservoir and can not on return, cause sand washing failure, cause oil reservoir contaminated, oil well output reduce.
The mode that existing sand-bailing equipment mostly adopts one-way pipeline to pass into liquid carries out sand washing, adopt single taper head sand to shovel and carry out shovel sand, the operating efficiency of this mode of operation is lower, and the sand area of meeting of single taper head sand shovel can be larger, and resistance is relative with frictional force also can be larger.
Utility model content
The technical problems to be solved in the utility model is: in order to overcome the ineffective deficiency of prior art, provide bailing device for horizontal well.
The utility model solves the technical scheme that its technical problem adopts: bailing device for horizontal well, comprise circulating sub, sand bucket, sand-blocking pipe nipple, sand sediment pipe, centering ring and shovel sand assembly, described circulating sub is arranged on above sand bucket, two symmetrical liquid outlets are provided with above described circulating sub, sand-blocking pipe nipple and sand sediment pipe is connected with in turn below described sand bucket, described centering ring is set on sand sediment pipe, described centering ring is provided with some bar shaped pod apertures along sand sediment pipe direction, each pod apertures is all parallel with sand sediment pipe, described shovel sand assembly is arranged on sand sediment pipe one end away from sand-blocking pipe nipple, described shovel sand assembly comprises a main cone head and six auxiliary coneheads, six auxiliary coneheads are arranged for center of circle circumference is even with main cone head, be provided with into sand hole outside described main cone head, described enter sand hole be arranged between main cone head and auxiliary conehead.
Particularly, described circulating sub is threaded with sand bucket.
Particularly, described in enter sand hole cross section be ring-type, described in enter sand hole internal diameter be greater than the base diameter of main cone head.
Particularly, the height of described main cone head is greater than the height of auxiliary conehead.
The beneficial effects of the utility model are, this bailing device for horizontal well is by adopting the mode of Double-barreled circular bailing device, add the operating efficiency of this device, the friction between the pump housing and sleeve pipe effectively can be reduced by centering ring, many coneheads formula is adopted to design, shovel sand effect can be promoted, while reducing resistance, improve shovel sand efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the utility model bailing device for horizontal well;
Fig. 2 is the structural representation of the shovel sand assembly of the utility model bailing device for horizontal well;
In figure: 1. circulating sub, 2. sand block pump, 3. sand-blocking pipe nipple, 4. sand sediment pipe, 5. centering ring, 6. liquid outlet, 7. pod apertures, 8. main cone head, 9. auxiliary conehead, 10. enters sand hole.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As Figure 1-Figure 2, bailing device for horizontal well, comprise circulating sub 1, sand bucket 2, sand-blocking pipe nipple 3, sand sediment pipe 4, centering ring 5 and shovel sand assembly, described circulating sub 1 is arranged on above sand bucket 2, two symmetrical liquid outlets 6 are provided with above described circulating sub 1, sand-blocking pipe nipple 3 and sand sediment pipe 4 is connected with in turn below described sand bucket 2, described centering ring 5 is set on sand sediment pipe 4, described centering ring 5 is provided with some bar shaped pod apertures 7 along sand sediment pipe 4 direction, each pod apertures 7 is all parallel with sand sediment pipe 4, described shovel sand assembly is arranged on sand sediment pipe 4 one end away from sand-blocking pipe nipple 3, described shovel sand assembly comprises a main cone head 8 and six auxiliary coneheads 9, six auxiliary coneheads 9 are that center of circle circumference is evenly arranged with main cone head 8, be provided with outside described main cone head 8 into sand hole 10, described enter sand hole 10 be arranged between main cone head 8 and auxiliary conehead 9.
Particularly, described circulating sub 1 is threaded with sand bucket 2.
Particularly, described in enter sand hole 10 cross section be ring-type, described in enter sand hole 10 internal diameter be greater than the base diameter of main cone head 8.
Particularly, the height of described main cone head 8 is greater than the height of auxiliary conehead 9, is so just more conducive to conehead to sinciput.
Shovel sand assembly adopts many coneheads formula to design, and main cone head 8 is highly comparatively large, to sinciput sand, and on the follow-up top again of auxiliary conehead 9, can form the state that multiple spot is stressed.
Compared with prior art, this bailing device for horizontal well is by adopting the mode of Double-barreled circular bailing device, add the operating efficiency of this device, the friction between the pump housing and sleeve pipe effectively can be reduced by centering ring 5, many coneheads formula is adopted to design, shovel sand effect can be promoted, while reducing resistance, improve shovel sand efficiency.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on manual, must determine its technical scope according to right.
