Abstract
The utility model discloses an oil-extraction sand-prevention filtering device, comprising an upper joint and a lower joint. The oil-extraction sand-prevention filtering device is characterized in that the end part of the upper joint is provided with a barrel body; a sand filtering pipe connected with the upper joint is arranged in the barrel body; a middle joint is arranged on the other end of the barrel body; a rotary arm with a center hole is arranged on the lower end of the middle joint; a rotational flow body is installed between the rotary arm and the lower joint; a liquid inlet hole is arranged in the rotational flow body; a micro-porous crystallization filter is arranged at the location of the liquid inlet hole; and a sand setting plug is installed on the end part of the lower joint. The oil-extraction sand-prevention filtering device is simple in structure, rational in design, good in filterability, and capable of effectively preventing sand so as to prevent the sand from burying oil layers.
Description
Technical field
The utility model relates to technical field of petroleum extraction, relates in particular to a kind of oil recovery sand control filter.
Background technology
At present, the oil-containing geologic structure in the many oil fields of China is more loose, and it is more to contain sand in the well liquid; Many oil wells are many half a year in ordinary production, will shake out in a large number, and along with oil field well rise of water cut; Payzone shakes out seriously, adopts the conventional pumps oil pumping that sand card, sand milling and corrosion often take place, and makes the oil well pump premature failure; Cause oil well to stop production, operation is frequent, and the cost of production of crude oil improves.And general oil well uses sand control screen to prevent the generation of this phenomenon, and existing sand control installation can not prevent effectively that the part sand grains from getting into pump barrel, and is pumped down to ground, causes the stratum in debt, and sand buries oil reservoir, causes the generation of oil well stopping production phenomenon easily.
The utility model content
The utility model provides a kind of simple in structure, reasonable in design to the defective that prior art exists, and filterability is good, effective sand control, thus prevent that sand from burying the oil recovery sand control filter of oil reservoir.
For solving the problems of the technologies described above, the technical scheme of the utility model is: oil recovery sand control filter comprises top connection and lower contact; The end of said top connection is provided with cylindrical shell; Be provided with the sand screen that is connected with said top connection in the said cylindrical shell, the other end of said cylindrical shell is equipped with transition joint, and said transition joint lower end is equipped with the turning arm with centre bore; Between said turning arm and the lower contact rotary fluid is installed; Said rotary fluid is provided with inlet opening, and said inlet opening place is provided with the microporous crystalline strainer, and said lower contact end is equipped with the sand setting plug.
Said lower contact is provided with the sand setting hole that is connected with the sand setting plug.
After having adopted technique scheme, the beneficial effect that the utility model is obtained is: the utility model is simple in structure, and is reasonable in design, and filterability is good, effective sand control, thus prevent that sand from burying oil reservoir.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
Shown in accompanying drawing, oil recovery sand control filter comprises top connection 1 and lower contact 2; The end of said top connection 1 is provided with cylindrical shell 3; Be provided with the sand screen 4 that is connected with said top connection 1 in the said cylindrical shell 3, the other end of said cylindrical shell 3 is equipped with transition joint 5, and said transition joint 5 lower ends are equipped with the turning arm 6 with centre bore; Between said turning arm 6 and the lower contact 2 rotary fluid 7 is installed; Said rotary fluid 7 is provided with inlet opening 8, and said inlet opening 8 places are provided with microporous crystalline strainer 9, and said lower contact 2 ends are equipped with sand setting plug 10.
Said lower contact 2 is provided with the sand setting hole 11 that is connected with sand setting plug 10.
During use, the top connection 1 of the utility model is connected with oil pipe, the mixed liquor in the oil well is got into by inlet opening 8; The microporous crystalline strainer 9 that at first is provided with through inlet opening 8 places filters, and after filtering mixed liquor gets into inlet opening 8 backs and makes through centrifugal turning arm 6 and revolve then, thereby produces eddy flow; In this state, owing to also have small solid after filtering, and also solid is different with density of liquid; Thereby the centrifugal force that produces is different, eddy flow and interior eddy flow outside inside forms like this, and the solid particle that density is big forms outer eddy flow; Outer eddy flow moves downward along the inwall of rotary fluid 7, and the sand setting hole 11 in lower contact 2 gets in the sand setting plug 10; And interior eddy flow moves upward because of the high speed rotation forms low pressure, in the centre bore entering cylindrical shell 3 of turning arm 6, and after 4 pairs of fine sands of not separating of sand screen or sand filtration, get in the pump, and extraction ground.
The utility model is simple in structure, and separating and filtering is effective, can satisfy the sand control requirement of different wells, effective sand control, thus prevent that sand from burying oil reservoir.
Claims (2)
