Description
Technical field
The utility model belongs to oil recovery machiner technical field, is related to a kind of oil production filter.
Background technology
At present, as many oil wells are more in normally production half a year, sand will be measured greatly, and with aqueous upper of oil well
Rise, payzone goes out husky serious, and the sand-proof sieve tube that general oil well uses, it is impossible to effectively prevent that the part grains of sand from entering pump barrel, and by
Ground is evacuated to, causes sand to bury oil reservoir, oil well stops production.
Chinese patent (notification number：CN 203925443U, the day for announcing：2014.11.05) a kind of oil production filter is disclosed,
It can prevent the grains of sand from entering pump barrel, while can deposit thin sandstone by the first screen pack and the second screen pack double filtration
In desilting pipe, but due to the capacity of desilting pipe, in actual use, it is necessary to frequently shut down and dismantle desilting
Pipe, its internal desilting is cleared up, production efficiency is greatly reduced, improves cost for oil production.
Utility model content
The purpose of this utility model is to provide a kind of oil production filter solve oil recovery process present in prior art
The middle grains of sand are easily accessible pump barrel, cause the problem of sand buries oil reservoir, oil recovery efficiency is low.
The utility model is the technical scheme adopted is that a kind of oil production filter, including outer tube and is arranged in outer tube
Inner tube, inner tube upper end are connected with outside oil pumping pipeline, and inner tube lower end is closed, and the surface of inner tube is uniformly provided with several filterings
Micropore, multiple first screen packs is provided with filtering micropore, outer pipe surface is uniformly provided with several inverted V-shaped holes, and inverted V-shaped hole is by a left side
High right the first low inclined hole and left low right high the second inclined hole connection are formed, and the junction of the first inclined hole and the second inclined hole is provided with
Second screen pack, outer tube lower end are openning shape, are socketed with desilting pipe on the outside of the outer tube bottom, the desilting ttom of pipe end is set
Diving shell pump is equipped with, the suction sand mouth of the diving shell pump is extended in desilting pipe, the sediment ejection opening position of the diving shell pump
It is below desilting pipe and opening down.
It is of the present utility model to be further characterized in that,
Desilting pipe lower edge is provided with 4~8 support bars, and the bottom of support bar is provided with the support ring of circle, support
Boxing is connected on the bottom of support bar.
The mesh of first screen pack is less than the second screen pack.
The lower end of diving shell pump is higher than the position of support ring.
The beneficial effects of the utility model are, by the setting for shell pump of diving under water, can batch (-type) startup diving shell pump,
Suction out the fine sand of deposition in desilting pipe, realize automatic block clearing, avoid frequently shutting down cleaning and caused by production efficiency it is low
Situation, reduce cost for oil production；Support bar and support ring are set so that diving shell pump is hanging, and starts the effect of protection, prolongs
Long life.
