Background technique
Waterflooding extraction is the main means that late period of oil field improves recovery ratio, is that the important of renwing stratum energy is arranged
It applies, capital equipment of the high-pressure plunger pump as oil-field flooding, in actual production, pump valve, which fails, directly affects the water filling of plunger pump
Efficiency.
Injected media used in water-flooding pump for oil field mostly uses greatly the sewage through secondary treatment at present, can from water analysis
Out, solid grain size intermediate value 41.2d(0.5 in water) μm, maximum particle diameter value, 1258 μm；The miscellaneous content 140.0mg/L of machine in water,
Median particle size 8.5d(0.5) μm, 104.7 μm of maximum particle diameter value.These data are considerably beyond GB/T9254 " automotive reciprocating pump "
Index cause water injecting pump following problems occur due to solid particle and machine are miscellaneous:
1, there is groove in combination valve valve face, poorly sealed so as to cause combination valve valve face, and serious high-pressure water-jet leakage occurs,
Combine defective valve.
2, solid phase particles enter packing and plunger friction surface, and solid phase particles damage plunger causes under piston reciprocation movement
Packing thorn leakage, plunger disabling.
In existing flood pattern, combination valve and only 3 days plunger most short out-of-service time, longest also less than two weeks, in order to
Change such case, although a large amount of research has been done from pump self structure, material by most water injecting pump producers, because of solid particle
With the miscellaneous reason of the machine each block water quality difference in oil field in addition, it still cannot improve service life short status, lead to maintenance replacement cost
It is still high.
Utility model content

The miscellaneous device and method of machine.
The purpose of this utility model is achieved in that a kind of device that oil field flood pattern is miscellaneous except machine, it is characterized in that: extremely
It less include: cyclone, the first liquid consolidates coalescer, the second liquid consolidates coalescer, cyclone inlet and process inlet piping connection；Eddy flow
Device upper outlet divides two-way by outlet pipeline, is separately connected the arrival end that the first liquid consolidates coalescer and the second liquid consolidates coalescer；The
One liquid consolidates coalescer and the second liquid consolidates coalescer respectively at least there are two exporting, and is upper outlet and lower outlet respectively, the first liquid is solid
Coalescer and the second liquid consolidate coalescer upper outlet pass through respectively pipe fitting valve connection communicated with water lines up to standard；First liquid coalesces admittedly
Device and the second liquid are consolidated under coalescer to export to connect by pipe fitting valve respectively to be communicated with backwash water blowoff line.
The process inlet pipeline and cyclone inlet lead to bypass line by pipe fitting valve, bypass line with reach
Mark water lines are communicated by pipe fitting valve.
The cyclone lower end outlet connection blowoff line.
First liquid consolidates coalescer and the second liquid consolidates coalescer upper outlet and passes through pipe fitting valve and backwash tube respectively
Road connection.
There is backwashing pump in the backwash tube road.
The utility model has the advantages that: sewage carries out liquid into cyclone and consolidates pre-separation, isolate through process inlet pipeline
The solid particle of 50um or more, then cesspool is discharged by blowoff line；Containing 50um sewage below going out through cyclone apex
Water lines consolidate coalescer into the first liquid or the second liquid consolidates coalescer and carries out solid-liquor separation, separate the above solid particle of partial size 5um,
Enter water injecting pump through water lines up to standard；Coalescer is consolidated to the first liquid in process flow or the second liquid consolidates coalescer and is equipped with backwash stream
Water with pressure the first liquid of feeding is consolidated coalescer or the second liquid is consolidated coalescer 4 and entered by journey, backwash water through backwashing pump, counter-flushing pipeline
Alternately backwash, the sewage containing sand after backwash are sent by backwash water blowoff line to cesspool.
General export in the main entrance of process to process is equipped with maintenance or accident bypass line.It, can by 2 grades of solid-liquor separations
The solid particle and the miscellaneous content of machine and partial size of sewage is effectively reduced, substantially extends the service life of water injecting pump vulnerable part.
Detailed description of the invention
Below with reference to embodiment, the utility model is described in further detail:
Fig. 1 is the utility model embodiment process flow.
