Description
Technical field
The utility model is related to oil-field thick-oil well water mixing Auto-control of the process technology, and specifically a kind of oil well is high and low
Press water mixing automatic transfer equipment.
Background technology
Current heavy oil wells are more and more in oil field, because heavy oil wells crude oil property is sticky, flow resistance is very big, so causing
Oil well single well pipeline back pressure is too high, scene the viscosity of crude oil in pipeline is reduced using individual well water mixing so that reach reducing thick oil viscosity,
Reduce the purpose of individual well petroleum pipeline back pressure.Current water mixing mode is divided into high pressure water mixing, low pressure water mixing both of which.High pressure water mixing
From high pressure distributing room for water injection, belong to the shunting and consumption to high pressure water injection；Low pressure water mixing reclaims sewage from multi-purpose station, belongs to oil field
The dirty water reuse of extraction.Field requirement uses low pressure water mixing, only just enables high pressure when single well pipeline back pressure is too high
Water mixing de-plugging, and because heavy oil wells single well pipeline bolt blocks up the uncertainty of time, existing procedure technique can not meet high and low pressure and mix
Water changes the requirement automatically switched according to single well pipeline back pressure, and scene generally uses high pressure water mixing to heavy oil wells water mixing.
There is following defect in high pressure water mixing：One is shunting, consumption well water filling energy；Two be oil reservoir under interfering well；Three are
Conduit wiring piercing is easily caused, crude oil, sewage leakage is caused, pollutes environment.
The content of the invention
The drawbacks described above that the purpose of this utility model exists aiming at prior art, designs a kind of oil well high and low pressure and mixes
Water automatic transfer equipment.
The purpose of this utility model is realized by following technical proposals：
The utility model includes：High pressure water mixing manifold, low pressure water mixing manifold, pressure transmitter.A kind of described oil well is high,

The upper valve of low pressure, low pressure are sequentially connected in series from left to right on low pressure individual well water mixing pipeline in parallel, low pressure individual well water mixing pipeline
Watering flow auto-controlling apparatus, low pressure flow down valve；High pressure flow down valve export and low pressure flow down valve export by pipeline, elbow,
Threeway connection is together to thick oil well mouth flow, and low pressure water mixing manifold is provided with safety valve.
High pressure watering flow auto-controlling apparatus, low pressure watering flow in above-mentioned oil well high and low pressure water mixing automatic transfer equipment are certainly
Control instrument sets up RS485 communication modes, high pressure watering flow auto-controlling apparatus control high pressure watering quantity, low pressure water mixing stream with pressure transmitter
Auto-controlling apparatus control low pressure watering quantity is measured, high pressure watering flow auto-controlling apparatus, low pressure watering flow auto-controlling apparatus set interlocking on software
Program.
Operation principle：During normal low pressure water mixing, in low pressure watering flow auto-controlling apparatus setting day watering quantity, low pressure is automatically adjusted
Watering quantity, carries out Flow-rate adjustment；When pressure transmitter, which detects single well pipeline back pressure, reaches alarming value, automatic low pressure of closing is mixed
Water-carrying capacity auto-controlling apparatus, high pressure watering flow auto-controlling apparatus is automatically opened up, and in high pressure watering flow auto-controlling apparatus setting day watering quantity, works as warp
Cross high pressure water mixing and rinse unobstructed individual well petroleum pipeline, it is automatic to close high pressure watering flow automatic control when back pressure is down in zone of reasonableness
Instrument, automatically opens up low pressure watering flow auto-controlling apparatus, is automatically adjusted according to watering quantity.
The beneficial effects of the utility model are：Water-doped viscosity reduction technology is exploited suitable for oil-field thick-oil well, is realized high and low
Press water mixing pattern according to individual well petroleum pipeline back pressure to be changed to automatically switch, save water filling energy, prevent oil reservoir under interfering well, it is to avoid
Conduit wiring piercing, prevents crude oil, sewage loss, it is to avoid environmental pollution.
