Description
Technical field
The utility model relates to Measuring Technique for Water Content of Crude field, in particular to one kind of gathering station external transport pipeline is non-to be connect
Touch densimetry crude oil water content measuring device.
Background technique
Important parameter of the crude oil water content as oil exploitation and petrochemical industry, accurate measurement are related to adopting for crude oil
Out, it is dehydrated, collects defeated, metering, trade, refinery etc..In oilfield production, crude oil water content is to the estimation of original yield, out oil level
Set, the prediction in oil development service life, automation of recovering the oil management etc. have great importance；In the daily receipts fry dried food ingredients of oil depot
During oily production operation, gas station sell oil plant, the moisture content of oil product in real time, accurately measure, then is to ensure
Oil product exchange receives the key of accuracy.Therefore the production sum aggregate of crude oil it is defeated, it is outer it is defeated during must all measure crude oil
Moisture content.
Currently, there are mainly two types of modes for the measurement of crude oil water content: manual measurement and on-line measurement.It is general to take manually
The mode of the static measurement of sampling and conversion of tabling look-up is because its inefficiency, manual operation factor are affected and actual effect difference etc.
Reason can no longer meet the needs of Modern oil field crude oil production Trade Measures.On-line measurement crude oil water content mainly uses base
In the crude oil aqueous tester online of different principle.In present China market online aqueous tester due to price it is very high
It is expensive, and exist and be not suitable for the factors such as the environment of the oilfield surface engineering condition of production, furthermore the country does not grasp its important technology,
So that operational management and dimension interworking is generated considerable inconvenience, thus only has a small amount of unit now and still using.So research one
The crude oil water content in-situ measurement equipment of kind suitable defeated processing metering of crude oil production collection is particularly significant to want and be badly in need of.
Summary of the invention
For the defects of the degree of automation of the existing technology is low, service life is short, the purpose of this utility model is to mention
For a kind of contactless densimetry crude oil water content measuring device, on-line measurement is realized to crude oil water content based on densimetry, is mentioned
Package unit service life including high instrument and meter, avoids the measurement error due to caused by environment and human factor, convenient for tearing open
Unload cleaning, application easy to spread.
In order to achieve the above object, the technical solution of the utility model are as follows:
A kind of contactless densimetry crude oil water content measuring device, including fluid reservoir 1, fluid reservoir 1 is by inside and outside two phases
Logical tank body is integrated by the nestable installation of ring flange 2, and pressure-temperature sensor is respectively set in three positions of upper, middle and lower of inner canister
3, outer pot bottom passes sequentially through filtering buffer unit 5, third motor-driven valve 6, centrifugal pump 4, the first motor-driven valve 8 and is connected to oil inlet；
Outer tank bottom sides are connected to oil outlet by the second motor-driven valve 11；Outer tank bottom sides and interior pot bottom pass through the 5th motor-driven valve
7, centrifugal pump 4, the 4th motor-driven valve 9 are connected to oil outlet.
Hand-operated valve 10 is provided on the pipeline of centrifugal pump 4 to oil outlet.
The utility model has the advantages that:
1, the utility model is different from sensor in the prior art and is placed in oil discharge outlet contact crude oil for a long time, but will sensing
Device 3 is placed in inner canister, and only measurement Shi Caiyu crude oil directly contacts, and improves the service life of sensor, improves measurement accuracy.
2, the inside and outside tank body of the utility model is integrated by the nestable installation of ring flange 2, cleaning easy to disassemble.
3, the utility model gets rid of the shortcomings that traditional communication type measurement requires the height of measuring device, can be any
Height installation does not affect its measurement.
4, mix a large amount of moisture and other impurities in the middle and later periods of oilfield exploitation, crude oil, and the water content of crude oil
Directly affect the quality of crude oil and the cost of exploitation, if can in advance accurately measurement exploitation when crude oil in water content, in time
Control measure are taken, then high efficiency may be implemented, reduce cost exploitation.Since the environment and condition in oil field are relative complex severe,
It it requires that measuring device is simple, stable, reliable, easy to maintain, easy to spread.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the working principle flow chart of the utility model.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawing.
Referring to Fig.1, a kind of contactless densimetry crude oil water content measuring device, including fluid reservoir 1, fluid reservoir 1 by it is interior,
Outer two tank bodies communicated are integrated by the nestable installation of ring flange 2, and pressure temperature is respectively set in three positions of upper, middle and lower of inner canister
Sensor 3 is spent, outer pot bottom passes sequentially through filtering buffer unit 5, third motor-driven valve 6, centrifugal pump 4, the first motor-driven valve 8 and oil inlet
