Description
Technical field
The present invention relates to a kind of profit containing method for measuring and calculating.
Background technology
Existing Chinese patent ZL201020145790.X discloses a kind of oil field oil storage tank intelligence
Measurement monitoring system, this system utilizes the data of liquid level sensor real-time Transmission to coordinate oil storage tank
Physical dimension calculates the volume of oil water mixture in oil storage tank, utilizes pressure transducer to obtain
Data coordinate the physical dimension of oil storage tank to calculate the quality of oil water mixture in oil storage tank, and root
Calculate oil-water ratio according to water, oil two media density difference, obtain oil pump capacity and water according to oil-water ratio
Amount.Profit cubage method disclosed in this patent, needs first to sense liquid level before the computation
Device and pressure transducer carry out the Accurate Calibration of initial position, and especially pressure transducer is located at storage
The bottom surface of oil tank, during actual installation, tank elevation is usually 2.5 meters or 3.9 meters,
And it is all the oil tank of normal production and application, uses environment relatively more severe, be difficult to accurately be directed at pressure
The initial position of strong sensor, has large effect to follow-up computational accuracy.
Summary of the invention
It is an object of the invention to provide a kind of profit and contain method for measuring and calculating, to solve in existing method
Accurate Calibration pressure transducer initial position be difficult to problem of implementation.
For achieving the above object, the profit of present invention technical scheme Han method for measuring and calculating is as follows: row
Before liquid, obtain total liquid level h of oil mixing with water liquid in oil tank, arrange below tank shell
Drainage pipe distance tank bottom height H；During discharge opeing, by the oil accessed in Drainage pipe
When water finder monitoring starts oil extraction, and when recording beginning oil extraction, in oil tank, liquid level is high simultaneously
Degree h1, according to formula cwater=(h-h1+H)/h is calculated moisture content.
In oil tank, the acquisition of liquid level is obtained by liquid level sensor.
Drainage pipe be located at below tank shell refer to below the bottom surface of tank shell or side close
The position of bottom surface, H=0 when Drainage pipe is located at the bottom surface of tank shell.
When Drainage pipe is located at the position of close bottom surface below tank shell side, oil before discharge opeing
In tank, the liquid level of the water in oil mixing with water liquid is higher than the height of Drainage pipe.
The profit of the present invention contains method for measuring and calculating, accesses profit in the Drainage pipe below oil tank
Detector, utilizes profit density different, and first discharge is water, and rear discharge is oil, utilizes oil
Water finder monitors when draining, when oil extraction, the simultaneously change of detection oil innage,
It is calculated the size of moisture content in oil mixing with water liquid；It is high that this method has only to detect liquid level
Degree, it is to avoid need two kinds of sensor essences during by pressure height hybrid measurement measuring and calculating oil-water ratio
Close check and correction, the requirement of strict conformance, greatly reduce sensor design difficulty, profit detector
Installing simple, computational methods are simple and easy to do, and degree of accuracy is high.
Detailed description of the invention
In order to measure the moisture content of oil mixing with water liquid in a specific volume, can be under oil tank
Accessing profit detector in the Drainage pipe of side, utilize profit density different, first discharge is water,
Heel row is fuel-displaced, utilizes profit detector to differentiate when draining, when oil extraction, detects tank simultaneously
Interior liquid level changes, thus calculates moisture content size.Specific volume can be existing storage
Oil tank, it is also possible to be specific measurement oil tank；In oil tank, the acquisition of liquid level is to pass through liquid
Level sensor obtains, and liquid level sensor can be ultrasonic liquid level sensor, it is also possible to be pressure
Power liquid level sensor, or the liquid level sensor of other form any；Drainage pipe is located at oil tank
Refer to the position near bottom surface below the bottom surface of tank shell or side below housing, work as discharging tube
Road is located at below tank shell side when the position of bottom surface, oil mixing with water in oil tank before discharge opeing
The liquid level of the water in liquid is higher than the height of Drainage pipe, when in mixed liquor, the ratio of water is very
Time low, the height H of leakage fluid dram should be reduced so that H drops to reality to the impact of water content as far as possible
Negligible degree in using.
Concrete profit containing method for measuring and calculating is: before discharge opeing, obtains oil mixing with water liquid in oil tank
Total liquid level h, below tank shell arrange Drainage pipe distance tank bottom height H；
During discharge opeing, when start oil extraction by the profit detector monitors accessed in Drainage pipe, and same
Time record beginning oil extraction time oil tank in liquid level h1, according to formula cwater=(h-h1+H)/h
It is calculated moisture content.
This method is while detection profit detector, it is only necessary to install the liquid measuring liquid level
Level sensor is the most permissible, greatly reduces the required precision installing sensing station, and profit detects
Device is installed simple, and computational methods are simple and easy to do, and degree of accuracy is high.
It should be noted last that: above example is only by the skill illustrating and not to limit the present invention
Art scheme, although the present invention being described in detail with reference to above-described embodiment, this area general
Lead to and skilled artisan understands that；Still the present invention can be modified or equivalent, and
Without departing from any modification or partial replacement of the spirit and scope of the present invention, it all should be contained at this
In the middle of the right of invention.
