Description
Technical field
The present invention relates to a kind of well cementation fluid-monitoring system, particularly a kind of reinforcing oil well mud flow meter.
Background technology
For a long time, well cementation fluid-monitoring system can not meet the demand at scene, the replacement during particularly replacing always
Flow quantity and volume monitoring, using drilling fluid displacing effusion meter always, but the most do not solving stability and accuracy
Problem, always effusion meter, measuring tank, pump rush tripartite's metering, finally measure with the craft of measuring tank and are as the criterion.
Several well cementation effusion meter pluses and minuses that existing document is introduced are as follows:
1, radioactive density meter, measures parameter single (being only capable of measuring density), and measurement result is relevant with physical property and composition, warp
Often needing to demarcate, precision is the highest；There is radioactive source, have in management and use many not enough.
2, turbine flowmeter, flow accuracy can meet requirement substantially, but turbine is often by the foreign material blocking in cement mortar, impact
Construction, and rinse higher with bearing maintenance requirement, the life-span is short.
3, electromagnetic flowmeter and ultrasonic flowmeter etc. are all very big with physical property and composition relation, are difficult to popularization at well cementation scene and make
With.
4, during manual measurement density, the original backwardness of working method, speed is slow, discontinuous, poor real, precision are low, subjective
Property is big.
The effusion meter used at present, can only measure flow, it is impossible to measure fluid density.
Along with the oil well of complex geological condition gets more and more, site operation hole condition becomes increasingly complex, and is badly in need of solving well cementation stream
The accuracy of body monitoring and the stability of instrumentation, in addition it is also necessary to measure the parameters such as density, pressure, temperature simultaneously.
Along with science and technology and the development of information technology and technological progress, move towards as early as possible in the urgent need to casing and cementing information-based and from
Dynamicization, this accuracy and the stability of instrumentation being also badly in need of solving well cementation fluid inspection, it is also desirable to simultaneously measure density, pressure
The parameter such as power, temperature.
Well cementation the succeeding in developing of fluid-monitoring system, also provides for the fine controlled pressure drilling of drilling engineering, overflow monitoring etc.
New reference and reference.
In recent years, external cementing truck has been equipped with Coriolis mass meter, is used for directly measuring cement slurry density and flow
(Non-nuclear Coriolis mass flow meter；Coriolis meters for mass density and
flow measurement).Domestic cementing truck Density Automatic Control System, it is (close that great majority are also equipped with non-radioactive source density meter
Degree sensor and densimeter transmitter), but mainly density sensor is arranged on (low pressure, float on slurry secondary cycle pipeline
The vibration of amount, no pulse), it is used for measuring density rather than for measuring flow.
Before 20 years, Xi'an shiyou University just with several unit joint studies based on the " cement mortar that Coriolis force is theoretical
Density flow automatic measurement system " (patent name in 1993: slurry parameter auto-testing device in use for oil and/or gas field well drilling and cementing, patent
Number: CN93104893.1,2 papers in 1996,1997), paper is tried out in 3 oil fields.But owing to price is held high
Expensive (only sensor is with regard to more than 100,000 yuan), currently without the record or the report that find popularization and application.
Xi'an shiyou University just with effusion meter and the densimeter of several unit joint studies, the sensor of use uses
Micro Motion standard DH type mass flow sensor (being a kind of U-shaped tubular structure), can gather density and flow two simultaneously
Individual parameter.Its shatter-proof, wear-resisting, high pressure resistant (up to 27.6MPa) is said according to data；Precision high (being better than 0.4%), flow are big, work
Temperature range width；Can measure continuously, measurement result is unrelated with medium physical property and composition；Pipeline, without any restricting element, does not affects
Media flow state, crushing is little, it is simple to rinse, will not blocking；Installing sensor and need not straight length, engaged position is little；Use
Life-span is long, it is not necessary to maintenance etc., it is ensured that reliability and performance indications meet requirement.
At present, the research of domestic coriolis flowmeter manufactures existing preferably development, and its price is also decreased obviously.
But the effusion meter produced at present can't fully meet the actual demand at scene.It is mainly manifested in following several side
Face:
1, resistance to force down
At present the rated operating pressure of mass flowmenter is 4MPa, can apply at the flow of well head outlet and close after transformation
Degree is measured, but on-the-spot need to develop be minimum rated operating pressure be effusion meter and the densimeter of 35MPa.
2, frequency of vibration is overlapping
The ultimate principle of coriolis flowmeter be measure bend pipe frequency of vibration to obtain data, current frequency of vibration is
80-90Hz, and the pulse frequency of the pump of site operation is 20-60Hz, bigger on accuracy of data acquisition impact.
Manufacturer does part test with current coriolis flowmeter and measures, and uses CMF050 biosensor assay, vibration
Affect experiment instrument Watch Error to fluctuate in 1%-6% scope；CMF080 biosensor assay, vibration effect experiment instrument Watch Error is used to exist
Fluctuate within 1%.Estimate taking some anti-vibration measures (such as support) that can apply at the scene, shaking of CMF080 sensor
Within dynamic impact can be controlled in 0.5%.Accordingly, it would be desirable to carry out Vibration Absorption Designing or filter design.
3, volume is bigger
The turbine flowmeter volume of onsite application is little at present, carries easy for installation.And the body of current coriolis flowmeter
Long-pending relatively big, the three-dimensional dimension of CMF080 is 450 × 1250 × 1600mm, weight about 400kg.Consideration is needed to reduce volume, reduction
Weight, the problem such as it is easily attached.
4, price is higher, is not a class with turbine flowmeter and electromagnetic flowmeter.
