Description
Technical field
A kind of apparatus and method of comprehensive NMR and CT scan measurement oil gas minimum miscibility pressure, belong to petroleum works technology
Field.
Background technique
Minimum miscibility pressure is that the miscible minimum pressure as single-phase of oil gas two, accurate quick are surveyed at a certain temperature
The minimum miscibility pressure for measuring oil gas, for gas injection (CO2, lighter hydrocarbons etc.) improve oil recovery factor, the assessment of mixed phase immiscible displacement, adopt
The economic design of oil and the engineering researcies such as greenhouse gases effectively are buried with great importance.It can be with by gas drive technology
Oil recovery 10%-15% is further increased on the basis of routine techniques, therefore the further gas-liquid of further investigation oil gas
Biphase equilibrium rule is lightweight and CO2The underground multi-phase multi-component migration rule analysis of tertiary oil recovery provides Basic Physical Properties Data
It is necessary to.
The experimental measurement method of minimum miscibility pressure mainly includes tubule method, rises and steep instrument method, interfacial tension disappearance method etc..Carefully
Tube method is to apply earliest and in engineering most Experimental Determination Methods, and this method has developed into the standard method in engineering, but
It is its measurement process complexity, time-consuming, and it is less economical, and for the judgment criteria disunity of mixed phase；Rise bubble instrument subtraction unit it is simple,
Good economy performance, and it is faster, but non-quantized criterion of this method using the change of bubble shape as oil gas minimum miscibility pressure,
Error is larger, lacks quantitative information, there is certain subjectivity on the downtown streets of mixed phase, so that experimental result has uncertainty；
In recent years the interfacial tension disappearance method that new development is got up passes through measurement oil using the feature that interfacial tension disappearance is zero when oil gas mixed phase
The interfacial tension of gas judges minimum miscibility pressure point with pressure history, and this method only focuses on interfacial tension, and this is single
Physical quantity, and the inspection of a large amount of standard complexity gas-liquid systems is needed, there are still certain limitations.
Nineteen eighty-three Stalkup proposes slim-tube test method, is to generally acknowledge general measurement minimum miscibility pressure both at home and abroad at present
Standard method and engineering in apply most Experimental Determination Methods, this method has developed into the standard method in engineering, but
It is its measurement process complexity, time-consuming, and it is less economical, and for the judgment criteria disunity of mixed phase；1986,
Christiansen proposes a kind of method-liter bubble instrument method (RBA) of new measurement oil gas minimum miscibility pressure, this method energy
It quickly carries out oil gas THE MINIMUM MISCIBLE PRESSURE and experiment spends less and more quicker than slim-tube test method, economy；But simultaneously
Also have certain limitation, there is the subjective factor judged for bubble shape influences in measurement process, and lack for
The quantitative analysis information of the changing rule of oil-gas component, interfacial tension and displacement efficiency etc..Harmon in 1988 and Grigg are proposed
Vapour density method, this method use dynamic test, directly the density-pressure relationship of measurement injection rich gas phase, with gas with it is oily
Dissolution characteristics both determine mixed phase oil gas minimum miscibility pressure.The disadvantage is that the repeatability of measurement miscible pressure is not strong, lack
Weary standard test process and mixed phase standard, and application range is narrow, only uses in some a small ranges.The foreign countries such as Rao in 1998
Researcher proposes that disappearance method in interface measures minimum miscibility pressure, which possesses that quick, easy (one minimum of measurement is mixed
Phase pressure needs 4-6 hours), but this method requires measure of precision high laboratory apparatus, cannot be widely used.
