Description
Technical field
The present invention relates in particular to a kind of electric analog system and method for complex structural well percolation law about oil-gas reservoir seepage flow technology.
Background technology
The water power simulated experiment is a kind of analogue experiment installation of developing according to the water power principle of similitude.The research that it is applied to the petrol-gas permeation fluid mechanics problem the earliest is 1933, and nineteen thirties, numerical simulation technology did not also grow up to the fifties, and research oil-gas reservoir Seepage problems mainly adopts mathematical method and physical simulating method.Because water power simulated experiment instrument is simple in structure, easy to operate, low price, and can react the underground fluid percolation law intuitively, therefore, that used at that time is very extensive.Because the appearance of computer and developing rapidly, the method for numerical simulation fast development was got up afterwards, and it is fewer and feweri that electrical simulation experiment is carried out.In recent years; Horizontal well has appearred, Multilateral Wells, multihole well; Complex structural wells such as fish bony spur well; And multiple tertiary oil recovery technology, the technology that these are new and the seepage flow mechanism of method are very complicated, only rely on the method for mathematical analysis and the very difficult percolation law of describing underground fluid exactly of method of numerical simulation.In addition, the result of study of Seepage problems such as present existing complex structural well also all is to have obtained after the simplification to a certain degree in that formation condition has been carried out, and has certain deviation with actual percolation law, even bigger with the actual conditions deviation.Therefore, the water power simulated experiment receives people's attention again.Adopt the water power simulated experiment can simulate the fringe conditions of various complicated wells at an easy rate, can directly observe the mobility status of fluid, and be easy to test oil well output (injection rate), isobar distribution etc.Experimental result can also be used to checking the accuracy of numerical simulation and analytic solutions.Therefore, the developed once more and utilization of water power simulated experiment.
Utilize the rule of electric field simulation formation fluid steady seepage, mechanism is the water power theory of similarity: the differential equation that incompressible underground fluid flows through porous media and electric charge are through having similitude between the mobile differential equation of conductor material.
Underground fluid meets Darcy's law and Laplace's equation through the steady seepage of porous media:
Electric current flowing in conducting medium reaches Potential Distributing and meets Ohm's law and Laplace's equation:
According to the theory of similarity, the shape of seepage field and electric field is similar with distribution, and both can obtain similar separating under similar fringe conditions.Flow in electric current in the electric field, voltage and distribution thereof and the steady seepage field, pressure and distribution thereof have following corresponding proportionate relationship.
1) geometric similarity coefficient
The ratio of model geometric parameter and the corresponding geometric parameter of oil reservoir is the geometric similarity coefficient.The geometric similarity coefficient of arbitrfary point must be identical.
2) pressure similarity factor
The ratio of the pressure reduction in potential difference in the model between 2 and the stratum between two respective point.
3) resistance similarity factor
4) mobile similarity factor
5) flow similarity factor
6) similarity criterion is derived
In flow unit, Ohm's law and Darcy's law are rewritten as respectively:
Simultaneous (3)-(9) formula gets:
In the formula, be designated as m under the model data, be designated as r under the formation data.
L---physical dimension
ρ---electrical conductivity of solution
K---permeability
μ---viscosity of crude
I---electric current
Q---well production (or injection rate)
(R)
m---the resistance of electrolyte solution
(R
f)
r---the filtrational resistance of formation fluid
Δ U---potential difference
Δ P---pressure differential
The similarity criterion that formula (11) must satisfy for model wherein has two parameters freely to confirm, the 3rd parameter must be derived by similarity criterion.Because electric current can reach stable moment, thereby the electrical analogue process in this experiment is the single-phase steady seepage process of actual formation.
