Abstract
The utility model discloses a model enabling real-time observation of oil displacement from a core. The model comprises a transparent cuboid model body; a rectangular groove is arranged in the center of the model body and serves as a sample bin; the upper surface of the sample bin is covered by a transparent plate matched with a bin opening so that an observation window is formed; the centers of the front lateral surface and the back lateral surface of the sample bin are respectively provided with a duct A perpendicular to the lateral surfaces; the center of the left lateral surface or the right lateral surface of the sample bin is provided with a duct B perpendicular to the lateral surface; and the sample bin is a sealed bin after the ducts A and the duct B are sealed. The sample bin of the model is arranged into the sealed bin, and the real pressure of a stratum can be realized in the sample bin after pressurization through the duct B and an annular pressure pump, so that the problem that a crude oil displacement model cannot simulate stratum pressure is solved. In addition, corresponding liquid is guided into the sample bin through the ducts, real core wettability can be kept, and a forceful experimental model is provided for further research of a reservoir stratum hole structure and observation of crude oil displacement.
Description
Technical field
The utility model relates to a kind of in oil field development is produced, the experimental model that the different lithology displacement process is observed.
Background technology
Pore structure of reservoir is the key factor that influences reservoir seepage flow feature, also is the important internal cause that influences the waterflooding oil field recovery ratio.In order to study the influence of RESERVOIR PORE STRUCTURE to waterflooding development effect, past is adopted the test of microcosmic water drive oil always, by the observation of glass etching model having been studied the influence of heterogeneity of pore structure to the reservoir remaining oil distribution, some Preliminary study have been obtained, but, make research be subjected to limitation owing to can not keep real rock wettability, true reservoir pore space network structure, real bottom pressure.
Summary of the invention
The purpose of this utility model is at the problem that exists in the background technology, a kind of model that can carry out Real Time Observation to the rock core oil displacement process is provided, this model can keep real rock wettability, embodies real reservoir pore space network structure, and can bottom pressure that is virtually reality like reality.
For achieving the above object, the technical scheme that the application adopts is: but the model of the Real Time Observation rock core displacement of reservoir oil, comprise a see-through model body, model ontology be shaped as cuboid, the center of this model ontology offers rectangular recess, this groove shaped becomes sample bin, and the upper surface of sample bin is stamped the transparent panel that matches with Hatch Opening, forms observation port; In the heart, offer the A duct perpendicular to its side respectively in former and later two sides of sample bin, in the heart, offer the B duct perpendicular to its side in the left side of sample bin or right flank, sample bin is a gas-tight silo behind shutoff A duct and the B duct.
Beneficial effect: but the model of the application's the Real Time Observation rock core displacement of reservoir oil, sample bin is set to gas-tight silo, after B duct and the pressurization of ring press pump, can reach the stratum true pressure in the sample bin, realize the purpose of simulated formation pressure, the sample bin passing hole channel imports corresponding liquid in addition, can keep real core wettability, for further research RESERVOIR PORE STRUCTURE, observation mother oil displacement provide strong experimental model.
Description of drawings
But Fig. 1 is the structure of models schematic diagram of the utility model Real Time Observation rock core displacement of reservoir oil.
Among the figure: model ontology-1, sample bin-2, A duct-3, B duct-4.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
By shown in Figure 1, but the model of the Real Time Observation rock core displacement of reservoir oil, comprise a see-through model body 1, model ontology 1 be shaped as cuboid, the center of this model ontology 1 offers rectangular recess, this groove shaped becomes sample bin 2, and the upper surface of sample bin 2 is stamped the transparent panel that matches with Hatch Opening, forms observation port; In the heart, offer the A duct 3 perpendicular to its side respectively in former and later two sides of sample bin 2, in the heart, offer the B duct 4 perpendicular to its side in the left side of sample bin 2 or right flank, sample bin 2 is a gas-tight silo behind shutoff A duct and the B duct.
During use, adopt the anticorrosion optical thin film of resistance to compression that the core sample of handling is encapsulated, be fixed in the resistance to compression sample bin of band observation port, two A ducts 3 are respectively going into, exporting of liquid, and utilizing the ring press pump to be connected with the B duct, 2 pressurizations reach the stratum true pressure to sample bin.
Utilize this model, can the Real Time Observation mother oil displacement process, the distribution situation of residual oil in the hole, and can carry out sensitiveness to sample and handle the response situation of home position observation sample.
