Description of the drawings
Below in conjunction with accompanying drawings and embodiments, the invention will be further described, in attached drawing:
Fig. 1 is the stereoscopic schematic diagram of the three-dimensional visualization teaching mode of polymorphic type trap and the oil-gas reservoir of the present invention;
Fig. 2 is the schematic diagram changed in A-A ' sections about the reservoir thickness being sandwiched between top, bottom surface in Fig. 1;
Fig. 3 is the vertical view of three-dimensional visualization teaching mode in Fig. 1.
Specific embodiment
For a clearer understanding of the technical characteristics, objects and effects of the present invention, now control attached drawing is described in detail The specific embodiment of the present invention.
With reference to figure 1, Fig. 2 and Fig. 3, wherein Fig. 1 is the three-dimensional visualization religion of polymorphic type trap and the oil-gas reservoir of the present invention The stereoscopic schematic diagram of model is learned, Fig. 2 is the schematic diagram changed in A-A ' sections about reservoir thickness in Fig. 1, and Fig. 3 is three in Fig. 1 The contour of top surface has been marked out in the vertical view of dimension Visual Teaching model, wherein Fig. 1 and Fig. 3.The three-dimensional visualization is imparted knowledge to students Model has wedge-shaped container made of transparent glass, and wedge-shaped container is the wedge being made of 5 faces, according to top, bottom surface The reservoir formation feature machining of typical types trap into curved surface, plane of the forward and backward side for nearly wedge shape, the end that has a down dip is near wide Plane;Container updip end is then pushed up, bottom overlapping.Pedestal 9 supports made of transparent support plate, and pedestal 9 is also preferably transparent Glass is made.
Filled with transparent granular filler --- bead in wedge-shaped container, underground is simulated by transparent glass pearl and is stored up Collect formation debris structure and pore system, student can watch oil, distribution and change of the gas and water inside wedge-shaped container during teaching The characteristics of changing, understanding oil-gas reservoir and forming process.The top of wedge-shaped container, the form of bottom surface rise and fall, are bent in the same direction, including multiple grand It rises and forms multiple anticlinal traps or oil-gas reservoir, the inside of these protuberances is connected;Further include a fault trap or oil-gas reservoir.Wedge It describes and oil inlet 5, air inlet 6, intake-outlet 7 and intake-outlet 8 is also respectively provided on device.Oil inlet 5, air inlet 6 and Intake-outlet 7 is respectively positioned on the end that has a down dip of the wedge-shaped container residing for Fig. 1 lower left corners of wedge-shaped container, and is preferably located in place side And/or on bottom surface;The updip end of the wedge-shaped container residing for Fig. 1 upper right corner where intake-outlet 8, and it is preferably provided at updip Hold top surface.The connection that is locally staggered between two parts at one of position of wedge-shaped container forms fault block type trap 1, mark 4 As fault structure specifically can refer to left-hand component in Fig. 2;Wedge-shaped container is by the difference in height between upper surface, bottom surface come body Existing Reservoir Thickness variation, wedge-shaped container, in reduction trend, form a flat tip, so as to simulate to updip end thickness Go out up dip pinchout depositional trap 3, specifically refer to the region on the right in Fig. 2;Plurality of protuberance forms serial anticline type trap 2.It is also useful for being put into or pouring out the opening of above-mentioned granular filler on wedge-shaped container, size therewith is provided in the opening The corresponding baffle 10 being detachably connected, can block opening by baffle 10, prevent granular filler from leaking out, baffle 10 can It is fixed on wedge-shaped container by screw, when needing to be put into or pour out above-mentioned granular filler, disassembles baffle 10.It is also communicated with safety valve on wedge-shaped container, when the air in wedge-shaped container is too many, can be discharged from safety valve.
In use, opening the safety-valve, water is filled into container, simulation reservoir pore system from intake-outlet 7 or intake-outlet 8 It is full of oil-reservoir water in system;Again light liquid (such as edible oil, condensate) Simulation of Crude Oil of density ratio water is injected from oil inlet 5;From Air inlet 6 injects air simulation natural gas.Oil, air enter in wedge-shaped container, are flowed between bead under the buoyancy of water It is dynamic, when the amount of injection is enough, the oil-gas reservoir of fault block type, the formation anticline type oil at anticline type trap 2 are formed in fault block type trap 1 Gas reservoir forms up dip pinchout lithologic deposit at up dip pinchout depositional trap 3.There are spill points for each trap, represent Trap maximum stores up oil/gas ability.In above process, outlet and oily migration, accumulation process can be simulated and pass through spill point Spilling.
Stop injecting gas, oil and after standing a period of time into wedge-shaped container, can be observed in each trap/oil-gas reservoir Gas-oil-water three-phase fluid presses the distribution relation of gravitational differentiation.While maintaining to inject water at intake-outlet 8, from Inlet and outlet water Under conditions of mouth 7 discharges superfluous waters, gas water interface or oil/water in oil-gas anticlinal deposits occur to tilt to water outlet, that is, simulate Form the transformation of oil-gas reservoir, the forming process of hydro-dynamic reservoirs.
It should be understood that it is above-mentioned first fill water after, can be fed only with gas, oil in one or two kinds of, shape Into pure gas reservoir, pure oil reservoir or oil-gas reservoir.
The remarkable advantage of the present invention:1) available for anticlinal trap, fault trap, up dip pinchout depositional trap, hydrodynamic force circle Object colour terms observation, the description of 4 big type CHARACTERISTICS OF TRAPs such as close, the spill point of trap, closed area are with being closed the parameters such as height Observation in kind;2) observation in kind, the description available for Oil-gas Accumulation Types and feature, the oily gas column height of oil-gas reservoir, pneumatic jack with The intuitive observation measurement of the parameters such as oil ring;3) it is full of oil in the porous formation of water, the migration of gas and Aggregation indica for simulating Process;And reconstruction of oil and gas pools, hydro-dynamic reservoirs forming process etc..
The embodiment of the present invention is described above in conjunction with attached drawing, but the invention is not limited in above-mentioned specific Embodiment, above-mentioned specific embodiment are only schematical rather than restricted.Those of ordinary skill in the art Under the enlightenment of the present invention, present inventive concept and scope of the claimed protection are not being departed from, can also made very much Form, these are belonged within the protection of the present invention.
