Description
Technical field
The present invention relates to the experimental provisions and experimental method of oil migration and aggregation, specifically, are related to a kind of hydrodynamic force oil
Physical simulating device and experimental method are hidden, for simulating influence of the hydrodynamic force to oil reservoir.
Background technology
Formation, evolution and the oil of sedimentary basin groundwater dynamics are migrated, aggregation is very close, and hydrodynamic force is by fluid
Power and its driving mechanism dominate.In recent years many scholars have studied from different perspectives fluid dynamic, fluid driver system with
Oil is into the relation of Tibetan.Chen Heli etc. (1988,1990,1993) utilizes mudstone compacting Study of Fluid pressure, it is believed that the general distribution of oil
In residual compression lower position.Kang Yongshang etc. (1998) proposes oil into the concept of Tibetan fluid power system, and proposes that gravity drives
Ejector half, the splitting scheme that compacting is driving, fluid seals type and detention type Oil And Gas Migration And Accumulation Fluid Dynamic Systems type up for safekeeping.It is basic herein
On, Deposits Dynamics concept is emphasized, it is believed that is needed hydrokinetic research is comprehensive with other geological conditions and mechanism
Study altogether oil-gas migration process and accumulation rule (Gong Zaisheng etc., 1999；Hao Fang etc., 2000；Luo Xiaorong, 2008).It is flowing
In body dynamics research, there is viewpoint to think that the position of separation trough in formulas calculating can divide Petroleum System or Gas Accumulation list
First (Wang Zhenliang etc., 1999,2000,2002), also has and thinks that the formation of hydrodynamic force system and oil-gas reservoir is closely related, oily sinks
Product basin experience hydrogeologic cycle determine in an independent hydrodynamic force system oil gas the regularity of distribution (building chapter China etc.,
2005).Pang Xiongqi etc. (2007) thinks to embody hydrokinetic " gesture " with reflecting that " phase " of reservoir transporting capability couples, to terrestrial facies
The oil gas of garden basin has preferable control action, and it is theoretical to propose that the control of phase gesture is hidden.Chen Zhonghong etc. (2003,2010,2011,
2013) concept of Hydrodynamic field is utilized, Northwestern Margin of Junggar Basin and Hinterland Area is discussed and Bohai gulf basin Dongying is recessed
Sunken and the hydrodynamic distribution of Zhanhua depression and evolution analyze influence of the hydrodynamic force to oil-gas migration, aggregation on this basis.
The evolution of hydrocarbonaceous Hydrodynamic field and the evolution of structural evolution, underground oil and gas are closely related.With the Junggar Basin gram-hundred
Exemplified by area, which enlivens, and groundwater dynamics develop and Hydrocarbon Formation Reservoirs are more complicated.It is distributed from Hydrodynamic field,
Close to concave slope belt, for the centrifugation stream area that mudstone compacting draining is formed, fluid is mainly the hydrocarbon-containifluids fluids from source rock；
It is to ooze the centripetal stream area to be formed under atmospheric water in the onlap pinching band of pelvic floor hernia, destruction is kept to oil gas；In centre
Step-fault zone, be lower part centrifugation stream and top centripetal stream the more stream-sluicing for converging area and deep fluid is migrated upwards
Area.By taking Dongying Depression as an example, research shows that Dongying Depression (dune shape) is with typical, " youth " compacting stream basin, compacting
The centrifugation stream of stream driving is the principal element for determining oil gas lateral migration, and under centrifugation stream effect, oil gas is mainly to oil-producing conditions
Fringe area, eventually form ring (band) shape oil-gas accumulation.
By taking the Sichuan Basin as an example, Water Soluble Gas is enriched in Western Sichuan Upper Triassic Xujiahe Formation reservoir, and solution gas resource is extremely
It is few be more than the natural gas resource being enriched in gas reservoir 1~2 order of magnitude (peace Fengshan etc., 1995；Yang Keming etc., 2006).River
Western down warping region is since the late Triassic epoch, before Himalayan constructs grand liter, average 1m3It can dissolve methane 18.1m in water3.Containing
Gas saturation is 5%, under the conditions of strata pressure 90MPa, and disperse Gas content will be more than 40m3, Water Soluble Gas total amount reaches 58.1m3/
m3, it is seen that the Water Soluble Gas of hydrodynamic force driving is of great significance into Tibetan.
Hydro-dynamic reservoirs constantly have new discovery in oil-gas exploration, show weight of the hydrodynamism to Hydrocarbon Formation Reservoirs
The property wanted.The formation of hydro-dynamic reservoirs and hydrodynamic sealing process are closely related.Hydro-dynamic reservoirs are generally formed in stratum
The occurrence structural nose that slightly changes of generation and flexure band, monocline reservoir lithology be inhomogenous and thickness change band and stratum it is not whole
Near closing.At these positions, when the flowing pressure of seepage flow underground water and the buoyancy direction of oil-gas migration are opposite, are substantially equal to the magnitudes
When, it can stop and assemble oil gas, form hydro-dynamic reservoirs.
The Wei Te oil fields in Texas, USA western part Erik de Laval basin are exactly typical hydro-dynamic reservoirs.The oil field
Reservoir for Erik de Laval system stratum, be that one gentle structural nose, gradient 19m/km construct rank in the range of oil field eastwards
Ground degree is reduced to 10m/km, increases again eastwards.Reservoir updip direction is without tomography, lithologic pinch out and the mark for becoming impermeable rock stratum
As the fluviation of downdip direction forms fluid trap eastwards, and oil gas is by trap in wherein forming oil reservoir, the inclination of oil-water interfaces
It is consistent with water (flow) direction.
The Chinese patent application of Application No. 201510031808.0 discloses a kind of heterogeneous bottom-water reservoir three-dimensional article
Reason analogue experiment installation and saturation degree determine method, and device includes core holding unit, confining pressure pump, constant pressure constant speed displacement valve, piston
Formula container, oil-gas-water metering device, back pressure device, oil-gas-water metering device, insulating box, constant pressure constant speed displacement valve, pressure measurement
Device.The upper heterogeneous displacement test of progress plane and longitudinal direction is intended in the invention, edge-bottom water influences displacement and real-time analysis is oily (gas)
The researchs such as water saturation distribution.
Since hydrodynamic pool forming process is complicated, the understanding of hydrodynamic pool is only limitted to having found oil reservoir at present
The static understanding that geology is dissected and analysis is drawn, however under hydrodynamism, the process of Hydrocarbon Formation Reservoirs is a dynamic mistake
Journey, hydrodynamic flow velocity etc. has hydrodynamic pool important control action, therefore existing technology is unable to heightened awareness at present
Forming process, mechanism and its Dominated Factors of hydrodynamic pool.
Existing Gas Accumulation mechanism physical analogy is substantially to be carried out in a big sandbox, passes through the structure in sandbox
Different geological models are put, to simulate or verify some regional hydrocarbon migration and accumulation rule, still without finding to have for hydrodynamic force
The experimental provision and experimental method of hydrocarbon reservoiring process and mechanism.
