Description
Technical field
The utility model relates to the experimental provision of Gas Accumulation, specifically, relate to the physical simulating device of a kind of sand body-unconformity surface-fault transfer system control oil migration, by changing the configuration relation of sand body-unconformity surface-tomography, thus spike sand body-unconformity surface-fault controlling oil dust trajectory and migration process.
Background technology
Oil gas after primary migration row hydrocarbon, in the process before entering trap, enters trap through secondary migration from source rock in migration pathway.These main migration pathways comprise the composite type of carrier bed (sand body is oozed in high hole), unconformity surface, tomography and this 3 type.
Sand body be basin oil-gas migration be substantially the most also most important a kind of migration pathway.Sand body is also a natural body being worth research, and in the section containing impermeability shale, sand body is the infiltration lane (the Pei Di village, 1977) of underground water and oil gas.Study the distribution of sand body in great detail, extend and Morphological Features, to determining that there is meaning of the utmost importance (the precious Jun of Liu etc., 1985) in favourable oil storage area.Sand body is just defined as a sand body that continuous print can chart separately by the Pei Di village (1977).Sand body is defined as the summation of settling sand petrofacies by " CNPC's geology will " (rolling up two times), belongs to a part for sedimentary system.Tian Zhaocheng etc. (2002) then think that sand body is the space configuration occupied by gravel deposit, and it is the concentrated expression of sedimentary environment, deposition space, sedimentary particle, are parts for sedimentary system.By form sand body can be divided into seat shape, (fan-shaped) of wedge-like, banded and complicated bifurcated (He Qixiang, 1978); Fluvial sandbody, delta sandbody, river estuary sand body, seashore sand body, barrier island sand body, continental shelf sand body, lake sand body etc. (the precious Jun of Liu etc., 1985) can be divided into by genetic sandstones.
Unconformability is the inharmonic contact relation of one that the lost strata remained in stratum presents, and represent zonal interruption in deposition and degrade event, is product (Adams, 1954 of tectonic movement and eustasy; Cheng Hui etc., 1998).Nineteen eighty-three, Pan Zhongxiang discusses the importance of unconformability to hydrocarbon migration and accumulation.Cai Chunfang etc., He Dengfa, Liu Xiaohan equal nineteen ninety-five and have studied the effect of unconformability in Tarim Basin and Shan-Gan-Ning Basin Hydrocarbon Formation Reservoirs.Fu Guang etc. (1995) think that the existence of unconformity surface can improve reservoir space and the performance of oil gas.When unconformity surface is formed, karstification has constructive transformation effect to the reservoir under unconformity surface, the secondary reservoir transformed, and corrosion hole, hole, seam are grown, and are favourable places (Ai Huaguo etc., 1996 of oil-gas accumulation; Wu second place etc., 1996).Unconformable existence can provide the hydrocarbon trap (Lv Xiuxiang, 1997) of buried hill type, strata denudation type and stratigraphic overlap type 3 type.Simultaneously because the distribution of unconformity surface has the feature of regionality, stability, it can form the poly-passage of effective fortune by the separate sand body of lateral connection, there is relative stability in the time, so it is the important channel (Chen Zhonghong etc. of oil gas long distance lateral migration, 2002,2003,2007), as (1992) researchs such as Bethke show that the oil gas in ILinois basin, North America, in western reservoir take unconformity surface as migration pathway, derive from the southernmost end in the outer basin of 100km.
Tomography, as hydrocarbon migration channel, can directly connect hydrocarbon source rock and trap.Tomography as hydrocarbon migration channel mainly by it and neighbouring network of fracture system carry out, it can make longitudinally upper hydrocarbon source rock apart from each other and trap couple together, being the bridge between hydrocarbon source rock and trap, is the important channel of oil gas long-distance migration in the vertical.As rupture in the Junggar Basin to communication oil sources and trap play vital effect, because in basin, hydrocarbon source rock depth of burial is large, in upwelling area often without hydrocarbon source rock or hydrocarbon source rock thinner, its oil gas derives from the depression of both sides mainly through oil-migrating fault, and in the neat ancient oil field that this Basin South Margin has found, airway mechanoreceptors is all grown oil-migrating fault; At this basin belly Lunan uplift, although disappearance Permian system main hydrocarbon, but because the Lu Nan fracture of the approximately EW spread in its north reaches agate lake depression, its south has east northeast and inserts in range-basin coupling to the Ji Dong fracture of spread, become oil-migrating fault, form the main thoroughfare of oil-gas migration, a large amount of oil gas is incorporated into Aggregation indica in the favourable trap in projection.Due to the channeling of tomography, result in oil gas spatially the scope of gas accumulation system and the spatial of tomography closely related, the main fortune that simultaneously faulting history also controls oil gas gathers history.
So-called hydrocarbon carrier system refers to the carrier network (Fu Guang etc., 2001) that the migration pathway connecting source rock and trap forms, and it is between source and Tibetan " bridge and tie ", is the crucial controlling factor of hydrocarbon reservoiring and distribution.The oil gas that hydrocarbon source rock generates only has just can enter trap through effective migration path system, forms hydrocarbon-bearing pool (Lin Sheqing etc., 2004).Liu Zhen etc. (2003) think migration path system relatively a certain independently oil-gas migration unit Petroleum System, are the summations of all migration pathways and relevant country rock thereof in Petroleum System.Different petroliferous basins has different migration path system, and the mode of the different oil-gas migration of migration path system is just different, and the migration of hydrocarbon-containifluids fluids can be transformed conversely and even formed new migration path system.
From the macro manifestations form forming migration path system, stratum sand body, unconformity surface and tomography are the three elements forming migration path system, they can form separately migration path system of simply migrating, and also can combine and form the migration compound trace system of relative complex.Simple migration path system comprises: 1. connected sandbody migration path system; 2. fault transfer system; 3. unconformity surface migration path system.Compound trace system comprises: the migration path system of 1. sand body-unconformity surface composition; The migration path system of 2. sand body-tomography composition; The migration path system of 3. unconformity surface-tomography composition; The migration path system of 4. sand body-unconformity surface-tomography composition.The migration path system of wherein sand body-tomography-unconformity surface composition represents one of most important type in plastid naturally.For example Hinterland of The Junggar Basin terrestrial facies protuberance Cretaceous System has found self-contained large oil and gas fields.According to the study (Chen Zhonghong etc., 2002,2003,2007), the oil of this oil gas field comes from the agate lake depression in west and the Permian system wind city group of range-basin coupling and Wu Er standing grain source rock.The oil that these source rocks generate, after discharging from source rock, first migrate in sand body delivery layer, then long-distance migration is made by the Permian system and Triassic system unconformity surface that is inner and top to Luliang Area, migration distance reaches about 20km, passes through the trap-down longitudinally again, do vertical migration after arriving Luliang Area, migrate to the Cretaceous System of shallow-layer always, form Luliang oil field.Therefore, the sand body-tomography-compound trace system of unconformity surface composition is done long-distance migration to oil gas and is meant a great.
The multi-form of migration path system plays different control actions to Oil-gas Accumulation Types, distribution.With the hydrocarbon-bearing pool that tomography is the formation of main migration pathway, because tomography has good vertical transporting capability, often can be formed at the layer position larger apart from oil-degrading bacteria space-time span, the hydrocarbon-bearing pool of multiple superposed can be formed near distributed fault.Be the hydrocarbon-bearing pool that main migration pathway is formed with connected sandbody, be often formed at apart from the nearer or adjacent layer position of oil-degrading bacteria, the distributing position of oil gas in sand body depends primarily on the nonuniformity of sand body physical property, and position Aggregation indica is oozed in be everlasting the relatively high hole of sand body of oil gas.
Central and Western China extensive development the Middle Cenozoic foreland basin with compressional structure background, Eastern China extensive development the fault depressed lacustrine basin of new generation with extension tectonic setting, no matter be these foreland basins or fault depressed lacustrine basin, there is the Geological features of oil and gas that some are similar, as having the combination of many cover storage lids, the feature of down mountainalgorithm, unconformity surface is the important channel of oil gas lateral migration, and tomography is the passage etc. of linking up bottom hydrocarbon source rock and top reservoir.Therefore, oil gas is the key factor affecting basin Hydrocarbon Formation Reservoirs along the ability of stratum sand body-unconformity surface-sand body transporting, determines oil gas Cheng Zang and the scale becoming to hide wherein.
Due to tomography, sand body, unconformity surface three is the main thoroughfare of basin oil-gas migration, tomography, sand body and unconformity surface spatially often form sand body-unconformity surface-tomography compound trace system, due to the difference of geologic function, this sand body-unconformity surface-fault transfer system can form different space distribution patterns, control migration and the gathering of oil gas, therefore three is the key factor forming hydrocarbon-bearing pool and control oil & gas pool size, research for sand body-unconformity surface-fault transfer system control oil is significant for the effect of grasp compound trace system in Hydrocarbon Formation Reservoirs and petroleum exploration and development.
The physical simulation of existing Gas Accumulation mechanism is all carry out in a large sandbox substantially, by setting up different geologic model in sandbox, simulate or verify the hydrocarbon migration and accumulation rule in certain area, not yet find that there is specially for the design of physical model of stratum sand body-unconformity surface-tomography oil-gas migration, and carry out experimental provision and the experimental technique of stratum sand body-unconformity surface-fault controlling oil study mechanism for change stratum sand body-unconformity surface-tomography configuration space mode.
Therefore, invent the experimental provision of the compound trace system of a kind of stratum sand body-unconformity surface-fault complex, may be used for inquiring into sand body-unconformity surface-fault controlling oil fate shifter mechanism, the development of oil geology subject can not only be promoted, also very meaningful to oil-gas exploration industry.
