Description
Technical field
The utility model relates to experimental provision and the experimental technique of Hydrocarbon Formation Reservoirs, specifically, relate to the physical simulating device of a kind of vertical zone of fracture mudstone creep shutoff oil gas lateral migration, by changing zone of fracture mudstone creep degree, thus spike zone of fracture controls the physical simulation of oil migration path and migration process.
Background technology
Fault sealing property refers to that match with the anisotropy of formation physical property formed can stop oil, gas of tomography continues to migrate, the new physical property making it gather together and pressure system.It spatially shows as two aspects, and one is in side direction, and tomography is to the oil, gas sealing process, the i.e. Lateral fault sealing that pass its fault surface lateral migration; Two is on vertical, and tomography is to along the oil of fault surface vertical migration, gas sealing process, i.e. fault vertical sealing ability.Fault sealing property is the key factor forming hydrocarbon-bearing pool and control oil & gas pool size, and its research has great importance in Hydrocarbon Formation Reservoirs and petroleum exploration and development for understanding tomography.
Due to the plasticity of shale layer, when breaking to form, the shale layer of fracture both sides is often pulled into zone of fracture, forms long smear layer and applies on fault surface, form impervious formation.Be squeezed into because of trap-up, due to by the Action of Gravity Field of superincumbent stratum and the effect of areal structure extrusion stress, the effect of its mudstone creep is relatively strong.The thickness of the character that the degree of zone of fracture mudstone creep and effect will be ruptured, turn-off, shale layer and the impact of the number of plies and section occurrence and form.If shale layer is thicker, the distance of smearing will be longer; The number of plies of shale layer is more, may form multiple smearing at fault surface, and the effect of smearing will be better.The occurrence of section also has influence on the growth of mudstone creep layer, and section is more slow, and its pressure be subject to is larger, and smear effect is stronger, is more conducive to the growth of smear layer.Due to the impermeability of mudstone creep layer, the mudstone creep layer that fault surface is formed can hinder the migration of oil gas.Mudstone creep also depends on its continuity distributed to the impact of fault sealing property, and the continuity of mudstone creep sheaf space distribution is again by the impact of the turn-off of tomography own, offset stratum shale layer thickness and the number of plies.Shale layer thickness is larger, and the number of plies is more, and mudstone creep layer is educated all the more, and the continuity of space distribution is better, otherwise then poorer.
The lateral seal mechanism formed by mudstone creep layer is a kind of important kind of laterally plugged fault mechanism.Mudstone creep refers to and is breaking to form in process, and the mud shale of plasticity is pulled to be applied on section into zone of fracture, forms mudstone creep layer near rupture surface.Field observation shows that in zone of fracture, mudstone creep phenomenon is very general, both can be present in trap-up, and can be present in again in trap-down.
As far back as nineteen thirty-five, Rettger observes the phenomenon that mud stone flows into zone of fracture in the experiment of soft sludge ruptural deformation; Perkins (1961) first Application mud stone flows into the phenomenon that zone of fracture mechanism removes to explain bank area, gulf, Louisiana sand sand docking fault sealing; The shale smearing that after Lindsay (1993) studies diagenesis, ruptural deformation causes, thus confirm all can form mudstone creep in the sand mud layer sequence of non-consolidation, semi-consolidated and consolidation, scale is from several millimeters that derive from thin sand-mud interbed or several centimetres, thick thick to several meters in complicated fault band; The mud that mudstone creep is defined as in tomography upper lower burrs shale layer by Sperrevik (2000) enters in the zone of fracture of growth) along fault surface distribution mud stone film; Peacock (2000) etc. thinks that the rich mud material of country rock is along fault surface distribution and smears (smear); 1997, the scholars such as Lv Yanfang and Fu Guang proposed the acquiring method of a set of applicable China tomography mud stone paint factor in conjunction with China's continental basins mature fault feature.
It is generally acknowledged, the effect of zone of fracture mudstone creep is relevant with the lithology that the mechanical property suffered by section and tomography two coil.Clausen and Gabrielsen (2002) research shows zone of fracture than forming mudstone creep greatly under tensile condition under pressure property condition, and the continuous growth trend of shale layer increases with pressure and increases.The research of mudstone creep regularity of distribution physical simulation experiment is shown that the length of zone of fracture mudstone creep layer and the thickness of offset shale layer, the proportional relation of mud stone water cut are inverse relation (Lv Yanfang etc., 2001) with turn-off.This illustrates that the thickness of shale layer is larger, and the number of plies is more, is more conducive to smearing of shale layer under pressure property environment.In order to the distribution of quantitative description fault gouge, Bouvier etc. (1989) propose the relative closure degree that can judge tomography with " mudstone creep ability " (CSP).The people such as Lindsay (1993) connect the continuity of mudstone creep layer and mudstone creep coefficient, mudstone creep coefficient (SSF) refer to fault displcement (L) with along one be inclined to fault surface in transverse section there is the ratio of the mud stone thickness (H) of obvious displacement, i.e. SSF=L/H.The method be intended to simulate with plastic manner towed enter distributed fault or inject the impact of imperviousness material of distributed fault.This method clearly supposes that in distributed fault, impermeable bed is thinning gradually.
Mudstone creep coefficient is the important parameter that the mud stone that formed near fault surface of rational judgment stains the continuous distribution with whether.By showing the research in Di Ke oil field, offshore, Trinida Colombia basin and Pu Yi oil field, in mudstone creep band, as long as SSF was no more than for 4 (being namely not less than 25% by offset ground mfs layer number percent) and just maintains space continuity, just play a part shutoff oil gas.But more domestic researchers are by pointing out the analyzing anatomical in a large amount of oil field, and effectively closing mud stone thickness (referring to preferably be not less than 25% by mud stone cumulative thickness in stratum of breaking) has fixing boundary value.But in fact effectively mudstone creep coefficient is then without unified boundary value, the main cause that in each oil field, mudstone-smearing factor close limits value is different is by fault throw with by the control of mud stone cumulative thickness in disconnected stratum.If each study area mudstone creep coefficient boundary value can be set up at work, predicting function will be played to tomography or fault block closure and degree of closure.Therefore, experimental provision and the experimental technique of inventing a kind of zone of fracture mudstone creep shutoff oil-gas migration may be used for inquiring into zone of fracture mudstone creep shutoff oil-gas migration mechanism and effective mudstone creep lower coefficient limit, the development of oil geology subject can not only be promoted, also very meaningful to oil-gas exploration industry.
The physical simulation of existing Gas Accumulation mechanism is substantially all carry out in a large sandbox, 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 the design of physical model of zone of fracture mudstone creep phenomenon, and carry out experimental provision and the experimental technique of oil control by fault study mechanism for change zone of fracture mudstone creep degree.
