Description
Technical field
The invention belongs to petroleum exploration domains, specifically, are related to a kind of evaluation suitable for tension-shear fault closure
Method.
Background technology
Tomography is a kind of very important structural type in oil-gas bearing basin, its formation not only controls basin with evolution
Construction and evolution, and also control the formation and development of trap, directly or indirectly control hydrocarbon source rock in basin, reservoir
Development characteristics, and control the distribution of migration, aggregation and the oil-gas reservoir of oil gas.Tomography is to the control action of Hydrocarbon Formation Reservoirs, master
Show migration to oil gas, the control of accumulation process and petroleum distribution.The openability of its interrupting layer is with closure to oil gas
The destruction and reassociating of migration, aggregation and oil-gas reservoir play an important role.
The research of fault sealing property is all favored by abroad many scholars always.In the morning of fault sealing Journal of Sex Research
Stage phase is mostly the theoretical side inquired into, the closure for how predicting tomography is then concentrated mainly on now.It is studied through forefathers, it is existing
Stage altogether there are five types of fault sealing mechanism (it is pay wide etc., 2005；Zhao Mifu etc., 2005；Yang Zhi etc., 2005；Field brightness etc., 2003；It pays
It is wide etc., 1998)：1) mudstone creep is closed：This can make fracture belt generate higher breakthrough pressure；2) docking closing：Hypotonic mud page
Rock is docked with sandstone causes to block closing；3) fragmentation is closed：Due to the particulate fault gouge that fragmentation is formed, make tomography shape
At higher capillary breakthrough pressure；4) diagenesis is closed：For the small fracture belt of displacement pressure, if deuterogenesis it is cementing,
The effect for the bituminization that the diagenesis such as recrystallization and the crude oil of tomography migration occur, which will also cause to be broken, with holes oozes that small, physical property is poor
The characteristics of, oil-gas migration is prevented from this way, forms good Lateral plugging；5) layer, sheet silicate closing：It is by clast
Caused by phyllosilicate shape or sheet silicate the thin layer deformation of diagenesis, the structure of degree of closure and the silicate to deform
It is related with continuity.
Due to the importance of fault sealing Journal of Sex Research in practice, so there is a large amount of research method.Include mainly
Fault activity, fault parameter, mudstone creep, the mechanical property of tomography and the lithologic allocation of both sides, tomography clog cofficient and
Tectonic stress field etc. (Zhou Linshuai etc., 2010；Lv Yanfang etc., 2007；Zhao Mifu etc., 2006).It is upper when one disk reservoir of tomography
Direction incline when being docked with the permeable formation to disk, Fault-Sealing effect is poor.If reservoir and big set mud stone or the stronger chemical rock of plasticity
When contact, then tomography is good in the closure of this interval.The ground that can be visually seen tomography both sides can be compared by Allan graphing methods
The docking situation of layer distribution and tomography both sides sand-sand, to the more acurrate encapsulation situations for judging tomography on lateral.If
When the tendency of tomography is identical as the tendency on section both sides stratum, fault plane itself has certain openability, Fault-Sealing effect
It is poor；Conversely, the sealing ability of tomography is preferable.If tomography has been stopped action in the oil gas life residence phase, often have centainly
Vertical Sealing Properties can block oil gas in reservoir, its migration is prevented to scatter and disappear；And stopping is more long, and sealing effect is better, phase
Instead, in the oil gas life residence phase, if tomography is still movable, then closure of the tomography on vertical is often poor, therefore it can be used as channel ditch
The effective trap of logical deep source rocks and shallow-layer, oil-gas reservoir can be found in shallow-layer.The degree that closes of section (is led especially by calculating
Stress is realized) it is to be controlled by cross-section pressure；Pressure is bigger, and the degree of closing will be better, on vertical, the plugging effect of tomography
Better.The tomography transverse direction calculated according to parameters such as fault throw, depth of cover and co-hades is above and longitudinal closure is
Number Quantitative Evaluation on Fault can block fluid capacity on lateral, longitudinal direction.It is primarily adapted for use in judgement using reservoir geochemistry method
The encapsulation situations of tomography in the life residence phase, the method for use are the earth for the oil reservoir that comparative analysis is distributed near tomography both sides
Chemical parameters, this method are simple, practical；It is used by vast scientific research personnel.It is driven and is pressed using the row of interval transit time and rock
Power is inversely proportional.The replacement pressure size of purpose rock stratum is determined by the interval travel time data analyzed and researched in area's well logging, to
Can analyze determining tomography it is vertical on sealing fluid ability.It should be noted that the above overwhelming majority research method is required for
It could normal use when Stratigraphic framework is accurate.
In recent years, what fault plane applying materials analytic approach gradually became a kind of Quantitative Evaluation on Fault closure has efficacious prescriptions
Method, while being also a rational judgment mudstone creep band important parameter whether continuously distributed in fault plane.Mudstone creep is
Refer to due to fault activities, the mud stone of some plasticity is caused to be covered in the phenomenon on fault plane.Because its oozing property of hole is smaller, therefore arrange for pressure
High level is presented in power, can closed on both sides reservoir.Potentiality CSP (Clay Smear specifically can be stain by the mud stone of Bouvier (1989)
Potential)；The Shale smear factor SSF (Shale Smear Factor) and Yielding that lindsay etc. (1993) is proposed
Quantitative assessment is carried out Deng the fault gouge ratio SGR (Shale Gouge Ratio) of (1997) proposition.But it is set forth above disconnected
Mfs layer scribble effect quantitative evaluation method is inclined to the tomography slided up and down primarily directed to two disks along section, is only applicable to just break
Layer and reversed fault, and for both exist along section horizontal displacement presence along section dip slip tension-shear fault applicability compared with
Difference lacks effectively evaluating method in other words.
Therefore, how a kind of quantitative evaluation method suitable for tension-shear fault mudstone creep effect is provided, ability is become
The technical issues of field technique personnel's urgent need to resolve.
