As it is shown in figure 1, the determination method of this Superimposed Basins tectonodynamics evolution Feature may comprise steps of:
Step 101: choose a geologic section vertical with the fault strike of Superimposed Basins to be measured and cut open as benchmark geology
Face；
Can assume that this basin is completely covered by three dimensional seismic data for the Superimposed Basins to be measured in this example
, it is possible to intercept the seismic profile of arbitrarily trend, seismic profile is explained and can obtain corresponding geologic section.
So-called seismic profile is the section of the underground natural impedance reflecting interface of the acquisition process formation through data, in conjunction with
Drilling data, well-log information are made composite traces and can seismic profile and geological layering be combined, can be time domain also
It can be Depth Domain.So-called log sheet can be chi represents on geologic section according to a certain percentage geological phenomenon and
The map of its mutual relation, log sheet is the section of Depth Domain.
Choose geologic section move towards when, a ground vertical with the fault strike of Superimposed Basins to be measured can be chosen
Matter section is as benchmark geologic section, specifically, can substantially choose one according to regional structure direction, major faults trend
Approximately perpendicular geologic section is moved towards as benchmark geologic section, further, it is possible to use balanced cross section method with major faults
Working out the tectonic evolution sections of each main period, wherein, regional structure direction and major faults direction are the trends of approximation.
Step 102: calculate described benchmark geologic section one or more time each period interim expansion and contraction；
Wherein, expansion and contraction is the abbreviation of percentage of elongation and LVFS, and percentage of elongation can be calculated according to span, LVFS
Can be calculated according to shortening amount, usual percentage of elongation be on the occasion of, LVFS is negative value.Specifically, can be in such a way
Calculating expansion and contraction:
Assuming a length of Li of geologic section in i-th period, a length of Li+ Δ Li after deformed transformation, wherein, Δ Li is just
Being span (shortening amount), percentage of elongation (LVFS) can be expressed as Δ Li/Li.
Step 103: to meet pre-conditioned point as initial point, walk using the trend of described benchmark geologic section as benchmark
To, according to the policy setting profile intervals moved towards the closer to described benchmark, interval is the least, choose and obtain N bar geologic section, its
In, N is positive integer；
Specifically, above-mentioned to meet pre-conditioned point can be the point that in geologic section, tectonic activity is relatively stable, so-called
Tectonic activity relatively stable there is no tomography, the most homogeneous point exactly.After determining initial point, can cut open with benchmark geology
The trend in face is moved towards as benchmark, the most on this basis, arbitrarily sets profile intervals, chooses n bar geologic section.Real in reality
The when of existing, may require that these geologic sections chosen radially distribute centered by initial point as far as possible, and avoid wearing as far as possible
Cross at the mature fault moving towards drastically to change or differ greatly.
When choosing of profile intervals, in order to improve precision and the range of research as much as possible, can be similar in trend
At the fault strike of Superimposed Basins to be measured (can be that the two angle is less than 30 °), suitably increase and choose；Trend is approximately perpendicular to treating
Survey (can be that the two angle is more than 60 °) at the fault strike of Superimposed Basins, suitably reduce and choose or do not take, to reduce work
Amount.
Further, the information such as the calculating parameter of each geologic section different times, azimuth can be calculated, and right
These information carry out sorting-out in statistics and form form, so that expressing apparent,
Step 104: calculate in described N bar geologic section every geologic section the one or more time each period interim
Expansion and contraction；
Because follow-up need draw be expansion and contraction rose, accordingly, it would be desirable to calculate every geologic section each time
The expansion and contraction of phase, such as, have chosen 21 geologic sections, then is accomplished by calculating these 21 geologic section each periods each
Expansion and contraction.
Step 105: according to described benchmark geologic section expansion and contraction in each period interim time one or more, and described N
Bar geologic section the one or more time each period interim expansion and contraction, draw that to characterize described Superimposed Basins to be measured structure dynamic
The rose in each period interim during the one or more of mechanics evolution Feature.
Rose is a kind of diagram in order to represent joint dimensional orientation and development degree thereof, the way one of rose
As be: first the joint in the range of a given area is carried out systematic survey, by the joint attitude recorded and density data spatially
Azimuthal spacings packet (such as: 5 ° or 10 ° is one group), and obtain the joint quantity often organized and average trend (or tendency), so
After, in the circle indicating geographic orientation, represent orientation, joint with radial direction, represent that this group saves with the long measure on radius
The quantity of reason, puts into each group of joint on figure, connects adjacent each subpoint, i.e. obtain the rose diagram of joint.Wherein, joint is represented
The figure of trend is called off to rose, only makees upper semi-circle；Represent that the figure of joint tendency is inclined to rose at joint, for wholecircle
Shape；Represent that the figure of dip of joint is dip of joint rose.
Rose is the common method of tectonic geometry research, such as tomography rose, the rose diagram of joint, is a kind of
Express the geometry diagram in orientation, have the advantages that method is simple, motivated, workable.But, tectonic kinematics and
The convenience of tectonodynamics research was also not introduced into rose.In this example, drafting can carry out Kinetic Characterization exactly
Expansion and contraction rose.
Drawing rose when, ultimately form is the rose in each period, if there being 4 periods, that
Finally give be 4 width Flos Rosae Rugosaes draw, every width rose be namely based on period all of geologic section expansion and contraction paint
System.That is, according to each period interim flexible during the one or more of every geologic section in N+1 bar geologic section
Rate, draws the described rose in each period interim time the one or more respectively.
Reality is implemented when, expansion and contraction rose can be drawn successively according to period, such as, first with the i-th period
For object of study, then so that in many group geologic sections, the expansion and contraction maximum in the i-th period is as radius, arbitrfary point is that the center of circle is drawn
Circle, finally, according to the azimuth of each section, draws radius respectively from the center of circle, i-th period of this section a length of of radius
The numerical value of expansion and contraction, then, couples each radius end points in order with straight line, if adjacent percentage of elongation is 0, then and should be with the center of circle
Couple, couple the percentage of elongation rose that the figure obtained was exactly the i-th period in this manner.
That is, the maximum of the expansion and contraction of described N+1 bar geologic section current period is determined；Using arbitrfary point as the center of circle, with
Described maximum draws circle as radius；Exist according to the expansion and contraction at the respective azimuth of described N+1 bar geologic section and current period
Expansion and contraction demarcation is proportionally carried out on circle；By calibrated point according to being linked in sequence, obtain the rose of current period.
It is to say, mapping when, it may be determined that a maximum expansion and contraction value, as radius, then its
Its expansion and contraction value is demarcated according to the proportionate relationship with maximum and is drawn, thus forms rose.
Further, so that it is more convenient to draw, decile can be carried out with pair radius, form multiple concentric circular, then
Drawing on the basis of concentrically ringed, so draw more convenient, result is the most accurate.I.e., it is possible to radius is divided into M
Part, wherein, M is the positive integer more than or equal to 2；Using arbitrfary point as the center of circle, M the radius obtained after decile is drawn as radius
Circle, obtains M concentric circular.
Finally obtained expansion and contraction rose characterizes the kinetics in this period, and for each period,
Having it is Regional contraction or the fixing form of expression of region stretching, extension, and this is cannot to show in rose, Flos Rosae Rugosae
Figure only performance expansion and contraction numerical value.In order to determine area type in each period, can be determined described to be measured folded by balanced cross section method
Closing basin area type in each period interim when the one or more, wherein, area type may include that Regional contraction
Or region stretching, extension.
Determining the area type in each period, and after obtaining the expansion and contraction rose in each period, it is possible to according to
Superimposed Basins to be measured is the area type in each period interim when one or more, and the Flos Rosae Rugosae in each period is drawn, and determines each
Stretch individual period or the direction of extruding.
In this example, introducing percentage of elongation rose and express Superimposed Basins tectonodynamics evolution Feature, this is mainly
In view of under the effect of complicated tectonic stress field, Superimposed Basins different azimuth all presents structural deformation in various degree and rings
Should, it is assumed that there are a homogeneous strain ellipse accepts uniform progressive deformation, the then law of conservation before and after its area follows deformation, non-stretches
Profile azimuth on exhibition (compression) direction there will be respective change, occurs certain angle to rotate, the i-th geologic section in period orientation
With i-th-1, i+1 phase geologic section orientation may be not quite identical, and the profile azimuth stretched on (compression) direction then will not
Rotate change.
After percentage of elongation (LVFS) rose is worked out, the orientation of the maximum section of percentage of elongation (LVFS) is can
As orientation, kinetics source.Therefore percentage of elongation (LVFS) rose can characterize kinetics direction, and percentage of elongation of many phases (shortens
Rate) there is characterizing the dynamic evolution of Superimposed Basins in rose combination.
In the above-described embodiments, on the basis of traditional rose establishment, add percentage of elongation (LVFS) factor,
Provide a method that for Superimposed Basins dynamic evolution, following effect can be reached: traditional rose is only limitted to structure
Study on Geometry, and percentage of elongation rose is tectonic kinematics, tectonodynamics research provides new method；Making of tradition structure
Kinetics walking direction rests essentially within qualitative aspect, and percentage of elongation rose is then table from sxemiquantitative-quantitative aspect
Levy kinetics direction.Tied mutually with earth history sedimentary evolution in period and pools' forming dynam-achievement in research by the achievement in research of this example
Close, favourable one-tenth can be evaluated and hide trap, oil-gas distribution etc., thus instruct oil-gas exploration and development.
Below in conjunction with a specific embodiment, above-mentioned Superimposed Basins tectonodynamics evolution characterizing method is illustrated, so
And it should be noted that this specific embodiment merely to the present invention is better described, it is not intended that the improper limit to the present invention
Fixed.
The concrete technical scheme of this invention is described as a example by the dynamic evolution characterizing method that certain caves in, it is assumed that this depression
It is completely covered by three dimensional seismic data, therefore can intercept the seismic profile of arbitrarily trend, and explain corresponding further
Geologic section.Carry out Kinetic Characterization based on this seismic profile may comprise steps of:
S1: this sunk area structural grain, major faults trend is moved towards for nearly NE, therefore, first chooses nearly NW trend
Section, utilizes balanced cross section method to work out tectonic evolution sections, is divided into E1f-E2d、E2s、E24 periods such as s latter stage, Ny-Qd, meter
Calculate corresponding percentage of elongation and be followed successively by 18.4%, 3.2% ,-4.3%, 7.1%, wherein, E2S latter stage is Regional contraction, can carry out
Erosion restoration is so that data are the most accurate.
S2: according to tectonic characteristic, the Y1 wellblock that in section, tectonic activity is relatively stable is set to initial point, sets trend near
The sampling interval being similar to NW is 5 °, and the sampling interval moving towards to be similar to NE is 30 °, chooses 22 sections altogether, and these sections are all worn
Cross Y1 wellblock, substantially avoided at the mature fault drastically changing through trend or differing greatly, collectively constitute as shown in Figure 2
" rice " font is distributed.
S3: repeat the calculation procedure in step S1, the azimuth of 22 geologic sections, the percentage of elongation in 4 periods are carried out
Sorting-out in statistics, and make certain depression main orientation section percentage of elongation in each period (compression ratio the is negative value) statistical table forming table 1 below:
Table 1
S4: first draw E1f-E2The percentage of elongation rose of d, specifically, maximum with the percentage of elongation in this period in 22 sections
