Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached in the embodiment of the present invention
Figure, the technical scheme in the embodiment of the present invention is clearly and completely described.It should be appreciated that being retouched below with reference to accompanying drawing
The embodiment stated is exemplary, is only used for explaining the present invention, and is not considered as limiting the invention.
The embodiments of the invention provide a kind of simple stratified geological objects three-dimensional geological based on the coupling of the multi-source datas such as drilling
Modeling method.Various data constraints are come in, existing data source is sufficiently make use of, modeling result is more kissed with actual conditions
Close, accuracy is higher, particularly stratal pinch-outs drilling, lenticular body, the complicated geological phenomenon such as layer interlayer control.
It refer to Fig. 1, the stratified geological objects modeling method of the multi-source data coupling on stratum containing standard of the embodiment of the present invention, its
Comprise the following steps：
Step a), selection modeling region, extract multi-source data and are coupled., may for specific modeling region
There is substantial amounts of geological information, these information are although various, but it is relatively regular, it can be stored in database, form specific region
Attribute data storehouse in case reuse.When user builds the three dimension strata model in modeling region, the brill in region can extract
The related information of hole data, cross-sectional data and other altitude datas, such as contour, elevational point, and carry out coupling merger processing,
Them is turned into the valid data during three-dimensional geological modeling, be that the structure of model establishes data basis.The modeling method
In practical application, for specific modeling region, numerous drilling is might have, the information that these drillings can be provided
Hierarchical information of position (geographical coordinate) including each drilling, the type of drilling and stratum etc..In view of some information
Distribution of boreholes is closeer, and used drilling hole amount is huge when being modeled in the range of a wide range of or even whole research area, can not only reduce
Modeling efficiency, is also unfavorable for the analysis and research to model, at this moment it is contemplated that drilling is classified according to certain net degree, when entering
During row modeling according to the size (can one standard of predefined) of modeling scope calculate used in drilling rank, Ran Houzai
Extracting the borehole data of appropriate level is used to model.
Step b), use the borehole data in the multi-source data that step a) extracts with building the region of covering whole modeling region
Sequence table layer by layer.One notable feature on stratum be it into " layer " property, belong to the stratum of same " layer " have it is unanimous on the whole
Sedimentary Age and mechanics index of physics, same type of material is can be regarded as to a certain extent.The layering of borehole data
Information is the description of the contact surface to neighbouring stratum, can disclose vertical distribution situation of the stratum at bore position.Time
Drillings all in modeling region are gone through, is picked out and is disclosed a most drilling of rock stratum information and make the formation information of this drilling
For initial stratigraphic sequence table, then this sequence table is compared one by one with residue drilling, if sequence is inconsistent, sequence is updated
Table, if unanimously, skipping Present Borehole, continues more next drilling, so repeatedly, and it is complete that modeling region is covered in generation one
The regional stratum sequence table on portion stratum, in case follow-up modeling is used.Carrying out the rule of stratum numbering is：, to old, successively passed from newly
Increase.I.e. newest stratum numbering is 1, is then gradually incremented by according to stratum age.
Step c), borehole formation aspect is numbered.Each stratum and region in region in each drilling will be modeled
Stratigraphic sequence table is contrasted, and is determined the sequence number of each formation beds in each drilling, is ignored non-existent stratum in the drilling.Compile
Number rule is：From top to bottom, since 0.That is the serial number 0 of drilling top formation beds (ground surface), with each in drilling
Stratum is corresponding in regional stratum sequence table to number to specify the numbering of the formation beds of the stratum bottom surface in drilling.Separately
Outside, do not have influential, insignificant substratum on final modeling result, merger processing can be carried out in borehole formation aspect numbering,
Do not considered during actual modeling.
Step d), the aspect template on each stratum of generation.The generation of each formation beds template, refers to in the formation beds
On the basis of the aperture coordinate of all drillings, with reference to modeling regional boundary condition, one generated using the triangulation of standard
The individual triangulation network.The formation beds template define not only the external boundary of three dimension strata model to be built, additionally it is possible to expression modeling
The topological relation of each formation beds of region.It is considered as being to determine one " template " of modeling regional stratum topological relation,
Can from top to bottom it put off along drilling depth to whole stratum in modeling region.It can so ensure that each formation beds has
Topological relation determine, unanimous between the higher and lower levels, can greatly simplify the complexity of subsequent treatment, strengthen the robustness of algorithm.
Step e), using multi-source data row interpolation is entered to formation beds elevation.The bed boundary of TIN formation
Although can truly reflect display situation, due to the inhomogeneity of data, the curved surface of formation often very irregular need to be inserted
Value is smooth.Kriging regression method is used in the embodiment of the present invention, using the multi-source data of extracted coupling to the stratum of generation
Aspect carries out smooth.Extract the elevation information at each formation beds control point respectively, including data in bore database and cut open
Control point data in the figure of face, using these point interpolations ask various regions layer by layer on face die plate each unknown point height value；If ground
The point on face die plate is consistent with the two-dimensional plane coordinate drilled layer by layer, then the elevation of the point and the stratigraphic controls point disclosed in drilling
Elevation is consistent, it is not necessary to interpolation.The main feature that Kriging regression is different from other spatial interpolation methods is, to the sky of variable
Between correlation analyzed and utilized, can more objectively reflect geological phenomenon, the simple and direct practicality of algorithm, with certain extrapolation energy
Power, application effect is good.
Step f), the intersecting processing of progress formation beds, then adjust stratum elevation.When carrying out interpolation fitting to stratum,
The data on correspondence stratum are only considered, interpolation and the fitting on each stratum are independent progress, thus do not account for adjacent earth formations
Crossover phenomenon between face.It so may result in form the cross one another situation of multilayer digital elevation, this does not obviously square with the fact,
Accordingly, it would be desirable to the intersecting processing of formation beds be carried out, so that the local height value adjustment of the understratum for follow-up intersecting stratum
Lay the foundation.Stratum template after the intersecting processing of formation beds, it is possible that the point that should be located on understratum
Elevation, but higher than the stratum above it, this needs to adjust stratum elevation, pulls it back on the elevation equal with its last layer.
This process is completed by comparing the corresponding point of each formation beds.For the specified point in specific formation beds
TriPnti, its height value is Zi, the corresponding points TriPnt in a formation beds thereon can be retrievedi-1Height value Zi-1If,
ZiMore than Zi-1, it is necessary to by ZiAgain it is entered as Zi-1, so just can guarantee that up and down the uniformity of surface layer order relation layer by layer.
Step g), structure three-dimensional formation physical model.Generate after each formation beds triangulation network, it is necessary to will be neighbouring
The triangulation network of formation beds unites by a seam on vertical, you can constitute complete three-dimensional formation physical model.Only need to top layer or
A triangle in bottom formation beds is all triangles on starting point, each stratum of circular treatment and each formation beds
Shape can be completed.
In the embodiment of the present invention, the extracted data model with after coupling of multi-source data mainly has two kinds in step a)：Ground
Particle key element and geology line feature.Drilling and stratum isopleth data form ground particle feature model after extracting；Profile, geology
Stage casing figure and geological structure diagram data can generate ground particle feature model and geology line feature model after extracting.Each class data are all
The plug-in unit extracted by a data, which is realized, to be extracted, and data are generated corresponding point key element and line feature model by all plug-in units,
These key elements are subjected to coupling processing again afterwards.Fig. 2 is refer to, the specific method for extracting multi-source data and being coupled is：
Step s1), the extraction of the main multi-source data such as drilling.For borehole data, due to drill purpose and it is affiliated specially
The difference of industry causes the form of borehole data to have differences, but drill hole information has relative normalization again, it is therefore desirable to set
The reasonable efficient bore database of meter one, is arranged and is standardized to original borehole data, borehole data is realized with this
Integrated management, it is ensured that the validity and completeness of original drill hole information.Cross-sectional data is produced by two ways：One kind is user
By borehole data hand drawn profile, there is the possibility of mistake than larger as modelling data source in this data；It is another
It is that the knowledge such as expert's interpretation and Engineering borderline tracking is combined together using program to plant, and automatically generates the main body frame of profile,
Connection and the editor for carrying out hatching on this basis by professional again.Obtaining terrestrial reference isopleth data typically has two kinds of sides
Method：One kind is by geology personnel's manual drawing；Another is to enter row interpolation tracking by computer to form.
Step s2), the generation of three-dimensional geological key element.Will drilling point data, section diagram data, isopleth data and plane earth
Matter diagram data etc. is converted into three-dimensional geological key element：Drill key element, section key element, geological plane maps key element etc..
Wherein, the process of the generation of drilling key element actually drilling modeling, the drilling includes straight hole data and oblique
Hole data.The embodiment of the present invention is by taking inclined hole as an example, and straight hole is considered as a kind of its special case.From earth's surface to underground, inclined hole needs note
Record the buried depth and angle (zenith angle and azimuth) of each point.If hell coordinate is P0(x0, y0, z0), each point of underground
Depth be DEPi, and zenith angle and azimuth are respectively AiAnd Bi, then each point of underground Pi(xi, yi, zi) coordinate be：
xi=x0-DEPi*tg(Ai)*cos(Bi)
yi=y0-DEPi*tg(Ai)*sin(Bi)
zi=z0-DEPi
According to P0、P1、…、Pi... coordinate can set up the pipeline model of drilling.
The geologic datas such as the earth's surface isopleth data, planogram data, are present in the form of two-dimensional visualization
In map, it need to be changed to three-dimensional coordinate.Because the line feature of isopleth data has Height attribute field, its two-dimensional line holds very much
Easily it is converted into three-dimensional line.For plane geologic data, it is necessary to which each key element on two-dimensional structure (point) line is carried out into linear translation,
The three-dimensional coordinate matched is obtained, then height value is adjusted in the three-dimensional model.
For two-dimensional cross section, profile is matched with three-dimensional drilling, and then the three-dimensional coordinate put on reference section line,
Comparatively it is more difficult.In embodiments of the present invention, profile is positioned using survey line, according to position of the hatching in profile
And the actual coordinate value positioning the entire profile position in space in space, if known to two in profile of hatching
Coordinate points are P0(mx0, my0) and P1(mx1, my1), two coordinate points Ks of the corresponding hatching in section space0(fx0, fy0,
fz0) and K1(fx1, fy1, fz1).Then the corresponding three-dimensional in arbitrfary point (x, y) in two dimensional cross-section can be calculated according to similar triangles theorem
Coordinate points P (X, Y, Z)：
Map represents map reference, is abbreviated as m, and fact represents actual coordinate, writes a Chinese character in simplified form f.
Therefore, in above-mentioned formula：
mx0、my0Abscissa, the ordinate in geographical base map two dimensional cross-section on certain point diagram are represented respectively；
mx1、my1Abscissa, the ordinate in geographical base map two dimensional cross-section on another point diagram are represented respectively；
fx0、fy0、fz0The actual abscissa of D profile space point, ordinate, elevation are represented respectively；
fx1、fy1、fz1The actual abscissa of another point in D profile space, ordinate, elevation are represented respectively.
According to above-mentioned coordinate transformation formula, two dimensional cross-section line is converted into D profile line, then hang up it is existing up and down
Layer attribute, forms section line feature；On the basis of section line feature, the ground layer line to closing carries out triangulation, forms son
Face, hangs up attribute formation cross-sectional area key element.
Step s3), the coupling processing of multi-source data.Data coupling is carried out to three-dimensional geological key element, three new dimensions are formed
According to key element：Ground particle key element, geology line feature.Carry out the stratum containing standard complex layered geology three-dimensional modeling when, it is necessary to according to
Attribute conditions and steric requirements search ground particle and geology line feature, are then modeled.
Drilling, stratum top plate isogram and profile are to be completed by different professionals in different times, therefore,
During the multi-source data coupling processing is carried out, there can be certain contradiction.When there is contradiction, it is necessary to enter to data
Row consistency adjustment.Because borehole data is relatively believable data, during the principle of stratum inconsistency adjustment, to drill
It is basic control framework, the other data sources of adjustment with cross-sectional data.
It refer in Fig. 3, the embodiment of the present invention, when carrying out intersecting processing to formation beds, each formation beds is
By many triangle sets into determining whether there is intersecting between two formation beds models, it is necessary to carry out a large amount of triangle pairs
Intersecting detection, therefore, formation beds cap is relatively time consuming.The method of the intersecting processing of formation beds is in step f)：
Using the collision detection algorithm based on AABB-OBB borders, collision detection is carried out to the formation beds triangulation network, comprised the following steps that：
Step 1), in units of single formation beds build formation beds AABB detection storehouse detected, it is assumed that model
Include N number of stratum in region, then need to build the AABB detections storehouse of N number of formation beds.
Step 2), only projections of two AABB in three reference axis just to can be regarded as two AABB when having overlapping intersecting,
Detect that storehouse and other AABB detect that the AABB between storehouse, to being compared, finds out intersecting AABB pairs, n to n-th of AABB accordingly
Initial value be 1, if not intersecting between two AABB pairs of formation beds, constitute stratal surface triangle be also impossible to phase
Hand over.
Step 3), blow intersecting AABB pairs, set up in units of triangle OBB detection storehouse carry out collision detection, find out
The triangle pair intersected in corresponding OBB.
Step 4), more accurate positioning intersection algorithm is carried out to intersecting triangle, judge whether it really intersecting, and ask
Go out intersection point.
Step 5), the triangle that is detected in the aspect of understratum is deleted, using step 4) in the intersection point that calculates as new
Control point, triangulation is re-started to understratum aspect.
Step 6), judge whether to have traveled through all formation beds, if not having, return to step 2) restart circulation, if
Compare, then intersected processing and complete.
Above content is to combine the further description that specific embodiment is done to the present invention, it is impossible to assert this hair
Bright specific implementation is confined to these explanations.For the those of ordinary skill of the technical field belonging to the present invention, not
On the premise of departing from present inventive concept, some simple deduction or replace can also be made, are regarded as belonging to the protection of the present invention
