Embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings：
The method of this quantitatively characterizing fault combination reliability is by accurately determining the type of fault growth now and the raw station of segmentation
Point, and then application fault plane is segmented the reliability of growth quantitative evaluation method quantitatively characterizing fault combination, with reference to Fig. 1, specifically
It is as follows：
1st, fault growth type and segmentation growing point are determined
（1）As shown in figure 1, the present embodiment（The embodiment of the present invention is that secrecy is carried out）First in step S101, with dimensionally
Based on shake data or structural map, acquisition cuts section buried depth along a certain fault strike Different Strata diverse location coordinate and upper lower burrs
Data；
（2）Differentiate fault growth type and segmentation growing point using " two figures "
Based on step（1）The data of acquirement, draw " two figures of tomography（Turn-off-distance Curve and fault plane turn-off isopleth）”；
It is that typical fault throw-distance Curve determines fault pattern and segmentation growth point diagram shown in Fig. 2, its low value area represents segmentation life
Long tie point, 4 segmentation growing points of the mature fault, shows as 5 sections of connection growth characteristics.Fig. 3 is the too northern exploitation of Daqing placanticline
F074 fault plane turn-off isopleth in area determines fault pattern and segmentation growth point diagram, and its " saddle " represents Fault segmentation growing point,
F074 tomographies show as two-part growth characteristics.Therefore, can be effective using turn-off-distance Curve or fault plane turn-off isopleth
Differentiate the growth type and segmentation growing point of tomography.
2nd, the reliability of Quantitative Evaluation on Fault combination
（1）Obtain evaluating
For " being flexible coupling " side row superimposition tomography, transition shift（D）Refer to the fault displcement sum of superimposition faulted section center two,
Separation refers to the vertical range between the tomography of superimposition faulted section center two（Fig. 4 A）；For Hard link tomography, transition shift is disconnected
Layer A is with withering away（abandoned）Tomography B superimposition section center two fault displcement sum, separation refers to tomography A and extinction
（abandoned）Distance between the tomography of tomography B superimposition section center two（Fig. 4 B）；If due to seismic resolution limitation, disappeared
The possible agensis of tomography B is died, transition shift is equal to displacement in the middle part of fault strike mutation section.
（2）Using the reliability of fault plane combined basis weight discrimination standard corrected tomography
Fault growth generally undergo it is isolated, be flexible coupling and 3 stages of Hard link；Based on transition shift（D）With separation（S）Two is big disconnected
Layer relevant parameter, establishes fault plane combined basis weight discrimination standard（Fig. 5）, when D/S is less than 0.27, faulted section is arranged in side
In the superimposition stage-" being flexible coupling " stage, when D/S is between 0.27-1, in collapse stage-" being flexible coupling " stage is started, work as D/S
During more than 1, fracture is in and is completely severed stage-" Hard link " stage（Fig. 5）.
Xing Bei development zones 278+273 tomographies are original to be construed to two Hard link tomographies, 278 mature fault end extinction tomographies
（Fig. 6 a）.Quantitative identification standard is grown based on Fault segmentation, Xing Bei development zones 278+273 is broken in 3. number waypoint
（Trace1021）D/S is 0.55（Table 1）, two tomographies should be at " being flexible coupling " stage in Saar oil reservoir top surface --- start brokenly
Split the stage.And 1., 2. and 4. a number segmentation growing point D/S values are all higher than 1（Table 1：Saar oil reservoir top surface 278+273 tomographies are changed
Displacement and separation relation）, in " Hard link " stage（Fig. 6）.
Table 1
3rd, seismic profile Fine structural interpretation is verified
With reference to 3. number waypoint superimposition area seismic fine interpretation section, it was demonstrated that 278 and 273 fracture superimposition area's seismic reflections are continuous
（Fig. 7）, therefore, the tomography is made up of 278 tomographies and 273 fracture side row superimposition.
Using method proposed by the present invention, can with the reliability of effective execution seismic interpretation so that for disconnected circle Type division,
Sealed harmonic drive lays the foundation, while the guidance of theoretical and method also is provided for the risk of effectively reduction oil-gas exploration and development,
With good promotion prospect.
Above-mentioned technical proposal is one embodiment of the present invention, but described content is only to facilitate understand this hair
It is bright and use embodiment, be not limited to the present invention.Any those skilled in the art to which this invention pertains, not
Depart from disclosed herein spirit and scope on the premise of, can make in the formal and details of implementation any modification with
Change, but the scope of patent protection of the present invention, still should be subject to the scope of the claims as defined in the appended claims.
