Description
Technical Field
The invention relates to the technical field of geological structure analysis, in particular to a method for determining the activity period of a small-scale sliding fracture in the underground of a basin.
Background
The distance between the glide and path fractures usually does not exceed several kilometers (Man P. Global fracture, classification and technical aspects of transportation-and recovery sessions on active and acquisition structure-slip fractures systems [ J ]. geographic facility, London, specific Publications,2007,290(1):13-142), which is a widely developed local structure, is a three-dimensional geologic body with a complex structure (Caine J S, Evans J P, for C. factory floor architecture and structural [ J ]. Geology,1996,24(11):1025 1028). Because the activity intensity is small and limited by the seismic data resolution, the activity period secondary analysis of the fractured basin underground case is one of the main technical difficulties. At present, the two methods commonly used for judging the sub-activity period of the underground sliding fracture of the basin are as follows:
1) fracture and stratum intersection relationship analysis methods (maqing, saxu, yulan, etc.. cis-topylor block in tower sliding fracture characteristics and oil control action [ J ] oil experimental geology 2012,34(2): 120-; zhongxin Source, Lu Xiu, Yang Nai Jun, et al. influence of the slide fracture of the north slope in the tower on the carbonate oil gas differential enrichment [ J ] Petroleum institute, 2013,34(4):628 and 637). The method is characterized in that the intersection relation between the structural style of the sliding fracture on the seismic section and the stratum unconformity surface is compared, and the activity period is judged based on the basic principle that the sliding fracture activity time is later than the fault stratum deposition time and earlier than the stratum deposition termination time.
2) Yanglian normal fault growth coefficient analysis method (Li Meng, Tang Liang Jie, Li Zongjie, etc.. selection of oil-gas exploration direction by sliding fracture characteristics-taking the north slope in the tower along 1 well region as an example [ J ]. Petroleum experimental geology 2016,38(1): 113-). 121). The method is based on the fact that when a shallow goose train normal fault is formed by sliding fracture or the phenomenon of activity accompanying deposition occurs, the deposition thickness of the upper and lower disks of strata of the goose train normal fault is inconsistent, and the thickness ratio of the deposition thickness to the deposition thickness is a growth coefficient. The larger the growth factor of the formation, the stronger the glide fracture activity at the time of its deposition.
Although the two methods are used by the prior people to try to judge the stage of the small-scale slippage distance slipping fracture activity in the underground basin, the application of the method depends on the prerequisites that the stratum is not integrated and the phenomenon of co-deposition is accompanied during the goose train activity, and the method is not suitable for the situations that the sign of stratum non-integration is not obvious (parallel non-integration) and the phenomenon of co-deposition is not obvious during the normal fault development of the goose train.
Disclosure of Invention

and S24, judging the ancient stress environment of the walking-sliding fracture activity according to the overall strain characteristics of the underlying vertical walking-sliding fracture section.
Further, in step S21, when the overlap between the adjacent sections of the lower standing slide segment rises, it indicates that the overlap is compressive strain, and when the overlap between the adjacent sections of the lower standing slide segment falls, it indicates that the overlap is tensile strain.
Further, the step S22 includes:
s221, acquiring vertical cross-sectional distances of the underlying vertical walking and sliding section along a plurality of cross sections perpendicular to the trend;
s222, performing statistical analysis on the acquired vertical cross section of the underlying vertical walking and sliding section, and determining the overall strain characteristics of the underlying vertical walking and sliding section.
Further, when the overall strain characteristic of the lower vertical walking and sliding section is compressive strain, it indicates that the ancient stress environment of walking and sliding fracture is mainly compressive stress, when the overall strain characteristic of the lower vertical walking and sliding section is tensile strain, it indicates that the ancient stress environment of walking and sliding fracture is mainly tensile stress, and when the overall strain characteristic of the lower vertical walking and sliding section is compressive strain and tensile strain evenly distributed along the lower vertical walking and sliding section, it indicates that the ancient stress environment of walking and sliding fracture is mainly shear stress.
Further, in the step S3, when the train angle of the train normal fault is 45 degrees, it indicates that the walking-sliding fracture moves in the shear stress environment; when the yankee angle of the yankee normal fault is less than 45 degrees, it indicates that the sliding fracture moves under the common stress environment of shearing force and tensile normal stress.
Further, when the paleo-stress environment corresponding to the step S2 is different from the paleo-stress environment corresponding to the step S3, or the slip direction is different, it indicates that the step has different stages of activities.
Further, the step S4 includes staging the sliding and breaking activities according to the penetrating horizon of the underlying sliding and overlaying goose train normal fault and the ancient stress environment determined in the steps S2 and S3.
Further, when the overlying goose rank normal fault exists at different layers, the arrangement mode of the overlying goose rank normal fault at different layers is different from the slip direction disclosed by the goose rank angle or the ancient stress environment is different, the sliding fracture activity is further classified according to the arrangement mode of the overlying goose rank normal fault at different layers and the goose rank angle.
Compared with the prior art, the method has the advantages that the method is based on a mechanical cause mechanism of forward fault fracture of the sliding fractured goose rows, and deduces the ancient stress background of the sliding fractured goose rows during formation or activity based on analysis of geometrical kinematic characteristics of the sliding segmented goose rows and the shallow goose row fault, so that the sliding fractured activities are staged.

Detailed Description

FIG. 1 shows a method for determining the number of medium and small scale glide fracture activity periods in the subsurface of a basin, according to an embodiment of the invention, comprising the following steps:
s1, acquiring a coherence attribute map of the walking-sliding fracture activity interface, and determining the longitudinal layering characteristics of the walking-sliding fracture by combining a profile map, and determining the development layer positions of the underlying vertical walking-sliding segment and the overlying goose train normal fault of the walking-sliding fracture zone;
s2, acquiring the sliding direction of the underlying upright sliding section and the ancient stress environment corresponding to the activity of the underlying upright sliding section;
s3, acquiring the sliding direction of the overlying goose train normal fault and an ancient stress environment corresponding to the overlying goose train normal fault activity;
s4, judging the stage number of the sliding fracture activity according to the sliding direction and the ancient stress environment corresponding to the activity of the underlying sliding section and the sliding direction and the ancient stress environment corresponding to the activity of the overlying goose train normal fault.
The method is based on a mechanical cause mechanism of forward fault fracture of the slipping fractured goose rows, deduces an ancient stress background during formation or activity of the walking and slipping fractured goose rows based on analysis of geometrical and kinematic characteristics of the walking and slipping segmented and shallow goose row fault, and stages the walking and slipping fractured activity. The method can be widely applied to secondary research of Claritong internal-walking sliding fracture active period. The existing sliding fracture activity staging method is mainly based on the fracture-stratum cutting relation and the fault growth coefficient method, and is not suitable for the conditions that the stratum non-integration mark is not obvious (parallel non-integration) and the goose-rank fault moves in the continuously deposited stratum.
The invention is mainly based on the mechanical mechanism that deep sliding fracture surface activity leads to formation of shallow goose train normal fault, as shown in fig. 2 and fig. 3. Wherein, in figure 2, σnDenotes the tensile stress, σ, perpendicular to the fracture planesThe shear stress acting on the fracture surface is shown, A represents the glide fracture surface, and B represents the normal fault of the goose train. In fig. 3, reference numeral 1 denotes a deep slipping fracture, and reference numeral 2 denotes a shallow goose row normal fault. When the deep sliding fracture surface moves in a stress environment of simple shearing, the formed normal fault goose row angle is 45 degrees; when tensile stress vertical to the fracture surface exists, the formed goose row normal fault goose row angle is less than 45 degrees. In addition, the spreading mode of the goose-row normal fault layer can also reveal the movement direction of the deep sliding fracture surface (fig. 3). The fracture mechanics principle is generally used for shear band-related outcrop research, and no precedent is given for judging the activity period of underground slip fracture.
In one embodiment, the step S2 includes:
s21, acquiring the strain type of the lap joint part between the adjacent sections of the underlying vertical walking and sliding section;
s22, acquiring the overall strain characteristics of the underlying upright walking and sliding section;
s23, judging the sliding direction of the lower vertical sliding and breaking according to the step of the lower vertical sliding and sectional arrangement and the strain type of the splicing part;
and S24, judging the ancient stress environment of the walking-sliding fracture activity according to the overall strain characteristics of the underlying vertical walking-sliding fracture section.
In one embodiment, in step S21, the overlap between adjacent sections of the underlying upright slide-off segment is indicated as compressive strain when the overlap is raised and tensile strain when the overlap between adjacent sections of the underlying upright slide-off segment is depressed.
In one embodiment, the step S22 includes:
s221, acquiring vertical cross-sectional distances of the underlying vertical walking and sliding section along a plurality of cross sections perpendicular to the trend;
s222, performing statistical analysis on the acquired vertical cross section of the underlying vertical walking and sliding section, and determining the overall strain characteristics of the underlying vertical walking and sliding section.
In one embodiment, when the overall strain characteristic of the underlying vertical sliding segment is compressive strain, it indicates that the paleo-stress environment of the sliding fracture is dominated by compressive stress, when the overall strain characteristic of the underlying vertical sliding segment is tensile strain, it indicates that the paleo-stress environment of the sliding fracture is dominated by tensile stress, and when the overall strain characteristic of the underlying vertical sliding segment is compressive strain and tensile strain evenly distributed along the underlying vertical sliding segment, it indicates that the paleo-stress environment of the sliding fracture is dominated by shear stress.
In one embodiment, the step S3, when the yankee angle of the yankee normal fault is 45 degrees, indicates that the walking-sliding fracture is active in a shear stress environment; when the yankee angle of the yankee normal fault is less than 45 degrees, it indicates that the sliding fracture moves under the common stress environment of shearing force and tensile normal stress.
In one embodiment, when the paleo-stress environment corresponding to the step S2 is different from the paleo-stress environment corresponding to the step S3, or the slip direction is different, it indicates that there is different stages of the step S.
In one embodiment, the step S4 includes staging the glide and fracture activities according to the penetration horizon of the underlying glide and overlying goose train normal fault, and in combination with the paleo-stress environment determined in the steps S2 and S3.
In one embodiment, when the overlaid wild goose rank normal fault exists at different layers (namely, a plurality of overlaid wild goose rank normal faults exist at different layers), and the arrangement mode of the overlaid wild goose rank normal fault at different layers is different from the slip direction disclosed by the wild goose rank angle or the ancient stress environment is different, the sliding fracture activity is further classified according to the arrangement mode of the overlaid wild goose rank normal fault at different layers and the wild goose rank angle.
In a specific example, this example performed a campaign analysis of the north 5 fault zone in the north of the Tarim basin, aligned. The northward 5 th fracture zone covers the northward 8 th and the northward 8 th three-dimensional regions.
And extracting a coherence attribute map and a seismic section map of a main fracture interface (taking a cis-8-North three-dimensional 2000-6000 data volume T74 interface as an example) according to the seismic three-dimensional data. And (3) defining the longitudinal layering characteristics of the walking-sliding fracture, and defining the development layer positions of the underlying vertical walking-sliding segment and the overlying goose train normal fault in the walking-sliding fracture belt. And a coherent attribute map of the underlying vertical walking-sliding segment is finely interpreted, and the strain type of the overlapped part between the adjacent segments of the underlying vertical walking-sliding segment is analyzed. As shown in fig. 4 (a), a fine interpretation of the underlying upright slip segment for a north-8 three-dimensional fracture in the north-5 fracture zone is shown. In fig. 4, the arrow points are shown upward to indicate compressive strain when the overlap between adjacent sections of the underlying upright slide segment rises and downward to indicate tensile strain when the overlap between adjacent sections of the underlying upright slide segment is depressed. And then, according to the step type of the sectional arrangement of the underlying vertical walking and sliding and the strain type of the splicing part, the sliding direction of the underlying vertical walking and sliding fracture is judged to be right. Specifically, according to the sliding fracture kinematics principle, the splicing bulge develops in a segmented splicing region with a segmented arrangement step type opposite to the row direction, namely left-step right-row or right-step left-row; the splicing and pulling development is carried out in a segmented splicing area with the same segmented arrangement step and row direction, namely left-step left row or right-step right row. In this case, the left step spread is segmented and the development of the overlap joint is raised, so that the right walking slip can be judged. Fig. 4 (b) shows a structural view of section 13, from which the vertical distance of the fracture perpendicular to the course can be derived.
As shown in the figure5, (a) to (b) shows that the three-dimensional fracture in the 8-north direction is at T7 4The interface (top surface of the central aotao system) develops sliding segments. T is shown in FIGS. 5 (c) to (d)7 0The interface (top of Odoodun) develops the normal fault of the Yan train. Obtaining T7 4The vertical section distance of the interface vertical sliding section along a plurality of sections vertical to the trend is used for the acquired T7 4The vertical fault distance of the interface vertical sliding section is subjected to statistical analysis to determine T7 4The overall strain characteristics of the interface vertical sliding segment, and the statistical analysis result is shown in (e) in FIG. 5, T7 4The interface sliding segment is formed under the oblique pressure (pressure torsion) environment. T shown in FIGS. 5 (c) to (d)7 0Arrangement mode of interface goose row normal fault, known as T7 0The interface goose column is moving on the right fault left. T is shown in FIG. 5 (f)7 0Statistical analysis result of Yan rank angle of interface Yan rank normal fault, average value of Yan rank angle beta<45 deg. to indicate T7 0The interface goose row normal fault is formed in an inclined pulling (tension-torsion) environment, and a walking sliding section is subjected to the action of tensile normal stress when the interface goose row normal fault is formed.
Synthesis of the above analysis, T7 4The interface sliding section firstly moves to the right in an oblique compressive stress environment and then moves to the left in an oblique tensile stress environment, so that T shown in (c) to (d) of fig. 5 is formed7 0Interface yanglian normal fault.
In the above analysis, T7 4Interface sliding segment and T7 0The ancient stress environments corresponding to the interface goose row normal fault activities are different, and the walking and sliding fracture has activities of different periods. Can be further matched with T according to the profile characteristics of the sliding fracture7 4Interface sliding segment and T7 0The activity of the interface yanglian normal fault is staged. As shown in fig. 6, according to the through layer positions of the north 5 breaking belt underburden sliding sections and the overlaid goose-row normal fault, dark lines and arrows in the figure indicate underburden sliding sections, and light lines and arrows in the figure indicate overlaid goose-row normal fault. T disclosed in conjunction with FIG. 57 4Interface sliding segment and T7 0The ancient stress environment corresponding to the interface yan train normal fault activity shows that T is7 4The activity time of the interface sliding segment in the oblique pressure stress environment corresponds to late Olympic, namely the III screen in the middle of Jia Li Dong, and then the interface sliding segment moves again in the oblique tension stress environment at the late of Jia Li Dong (Shiken) and causes the formation of normal fault of the goose train.
After the above analysis, the portion of the northward 5-th fracture zone in the three-dimensional region of cis 8 can be further analyzed. As shown in fig. 7, in the cis-8 three-dimensional fracture longitudinal stratification feature, the overlying goose-row normal fault exists at different levels, and as can be seen from (a) to (f) and the section views (g) to (h) in fig. 7, the overlying goose-row normal fault exists at T7 0Interface and T6 0Interface (top surface of mud basin system in middle and lower), and T7 0Interface and T6 0The arrangement modes of the normal fault of the goose rows on the interface are different, and the slip directions revealed by the goose rows are different, so that the T is the basis7 0Interface and T6 0The arrangement mode of the overlying goose train normal fault and the goose train angle on the interface further stages the sliding fracture activity, so that the method can further determine that the forward 8 north three-dimensional fracture in the forward north 5 fracture zone moves to the right at the late stage of the Jia-Li east and then moves to the left at the early stage of the Hai-West.
In summary, at least three phases of activity were determined for the north 5 breaker: middle stage of Jia Li Dong, late stage of Jia Li Dong, and early stage of Haxi. The activity characteristics of the north-ward 5 fracture in the third stage are respectively: the lower-based walking and sliding sectional right-going movement under the condition of III curtain oblique pressure (pressure torsion) stress at the middle stage of Jia-Dong is accompanied by the formation of a shallow left-stage spread wild goose array normal fault at the later stage of Jia-Dong in the condition of diagonal tension (tension torsion) stress, and the lower-based walking and sliding sectional left-going movement under the condition of Hai-West is accompanied by the formation of a right-stage spread wild goose array normal fault at the early stage of Hai-West.
The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily make changes or variations within the technical scope of the present invention disclosed, and such changes or variations should be covered within the scope of the present invention.
