Specific embodiment
Embodiment 1
The selected basin South Atlantic Ocean Sang Tuosi is target area, and embodiment 1 provides Carbonate Reservoir structure under a kind of deep water salt
The means of interpretation made, comprising the following steps:
Step S1: the tectonic setting analysis of Carbonate Reservoir under deep water salt
The geological structure in carbonate rock oil field shapes complicated under deep water salt, in order to construct carry out reasonable dismissal to it, with bright
Construction phase locating for true interval of interest, it is therefore desirable to first carry out tectonic setting analysis, including following two step:
Step S11: the tectonic setting in the basin Sang Tuosi tectonic movement analysis: is divided into late sieve dwarf-Early Creataceous Epoch rift valley
Phase, Aptian transitional period in Early Creataceous Epoch and Upper Cretaceous-drift episode three phases of new generation, as shown in Figure 1,
Rift early stage from Late Jurassic to Early Creataceous Epoch A Pu, South Atlantic Ocean just starts to split, in Brazilian east
It is coastal to form a series of rift basin；Early Creataceous Epoch A Pu mid-term enters the transitional period, and South Atlantic Ocean is split completely, Africa
Plate and South American Plate are kept completely separate and start to drift about；After Aptian, African Plate northwards drifts about, South American Plate to
Southwest drift, into drift episode, the quick invasion of lasting heat sink drop and seawater from that point on, Brazil is the same as the sea between Africa
It is more and more openr.
Step S12: tectonic style analysis, by rift tectonic setting under salt be divided into fault-depression stage, the disconnected col conversion stage and
Down warping region stage three phases, as shown in Figure 2, the interval of interest of this example are in rift under salt, therefore further to splitting under salt
The paddy phase is analyzed.
Fault-depression stage: faulting is strong, basement block differential fluctuation and tilting deformation, shows to build the alternate rift of moat
Structure, block stretch the characteristics of rate and subsiding extent are all very big, and the province of the Yuan Dynasty depth of water is presented in depositional environment, develop huge thickness
Based on Picarrss group Lacustrine Strata, wherein deep lacustrine facies mud shale and marl are basin main hydrocarbon source rocks；
Disconnected col converts the stage: fault activities weaken in block, and extending position phase shift is to being evenly distributed on different tomographies, ground
Shape height difference is small, shows the structure of down warping region, deposit filling ITP group stratum, and profundal zone is lacustrine shale, marl (another set of hydrocarbon
Source rock) deposition, phytal zone development shell limestone, ITP group shell limestone is one of basin Yan Xia main force reservoir；
The down warping region stage: fault development is few and movable faint in area, develops the BVE group stratum of Stable distritation, and lithology is folded with algae
It is another set of main force's reservoir under the salt of basin based on layer limestone.
It follows that fault-depression stage, faulting is strong, and substrate and the development of reservoir bottom fault, are in rift structure；Disconnected col
Conversion stage and down warping region stage, fault activities weaken, and fault development is few, therefore tomography agensis at the top of reservoir, pass through the analysis
It lays the foundation for the foundation of subsequent fault pattern.
Step S2: layer analysis:
Well seismic profile is crossed to typical case and carries out the seismic phase analysis of reef beach (see Fig. 3 (a)), interval of interest is divided into positioned at lower part
Beach phase reservoir and superposed reef facies reservoir,
Wherein, beach phase reservoir in weak amplitude clutter reflectance signature in mound shape-, vertically and horizontally fold by the more phases time on substrate that are laid in
Add growth；Reef facies reservoir, reef core compared with continuous reflection, are coated on shell beach, more phases time are folded in amplitude low frequency strong in mound shape-
Add and builds grand growth structure.Accordingly, crossing well profile analysis by typical case can be obtained reef flat facies identification plate (see Fig. 3 (b)), and then shape
At reef flat facies sedimentary origin ideograph；
Step S21: reef flat facies identification is carried out using reef flat facies identification plate, specifies different sedimentary micros；
By reef flat facies identification plate it is found that different sedimentary micros corresponds to different typical earthquake phase characters, therefore is cuing open
In face, by sorting out typical characteristics of seismic, different sedimentary micros is specified；
Step S22: the analysis of reef flat facies sedimentary origin is carried out using reef flat facies sedimentary origin ideograph；
Since Lacustrine Carbonates are deposited on different times development with different genetic models, as early development is raw under salt
Consider beach deposition to be worth doing, advanced stage develops microorganism reef deposit, different sedimentary subfacies or even microfacies and develops in different parts, is reflected in and is deposited into
Because also different in terms of mode.
In early days, Lacustrine Carbonates deposition is based on raw bits beach parfacies deposition under salt, as shown in Fig. 4 (a), raw bits beach parfacies
Deposition need its underpart there are a more firm pedestal, convenient for the fixed growth of shell biology, these pedestals usually with
Based on the stratum of rift consolidation or magmatic rock after cooling.The more single high-quality shell limestone major developmental of ingredient is depositing
Among the shell beach microfacies at the relatively high position (arriving alar part at the top of rumble strip) of phase construction.Into beach body, side is (at the top of rumble strip
Relatively quiet land regions) microfacies between beach is developed, it is raised that grey cement content is gradually developed to the external side in beach (below rumble strip)
Beach edge deposition, the energy of two microfacies is lower than shell beach, therefore shell shell is saved relatively complete by less upheaval and abrasion
Whole, lithology is particle-supported containing based on plaster/ash shale shell limestone to point contact with matrix support.Continue lower to energy
Slope foot position, water body environment is unfavorable for the breeding of shell biology, therefore develops the beach slope-based on micrite or even mud stone
Shore Vlei deposition.
In advanced stage, Lacustrine Carbonates deposition is based on microorganism reef laminated limestone deposition under salt, as shown in Fig. 4 (b), this
Parfacies is deposited on opposite lake level lower period, and therefore, the development range of microorganism reef is more more extensive than raw bits beach, but reefs
Form and scale be similarly subjected to its water energy for developing position and influence, and stromatolite is also required to develop in solid pedestal
On.Laminated limestone major developmental constructs relatively high position (rumble strip alar part) in the deposition phase, is the master of reef core microfacies
Want component part.Position (relatively quiet land regions at the top of rumble strip) microfacies between reef between reefs and beach body, deposition
It is that reef front is micro- to reefs outside (below rumble strip) based on the relatively poor laminated limestone of pelleted limestone and development degree
Phase deposits based on grey cement content slightly higher pelleted limestone and laminated limestone.To the lower position of energy, deposit with micrite
Or even the reef slope based on mud stone-shore Vlei deposition.
Step S3: Magmatic Rocks type analysis, the interval that has a definite purpose develop intrusive rock and the two kinds of magma of effusive rock altogether
Rock, as shown in Figure 5；Intrusive rock and effusive rock are all non-reservoir, and at the top of reservoir, effusive rock is erupted in reservoir bottom for intrusive rock intrusion
There is certain influence in portion on the structure interpretation in Reservoir Section, it is therefore desirable to which the distribution of clear intrusive rock and effusive rock is constructing
Paid attention in interpretation process.
Step S4: magmatic rock identification plate is established, the seismic response features of intrusive rock and effusive rock are specified
Well profile analysis is crossed by typical case, specifies the seismic response features of intrusive rock and effusive rock, establishes magmatic rock identification
Plate is constructing as shown in fig. 6, typical earthquake response characteristic corresponding with plate is corresponding magmatic rock after establishing plate
It explains and is paid attention in section.
Step S5: clear magma analysis the distribution of igneous rocks rule: is tracked based on wideband inverting data volume application Geobody body
The rock regularity of distribution, is shown in Fig. 7, specifically includes the following steps: the tracking of Geobody body is that the body carried in Petrel software tracks function
Can, on the basis of inverting data volume, seed point is given, the value that will be greater than the seed point is tracked, and obtains the distribution of magmatic rock
Range.
Step S51: low frequency model is established using FWI speed, completes wideband inverting；
FWI speed passes through the speed that full waveform inversion obtains, and full waveform inversion is more leading algorithm at present, is passed through
The rate pattern precision that it is obtained is higher；Low frequency model is a step more important in inverting, is only established accurately low
Frequency model can just obtain accurate inversion result；Wideband inverting, that is, inverting one kind, this kind of inverting frequency domain relatively
It is carried out under conditions of width, inversion result is more accurate.
Step S52: the lithology of interval of interest is subjected to rock physics cross analysis, impedance decision content is set；
It is magmatic rock that setting impedance value, which is greater than impedance decision content A, and rock physics cross analysis is i.e. to lithology each in reservoir
Rock physical analysis is carried out, this technology is specified magmatic rock impedance value and be greater than compared with mature technology to be existing by Rock physical analysis
15000。
Step S53: it on the basis of inverting data volume, is tracked using the Geobody body in Petrel, will be greater than impedance and sentence
The subtrace of definite value A comes out to arrive the distribution of magmatic rock；
Petrel software is the popular software of geophysics geological reservoir at this stage, and the tracking of Geobody body is Petrel
The mature technology module of body is tracked in software.Only it needs to be determined that seed point, in this embodiment, seed point determine that value is
15000, the part that the value is greater than in invertomer is all tracked out, as the range of magmatic rock.
Step S6: target area structure interpretation mode is established, as shown in Figure 8.
In conclusion the present invention carries out tectonic setting analysis, tectonic setting analysis to the interval of interest of target area first
Two parts are analyzed including tectonic movement analysis and tectonic style, is analyzed by tectonic movement, specifies that interval of interest is in rift valley
Phase, then tectonic style analysis is carried out to rift, tectonic style analysis includes being divided into rift development, disconnected col conversion development and down warping region
In three stage of phase, wherein Fault-subsidence Stage mature fault, that is, correspond to interval of interest reservoir bottom mature fault, and break col conversion and Depression Stage tomography
Gradually agensis is analyzed by tectonic style, to the seismic response features of typical earthquake profile analysis reef flat facies, establishes reef
The identification plate and sedimentary origin mode of beach phase；Finally on the basis of clear magmatic rock type, analysis magmatic rock seismic facies is special
