DGB OpendTect Commercial v4.2.0k 英文正式版(地震目標檢測系統軟軟體)
check crack\install.txt
OpendTect軟體是荷蘭dGB公司研發的一個地震目標檢測系統，集層序地層解釋系統、傾角導向、
地震顏色反演等功能為一體，可同時對多個地震屬性體進行處理、可視化和解釋。其中最具特色
的技術是傾角導向和層序地層解釋系統。
該軟體利用傾角導向可直接生成導向體，導向體包含空間每一個采樣點的傾角和方位角資訊
，在多道屬性處理及濾波時利用導向體來充分考慮地質目標體的空間展佈，從而提高目標體及斷
裂檢測的精度。
此外，運用傾角導向功能還可自動追蹤年代地層事件，進而進行沉積體系域解釋，幫助研究
人員更直觀、更深刻地理解地層沉積演化過程。
OpendTect is an open source seismic interpretation software
system for processing, visualizing and interpreting
multi-volume seismic data, and for fast-track development of
innovative interpretation
tools.
Optionally OpendTect can be extended with (closed source)
commercial plugins.
2D, 3D, 4D
and Prestack Seismic
Analyze 2D, 3D, 4D pre- and post-stack seismic data.
2D and 3D Viewers
Data processing and visualization are rigorously integrated in
the OpendTect system. Visualization elements can be moved
freely through data space to interactively analyze data from
stored volumes, or data that are calculated on-the-fly.
Volume Rendering
and Stereo Viewing
Volume-rendering, stereo viewing and color blending are
supported features.
Seismic Attributes
Numerous attributes and filters, math and logic, attributes
from attributes are supported in the industry's most powerful
attribute engine.
Spectral Decomposition
Spectral Decomposition is used for imaging and mapping tempora
bed thickness and geological discontinuities. Algorithms
include FFT and CWT.
Movie-Style Parameter Testing
Attribute parameters (frequency, time gate or step out) can be
inspected in a movie-style way, to quickly find the optimal
settings for your data.
Distributed Computing
Heavy processing of large volumes can be carried out in batch
mode on multiple machines and on multiple platforms that can b
accessed through the network.
Interpreters can share surveys.
Horizon Tracking
The updated horizon tracker has more user-friendly editing
capabilities and is more robust due to the new step-wise
tracker functionality.
Faults
Fault planes and fault-sticks sets.
Well-Tie
The synthetic to seismic well-tie module enables the
interpreter to tie wells to seismic.
-Synthetic seismogram
-Check-shot correction
-Additional stretch and squeeze
-Updated depth/time model
-Statistical wavelet extraction
-Deterministic wavelet extraction
Time to Depth conversion
Use an existing velocity model, or create one with the new
Volume Builder.
Supports: on-the-fly TD conversion of display elements and
batch processing of volumes.
Geobodies
Insert an iso-surface in a volume rendered cube and save it as
a geobody.
Manually draw 3D bodies.
Madagascar Processing
OpendTect has a generic user interface to Madagascar, the
open-source software package for geophysical data processing
and reproducible numerical experiments.
GMT Mapping
Via the link to the open-source GMT package you can create
within the OpendTect UI scaled maps of OpendTect results.
GapDecon
A multiple removal tool through prediction error filtering.
Auto-loaded in OpendTect base. (Sponsored by Addax)
HorizonAttrib
The Horizon attribute allows surface (horizon) data to be
combined with cube data for calculations. Auto-loaded in
OpendTect base.
Annotations
Annotate seismic data with text-boxes, hyperlinks, (lap-out)
arrows, and images. Auto-loaded in OpendTect base. (Developed
as part of OpendTect SSIS; sponsored by Shell, BG-group,
Statoil, TNO)
MatchDelta
Trace cross-equalization functionality that is used to correct
small misalignments in 3D seismic volumes prior to further
analysis. It is typically used to align time-lapse seismic
data, multi-azimuth stacks or angle stacks (Residual NMO
correction). Auto-loaded in OpendTect base.
