I am honored to be here and give you a presentation about our software and technology.
We have 4 parts
We have 4 parts
In RMS software: When a horizon is identified as an Intrusion type in the Horizon Modelling dialog box, a special algorithm is used to create the surface
Feature 4 is Support Various Analysis and Calculations based on the structural model
On one hand ,the structural model is built can accomplish various model -based analysis and computations.
On the other hand ,we can provide the suitable variant model representation for each individual application.
For instance,
The structural restoration based on 3d model , we can get the ancient structural model in any period
And the evolution section
And do the stess calculation
Enable to Display in colors and in 3d vector
We have 4 parts
core
can be embedded in other software system
全工区面积500平方公里，但脉体和裂缝的大小几米宽度和厚度都可以准确描述
According to the paleo-structure modeling get anywhere the balance of the section
multi-users can build or updata any interested sub regions at the same time
You can download a sub region ‘s data
And build the sub model ,
If the region is not be used by others
If the grid of sub model is the same scale ,
The model around the overlap region can be merged seamlessly in the database.
can be used in many fields
And This is one of the applications
We have 4 parts
There are more than 1500 faults
Uausally , we have to do a lot of interactive work to deal with so many faults
it is a tedious and repetitive work
but now ,we have lots of intelligent batch processing functions to built the model quickly.
In that case ,it only costs 20 workdays to complete such a complex structural model by one person
In this model there have 1500 faults including synsedimentary faults , master faults and associated faults controlling the basin.
In addition （moreover）
There are varies of visualization ways , such as making section ,getting layer or get a sub tectonic model .
we can see the accurate description of the geological features ,
And based on the structural model we can get the structural maps and profiles automatically and efficiently
This is a structural profile of inline direction
