Research On The Drawing Method Of Analysis Diagram Of Fault Seal

Fault sealing is an important means to analyze the content of geological reservoir.With the researchers continuous exploration to the fault sealing,a variety of new analysis methods have emerged,which have gradually made the current fault sealing analysis software fail to gratify requirement of domestic evaluation,and cannot paint visual analysis diagrams for the new published sealing algorithms.In 3D drawing,the accuracy of projection also affects the drawing of analysis results.Therefore,combining with new evaluation methods and improving the accuracy of projection are of great significance to the analysis of fault sealing.Aiming at the issue faced by the fault sealing analysis software and newly published evaluation contents,the two drawing methods of plane analysis diagram and spatial projection algorithm are studied.The main content of the research about this thesis is summarized as follows:1.In the painting process of plane analysis diagram,through the analysis for the study of lithologic butt-sealing theories and the lithologic butt-sealing rules,a tree-structural determining method for lithologic butt-sealing is established,and the hierarchical generation technique based on compound grid is put forward,utilized this technique to form a set of plane painting system mainly based on the analysis for double wells stripe skip fault sealing.2.In the drawing of spatial projection,the projection method based on TIN-Octree mixed model is established and the projection of spatial well location attribute onto fault layer is achieved,by the utilization of existed stratum models and fault models.And the drawing of spatial fault sealing analysis diagram is accomplish,by utilizing post-projection results and combinationing with the calculation rules of domestic applicable new sealing evaluation algorithms.3.Basing on the drawing of plane analysis diagram and the projection of spatial attributes,and combining with the newly published new evaluation algorithm and evaluation methods,the thesis provided a visual application system for the geological analysis,which supplies master options for variable parameters and a brief of operating process.The instance test to the results of final drawing is conducted.
