Research On Vectorization Geologic Map And Modeling Geologic Structure Technology

Geological map is an important source for researchers, and many research results are shown by graphic. It is especially important to enhance accuracy and recycling of the geological map. Vectorization is ultimately to replace manual paper-graphics technology. The technology addressed by the vectors in the accuracy, ease of modification, and other operational aspects of a raster map has great advantages. The vectorization technology is a important tool in geological prospecting development research item.The essential of modeling geological structure is, using analysis of the original data, establish a model of three-dimensional graphics reservoir which is able to make reservoir model and stratigraphic framework layered solid model. This model indicates the relationship between the geologic structure as well as each structure relations. Moreover, according to the statistical difference and the model of simulation, establishes the reservoir physical property model, thus in the research oil gas pool development's uncertainty and the investment risk, provide the data for dynamic simulation of the oil gas pool's and the policy-making basis for the development.This paper vectorization technology which involves in the development geologic interpretation platform system process, as well as in the geologic structure modelling uses the grid distortion technology has conducted the thorough research.Firstly, introduced vector technology to the basic principle of common vectorization processing methods and geological interpretation platform with a few typical examples are discussed. Implementation of the feature vectorization of the border region, and the dichotomy step-length of the new algorithm applied to well logs on vectorization, and achieved good results.Secondly, Deeply studying which based on the grid tectonic deformation modeling methods, realized had the direction and the non-direction fault restraint grid algorithm. Finally take VC++6.0 as the tool, builds a geologic interpretation platform initially the system prototype, has realized in the geologic structure modelling partial functional module.
