[Abstract]:Because of the complex geological conditions, many drilling data are imprecise, uncertain and non-numerical. The single dimensional data generated by traditional data analysis is one-sided and isolated, and it is difficult to establish the connection of information between adjacent wells. The comprehensive application of 3D visualization technology based on multi-source information in geological oriented projects can not only provide advanced visual auxiliary means for oilfield production, but also play an important role in the construction of oil field digitization. Based on the analysis of related data at home and abroad, this paper first analyzes the geological oriented information sources of multi-source information, and discusses the preprocessing method of multi-source information to eliminate redundant information. Then, the spatial interpolation method is compared in horizontal and vertical, the cubic spline interpolation method is selected as the method of establishing spatial geometric model, and the engineering and physical parameters involved in geological guidance are calculated. Based on the field data, a geological oriented 3D visualization environment is established, and relevant attributes are extracted along the borehole trajectory. D-S evidence theory is used to modify the model and update the model in real time. Finally, the operation of 3D environment, such as environment rotation, scaling and cutting, and the application of 3D visual environment in geological guidance are discussed. The results show that the 3D visualization environment established in this paper can monitor, adjust and operate the geological guidance process in real time, which plays an active role in guiding drilling in the field.
