Research On 3D Geological Modeling Automatic Layering And Cutting Method Based On Mud-logging Data

Oil is important. All countries attach great importance to oil exploitation. They want to accurately measure the geological structure and efficiently mined more oil. Therefore, precise analysis of geological structure is very necessary. Analyzing the formation of different substances to understand this geological structure plays an important role on future energy exploration. Fast automated tiring and arbitrary sectioning are the two main features of the 3D geological modeling, which can be rapidly, intuitively and completely show geological structure to the staff. So 3D geological modeling is an indispensable feature.This article taken from two aspects of 3D geological body, automated tiring and arbitrary sectioning, to study based on logging data involved in the 3D geological modeling algorithms. The main contents and research results include the following aspects:Study automated tiring and arbitrary sectioning of 3D geological modeling. Compared with previous methods analyze their application conditions, advantages and disadvantages.Study automated tiring algorithm of 3D geological modeling. Without losing accuracy of existing methods, we improving operation speed to increase stratification. Based on mud-logging data points modeling, this paper proposes neighbor hierarchical clustering algorithm. In the laboratory project data on the basis of this algorithm to analyze the advantages and disadvantages.Study arbitrary cut algorithm of 3D geological modeling. Also this paper put forward 3D geologic body parallel lines cutting method. Parallel lines cutting method is used to cut 3D geologic body automated tiring facial model. Through the experimental data to analyze the advantages and disadvantages of arbitrary cut algorithm.Based on laboratory logging data, this paper uses neighbor hierarchical clustering algorithm and parallel lines cutting method to achieve related functions of 3Dgeological model.Based on mud-logging data, this paper proposes automated tiring method and arbitrary sectioning method for 3D geological body. These two method enables3D geological body display and analysis functions of mud-logging data. The modeling in this paper will be faster and more accurate. As a result, the 3Dmud-logging integrated system realizes corresponding function and it will be more suitable for laboratory logging data.
