水平井高精度三维地质建模技术及应用
High Precision Three-dimensional Geological Model and Its Application in the Interpretation of Horizontal Well
摘要
Abstract
The traditional interpretation method of horizontal well use adjacent vertical wells stratigraphic correlation projection for the horizontal well trajectory main direction and picks up the key formation interface point trajectory and formation,but because of the formation structure changes,this method has some limitations.Based on the comparison of sand bodies around horizontal wells,the high precision three-dimensional geological model is established by the nearest neighbor algorithm of full section restriction.To find out the relationship between well trajectory and formation space, and improve the accuracy of horizontal well logging interpretation,the sand mass along the horizontal well trajectory is extracted in the model combined with horizontal well logging curves, so the visual representation and fine characterization of the horizontal well trajectory and formation space are realized by human-computer interaction.The method removes the shortcomings of traditional geological modeling and improves the accuracy of sand body prediction in horizontal well trajectory.关键词
