摘要： A method is provided for generating an invertible 3D hydrodynamic earth model suitable for defining target characteristics of a subsurface area formed by a plurality of formations and comprising drilling positions of potential and real wells. The method comprises constructing an initial 3D earth model by combining solutions for a set of single 1D models, each of the models corresponding to a real or potential well drilling position and covering the entire respective aggregate of formations along the wellbore, with solutions for a relevant set of 2D earth models which are constructed only for single formations, and optimizing the constructed initial 3D earth model by defining an optimal set of formations and an optimal set of calibratable model parameters. A method and system are also provided for application of the earth model construction method for predicting overpressure evolution before and during drilling. As the earth model constructed in accordance with the above method provides efficient inversion of data, in particular gathered while drilling, the prediction can be updated in real-time while drilling. The invention can ensure optimization of the drilling process and improves its safety.
