METHOD OF WELL PLACEMENT MODELING AND GEOSTEERING

摘要

A method of establishing a geographical model for wellbore involves receiving a geographical model of a wellbore, and receiving measured log data and a trajectory of the wellbore. A simulated tool response is simulated along the trajectory based on the geographical model, and a measured tool response is determined based on the measured log data. A portion of the simulated tool response is found corresponding to a portion of the measured tool response, and the portions are compared to generate another geographical model. A dip angle of the portion of the simulated tool response is changed within a preset window to find a dip angle value.
