Abstract:

Based on the accurate description of point bar, the researches on improving the accuracy of geological structural model, lithology model and modeling method of lateral accretion interbed in point bar are carried out. A geological modeling for horizontal well in point bar is proposed. The application of this method shows that the error of
structural model is within 0.45 metres and the coincidence rate of the lateral accretion interbed is 85%. It is favorable for guiding the design of the horizontal well.

Key words: type log, porosity, shale content, SP reduction factor, apparent resistivity
