Research Of Automatic Identification And Calculate Of Oil Layer Pore Pressure

Formation pore pressure method research is what geologic worker and engineer care about for adjust well water flooded of sandstone oilfield. The forecast of adjust well pore pressure is tough and the result affect the well cement job quality, production, etc.DaQing oilfield is big continental sedimentation, early stage water-flood and multiply formation field. Because the heterogeneity be in longitudinal and horizontal, high pressure , normal pressure and negative pressure zone is simultaneity in well that is multi-pressure system. The system can effect well cementation quality and is major reason of casing failure. So pore pressure forecast accurate has very important meaning for field production.This paper analyze relation of pore pressure and well logs, research and master pros and cons of all pressure detection methods. We find result of old method is dissatisfaction, so we find out a new way use well log to get pore pressure, and build explain model.
