Study on Calculation Method of Formation Pressure Using Well Logging Data

Abstract

Formation pressure Changes is the main reason for casing damage. In order to clearly know formation pressure,taking Sabei area of Daqing oilfield for example,On the basis of researching the relation between Formation pressure and logging data,By studying the relation between test data of ninety-three small stratum pressure and well-logging data with logging unit of water-out interval logging series of nine RFT test well, with statistical regression we come into being a theory model making use of water-flooded zone log reading to calculate formation pressure quantificationally .To improve the calculation accuracy of the formation pressure using logging data.
