Abstract: Fornation oil volume factor calculated with conventional method has bigger error is imreasonable because oil compressional factor is regarded as constant. In fact, oil compressional factor is in inverse proportion to fornation pressure, so we derived an accuracy formula for calculating formation oil volume factor by adopting equivalent compressional factor, and provided case history with it.

Key words: Crude volume factor, Oil compressibility, Calculation, Example
