Abstract:On gas reservoir evaluation, in a cased well logging reservoir evaluation, Previous well logging analysis procedure is the use of resistivity and porosity by skeleton, pore fluid and mud resistivity such as parallel model, According to the variety of water saturation calculation formula, the derived formation water saturation, thereby determining the formation fluid properties, so as to make the evaluation of formation. The program cannot use existing data to draw a correct conclusion. Based on the mineral composition and pore fluid with different compression, especially the different fluid compressibility coefficient difference; As well as on acoustic logging data compression coefficient model undertakes research, compiled well logging analysis program ( CFI ), this procedure in the existing conventional data, the reservoir of the gas can accurately identify. This procedure in Dagang oilfield application obtained very good effect.
