Abstract：In the interpretation and processing of real logging data,the response pararneters derived from core graduation logging may show their incorrectness.The theoretical methods are offered here which involve the computations of various response parameters of common minerals and fluids. To speak correctly,they are used to •calculate the resistivities of salt water that is mineralized under variable temperature condition; •compute the apparent volume densities of formation frame,pure water,oil,natural gas and salt water whose concentration is known,by using density logging data; •obtain the hydrocarbon contents of formation frame,oil,gas and salt water by introducing the response parameters of neutron logging data; •get the acoustic transit times of formation frame and natural gas(in addition,the corresponding velocities of P-wave and S-wave)by taking the response parameters of acoustic logging data.
