The present invention proposes a method and apparatus of determining stiffness coefficients of formation, wherein the method comprising: setting up a relation of stiffness coefficients of formation Cand C, C, Cbased on stiffness coefficients of a formation core sample; computing clay content of formation along depth continuously based on formation logging information; computing the stiffness coefficient of formation Calong depth continuously based on a P-wave velocity and a volume density of the formation; computing the stiffness coefficient of formation Calong depth continuously based on a S-wave velocity and a volume density of the formation; and then computing the stiffness coefficients of formation Cand Calong depth continuously based on the calculations above, the relation of stiffness coefficients of formation Cand C, C, C, and a relation of an anisotropy coefficient of the P-wave of the formation and its clay content or a relation of an anisotropy coefficient of the S-wave of the formation and its clay content. The present invention does not need to calculate stiffness coefficients by using a horizontal S-wave velocity inversed from the extracted stoneley waves, and avoids an extraction process of horizontal S-wave, such that the calculation is simple and effective.
