An embodiment of the invention discloses a method of adjusting and calibrating a rock density and a speed curve and an apparatus thereof. The method comprises the following steps of based on correlation of a caliper curve or a resistivity curve with a first attribute curve in a same depth segment, combining a matching result of a corresponding synthetic record and near-well seismic channel information so as to determine that a hole enlargement influence which is generated by hole enlargement of a hole diameter on the first attribute curve to be a first influence or determine that the hole enlargement influence which is generated by hole enlargement of the hole diameter on the first attribute curve to be a second influence, wherein the first attribute curve includes a density curve and/or a speed curve; if the influence is the first influence, using a first adjustment and calibration mode corresponding to the first influence to adjust and calibrate the first attribute curve; and if the influence is the second influence, using a second adjustment and calibration mode corresponding to the second influence to adjust and calibrate the first attribute curve. By using the method of adjusting and calibrating the rock density and the speed curve and the apparatus thereof, rapid adjustment and calibration to the rock density and the speed curve can be realized.
