Abstract
The invention relates to the technical field of oilfield exploration and development, and particularly relates to a method for characterizing the rock physical characteristics of deeply buried carbonate rocks, comprising the following steps: determining a rock type of a rock thin section by identifying the surface structure characteristics of the rock thin section corresponding to a core plunger sample; performing a normal pressure nuclear magnetic resonance test and rock physical characteristic tests on the core plunger sample; establishing an identification plate, a first relation, a second relation and a third relation; characterizing the rock physical characteristics of a target rock sample under normal pressure and its buried depth according to the normal pressure nuclear magnetic resonance test result and the overburden pressure nuclear magnetic resonance test result of the target rock sample respectively.
