Abstract Mineral composition，microstructure，temperature and confining pressure condition of rocks are crucial factors for determining the P-wave velocity of rocks. 49 kinds of rocks are chosen from the carbonate and sand-shale formations of the important exploration area in northeast region of Sichuan Province. The P-wave velocity is determined under the conditions of room temperature and no confining pressure，room temperature and confining pressure，high temperature and confining pressure. The distribution characteristics and influential factors of P-wave velocity for the rocks in northeast region of Sichuan Province are systematically analyzed. The average values and variation ranges of P-wave velocity for sand-shale formation and carbonate formation are given. Many mathematical models are used to determine the relationship of buried-depth and density with P-wave velocity for sand-shale formation，carbonate formation and whole formation respectively. The optimal regression equation is determined. The main influential factors of P-wave velocity are discussed for sand-shale formation and carbonate formation. The qualitative and quantitative relationships of temperature，confining pressure and formation with P-wave velocity are established；and the primary mechanism is discussed simply. After a comprehensive analysis，it can be realized that the deposition of sand-shale formations is continuous. The microstructure of carbonate formation is complicated and it plays an important role in acoustic response.

Key words： rock mechanics northeast region of Sichuan Province P-wave velocity sand-shale carbonate rock
