2、 December, 1976 whose tutor was Professor He Zhenhua. He graduated from Chengdu University of Technology in Earth Exploration and Information Techniques major and was granted the Master Degree in June, 2010. Abstract Sei

3、smic rock physics is a emergent techmology used to identify the reservoir lithology and general geology, link rock physics and seismic exploration, emerging technologies, quantitative describe the relationship between th

4、e rock , oil and gas. Experimental measurements of core and conduct seismic rock physics, understanding of rock structures and the relationship between seismic velocity, seismic wave propagation characteristics and under

5、standing of the reservoir parameters of the physical links to improve reservoir lithology parameters on the seismic wave field effect understanding of the seismic interpretation determine lithology, identification of oil

6、-water layer, determine the theoretical foundation rock interface.Carbonate is the important exploration targets of increasing the oil and gas reserves in current,therefore, the study of carbonate rock physics and reserv

7、oir identification is necessary. This article has taken the carbonate rocks as the main object of study, carried out the following researches, and obtained the important understanding: First, it introduced the system of

8、taking samples of carbonate rocks, MTS rock physical test system and the basic principles of rock properties and acoustic parameters of the measurement method. Physical properties of rock and acoustic parameters of the t
