He graduated from Chengdu University of Technology in oil-gas field development geology major and was granted the Master Degree in June, 2010. Abstract In the oil and gas reservoir exploration and development of buried hill, as the reservoir heterogeneity is generally more serious, the prediction and description for spatial distribution and change of the reservoir is the key and difficulty of exploration and development. The impact of multistage tectonization of the buried hill reservoir for Lower Paleozoic in Chengbei306-Zhuanghai10 area lead to that buried hill fault system is complex and diverse, the degree of weathering and erosion formation is varying, the scale and form is ever-changing, the spatial distribution of reservoir and fractured-vuggy zone of the favorable hydrocarbon accumulation and migration in the layered reservoir is poor, the horizontal is varying, the heterogeneity and anisotropic is strong, the diversity of the reservoir and flow space is diversity, the cause of multi-stages is complex and so on. These bring great difficulties to the lateral prediction and description of buried hill fractured-vuggy reservoir. So it is necessary to use a new method to further study of horizontal distribution of the reservoir. Firstly, according to the drilling mud logging, well logging, properties and analysis data, the author understood the basic reservoir characteristics of the lithology, pore structure, reservoir properties. We knew the longitudinal characteristics of reservoir by seismic coherence technology. It is a solid foundation of determining the grading standard fo
