Abstract


Through the detailed investigation of the complex geological conditions of coal measures strata and a lot of acoustic testing of coal, different petrophysical parameters are got, making use of the similar theoretical design, the coal physical model of complicated geological conditions is made according to the simulation materials, ultrasonic testing of seismic physical model is conducted to get seismic acquisition data of different observation system and the post stack and pre-stack processing of the seismic acquisition data is conducted. Making use of geological structure of thin seam, fracture zones, holes with different fillings of physical model, seismic response characteristics of the complex geological conditions are analysed and studied, the sensitive attributes of the different geological phenomena are extracted, and analysis of attributes is conducted, correlation and index system of seismic data and attribute property are established, quantitative discrimination of the typical geological structure is achieved. Based on seismic physical simulation technology, it can use the technology to guide practical seismic exploration in the wild, and be able to verify the technical feasibility, practicality and effectiveness of the actual detection of the wild.
