Research Interest

1, natural gas hydrate identification and resource parameter estimation. Based on the experimental results of rock physics and the theory of fluctuation, the BSR identification marks and physical properties (longitudinal, shear wave velocity, density, Poisson 's ratio) are combined to reflect the results of the forward calculation and drilling results. Hydrate. According to the theory of thermoelasticity, the relationship between seismic velocity and thermoelasticity parameter is established, and the saturation of hydrate and free gas is estimated from velocity information. Considering the influence of thermodynamic parameters on seismic velocity, the accuracy of saturation estimation is improved. Especially in the case of high saturation, the estimation of free gas saturation is very important. 2, metal mine seismic data acquisition, imaging and interpretation of the results of technology research. The surface and deep seismic geologic conditions of metal ore exploration are very complicated, and the assumption of conventional reflection seismic exploration technology for geological structure is not established. Conventional reflective seismic exploration technology can not achieve good exploration results. Therefore, the imaging and interpretation of metal mine seismic exploration are facing new problems. Based on the theory of seismic wave scattering, the data acquisition, imaging and interpretation techniques of metal mine seismic exploration are studied. 3, three-dimensional observation system design. Design concept: from the key imaging technology for seismic data requirements of the design of three-dimensional observation system. 4, high - resolution seismic exploration technology.
