In this paper, the mudstone acoustic time difference method and the vitrinite reflectance method are used to calculate the Lower Cretaceous denuded thickness in the Santanghu basin.

In this paper,we calculate the erosion amount of Tertiary-Cretaceous in Sanjiang Basin by mudstone and total acoustic time difference method and vitrinite reflectance method.

As propagation velocity of acoustic wave in rocks is closely related with rock properties, porosity and properties of fluids in pores, acoustic travel time anomaly in fault rock can be used to determine the dynamic properties of faults.

By using the acoustic travel time(AC) data,other test data and variable scale fractal techniques,the distribution of natural fractures in Chang 4+521-2 reservoirs of Yuan 48 wellblock in Tiebiancheng oilfield was predicted,and the relationship between the fracture development degree and initial deliverability of oil wells was also discussed.

A method for deriving rock diffusion coefficient from acoustic interval transit times;

Estimation of comprehensive gas diffusion coefficient of a sandstone and mudstone combination bv acoustic interval transit time.;

Nonlinear mapping between the characteristic parameters of borehole side seismic trace and acoustic interval transit times is made by using neural network, then acoustic logging curve under borehole bottom may be obtained through extrapolation to predict formation pressure under borehole bottom by using seismic and logging data.
