Cracks are wide spread existence in the crust.The detection of the cracks and the recognition of oil and gas reservoir is the problem urgent to be solved in hydrocarbon exploration and development recently.For the sake of cracks,the rock can be anisotropic.The rock physics property and the acoustic logging response are different with different cracks in shape and development degree.Based on the Eshelby-Cheng rock physics model and the real axis integration method of the transversely isotropic media,the acoustic logging characteristics of the horizontal crack developed reservoir is researched,and the effect of the crack parameters on acoustic logging is simulated,which provides theoretical basis for the oil and gas exploration using acoustic logging and an effective mean for the inversion of the crack parameters.
