Abstract: The well developed fractures in carbonate rocks allow the strata to be of strong anisotropy which causes obvious orientation in seismic wave propagation such as amplitude, travel-time, interval velocity, frequency and absorption, etc. Their variations are closely related to the fractural orientation and density, hence the fractural prediction can be conducted using P-wave orientation characteristics. This paper studies the method for fractural prediction by using orientation and interval travel-time, by which the fracture development situation of carbonate rocks in Tabei-Eastern Lungu area in Tarim basin is predicted and good effectiveness or results are obtained.

Key words: Tabei area, carbonate rock, orientation attribute, prediction, forecast, fractural density, fractural orientation
