Ordovician carbonate rocks in Tarim Basin are typical karst reservoirs. For the little difference of wave impedance in the formation interface of the carbonate rocks, the reflection information from the Ordovician is obviously poor. The development of karst fracture on the seismic profile displays a string of beads, which is a significant method for identifying karst. According to the characteristics of Tazhong area, we should place stress on the optimization of the relative amplitude preserved processing and denoising method in seismic processing and choose advisable deconvolution technique to improve the resolution of Ordovician. The application of prestack time migration technique is an effective approach to stand out the reflectance signature of Ordovician in Tazhong area.
