Abstract Using ordinary seismic attributes like MSR (meansquireroot) amplitude to predict the carbonate reservoir where the fractures and caverns are major reserve space is more mature prediction technique of carbonate reservoir,but there has been not a set of relevant mature prediction technique uptonow for the carbonate reservoir where the matrix pores are major reserve space. Taking the D oilfield in Oman basin of the Middle East as an example,the paper introduced the lithologic electric nature of matrix porous carbonate reservoir and distribution character of favorable lithofacies;presented that only the approach using multitools comprehensively to carry out reservoir prediction can improve in maximum the confidence level of predicted results;and further summarized the seismic prediction approach of carbonate reservoir mainly taking matrix pores as reserve space,achieved good application results. The concrete studied ideas are:determination of objective intervals based on logging data;creating development mode of objective reservoir;using seismic attributes technique and inversion to analyze and study the reservoir;discovery and determination of traps in combination with geologic and logging data,which carries out comprehensive evaluation and guides the drilling deployment.
