Abstract：Predicting the oil and gas potential of heterogeneous thin reservoirs is a difficult part of oil and gas reservoir exploration and development. Due to low resolution, the results of conventional post-stack and prestack inversion methods based on full-stack seismic data fail to fully characterize the lateral changes in reservoirs and their oil and gas potential and thus cannot meet the oil and gas exploration needs. The carbonate oil formations at the top of the Mishrif Formation in the Land and Sea Block 1, the United Arab Emirates are 5~17m thick, and the reservoir is highly heterogeneous. The conventional methods, such as post-stack attribute, post-stack inversion, and prestack inversion, deliver oil and gas detection results that coincide poorly with the drilling results. To solve the above problem, this paper analyzed seismic data from drilling data, logging data, and spectral characte-ristics and selected medium-angle stack data. Then, petrophysical modeling and cross-plot analysis of sensitive parameters were performed to construct the attribute curves of the reservoir fluid as oil and gas sensitive parameters. Finally, waveform indication inversion technology was applied to oil and gas detection, and favorable oil and gas distribution ranges were predicted. The prediction results are in good agreement with the drilling results and the known oil-gas-water distribution range. The proposed method improves the accuracy and reliability of oil and gas detection and can provide technical support for oil and gas exploration.
