摘要
Pelagian basin in North Africa is one of Meso-Cenozoic oil-gas bearing basins,which developed reservoir form Jurassic Jerba Group to Miocene Tazerka Group,but the lower Eocene Nummulite limestone is the main reservoir.From now on the oil discoveries of nummulitic limestone in Libya have been about 80% of the total reserves.It had been trilled two failed wells in the high part of the structure because of the lack of nummulitic limestone.Based on the method of forward model,inversion and seismic attribute extraction,the limestone reservoirs of the Metlaoui Group is identified in this paper.The distribution of possible nummulitic limestone reservoir rocks is also predicted in this paper,combined with the study of geology,paleogeomorphic,drilling and logging data.
