Seismic Reservoir Prediction in Lengjia-Leijia Area

Abstract:

Through the deep exploration in Lengjia-Leijia area, four reservoirs were found: the lower sub-section of the third member of Shahejie formation, the fourth member of Shahejie formation, Mesozoic, and Archean. The fourth member of Shahejie formation and the layer below it had fewer drilling reach; its reservoir stratums are different. Seismic reservoir prediction has become the major means of oil-gas reservoir evaluation. The logging-constrained inversion method was applied in this study. A geologic model was established based on the detailed interpretation of seismic data; then, inversion and prediction were performed to describe and evaluate the distribution, thickness, and physical characteristics of the reservoirs. The results showed that the reservoir in the fourth member of Shahejie formation, Mesozoic, and Archean are well developed, and that oil-gas accumulation is in good condition. Therefore, the deep layer in this area is an important exploration direction. This study also provided the preliminary prediction that a favorable trap area exists.
