Abstract: Feixianguan Formation of lower Triassic is an important reservoir, which mainly consists of the dense oolitic dolomite and limestone altered by the late dolomitization of oolitic bars. Tieshanpo area is located in the northeast edge of Kaijiang-Liangping trough during the Feixianguan Period where is very favorable to form oolitic shoal reservoir. The seismic inversion constrained by geological model and based on theory of information fusion is used in reservoir prediction. Much geosciences information is unify to the same model including geology, well logging, seismic and so on, and is fused organically in model space to increase the information, improve the information matching and confidence. At the same time, the technique of coherent interpretation constrained by geology also made preferable effect in the reservoir prediction of gas, water and their relationship.
