Abstract: Carbonate gas reservoir is a main exploration target for gas in Sichuan basin, but Qixia formation carbonate is neglected. Its fractures and dissolution pores are the major reservoir for gas. A reliable forecast of its fractures and dissolution pores is key to the exploration. This paper, based on logging and seismic data, compares the reservoir waveforms and distribution, uses coherent attributes and preoverlapping anisotropy check to forecast Qixia formation fractures and dissolution pores, and presents exploration targets based on reservoir development model, offering theoretical support for further gas exploration in Qixia formation.

Key words: Sichuan basin, Qixia formation, fractures and dissolution pores, reservoir forecast
