6. Recent Key Exploration Fields and Zones

For the marine carbonate strata in Central Sichuan, the evaluation of key exploration fields and zones is carried out around the mound-beach bodies of Sinian Dengying Formation, granular beaches of Cambrian Longwangmiao-Xixiangchi Formation, granular beaches of Permian Qixia-Maokou Formation, reef beaches of Permian Changxing Formation and Leikoupo Formation of Triassic, and the exploration targets are put forward. In general, Dengying Formation is developed with a low exploration degree, enormous total resources, and broad exploration prospects. The source conditions are well developed for hydrocarbon supply in Qixia-Maokou Formation, not only from the self-developed source rocks, but also from the other source rocks as well. As a result, the Qixia-Maokou Formation is developed with good accumulation conditions, low exploration degree and large exploration potential.
