Abstract: Ordos Basin is rich in various types of natural gas resources. With the deep exploration from conventional to unconventional hydrocarbons and from shallow to deep strata, a set of natural gas reservoirs of new fields and new types are discovered in Ordos Basin. Based on exploration achievements in recent years, the paper summarizes the new types of gas reservoirs, including deep coalbed methane, Taiyuan Formation limestone gas and bauxite gas, Ordovician presalt gas, marine shale gas, and deep Proterozoic gas, and further performs an in-depth analysis from the perspectives of sedimentary-tectonic background, source-reservoir configuration, and sealing-preservation condition. By analyzing the deployment relationship of source-reservoir-cap assemblage and summarizing the differences of accumulation characteristics and various natural gas, it is believed that these gas reservoirs generally have the accumulation model of near-source, self-generation and self-reservoiring. Based on determining the enrichment characteristics of gas reservoirs, the paper evaluates the favorable exploration areas for natural gas reservoirs in various fields and clarifies their resource potentials and reserve scales. The favorable gas-bearing area of deep coal bed methane is 6.9×10⁴km²; the resources are estimated to be 13.80×10¹²m³, expected to achieve a reserve of trillions of cubic meters. The favorable gas bearing area of Taiyuan Formation limestone gas reservoir is 1.5×10⁴km², with preliminary estimated resources of 1.6×10¹²m³, and a reserve scale of 5 000×10⁸m³. The exploration area of Taiyuan Formation bauxite is 7 000 km², with natural gas resources exceeding 5 000×10⁸m³. The favorable exploration area for presalt natural gas in the Member 4 of Ordovician Majiagou Formation is 2.5×10⁴km², with an estimated reserve exceeding 7 000×10⁸m³. The favorable gas-bearing area of Wulalik Formation marine shale is 9 000 km²; the natural gas resources are estimated to be 1×10¹²m³, and two gas abundance zones have been identified. Two favorable areas of natural gas in the deep Proterozoic are optimized, with an exploration area of 5.71×10⁴km². The natural gas resources in Ordos Basin still have large exploration potential.
