浅层气指埋深小于１５００ｍ的各类天然气资源，主要包括生物气、油型气、煤成气、水溶气等。我国的浅层天然气资源主要分布在南方沿海小型中新生代盆地，东、西部含油气盆地及主要含煤盆地。气藏类型分为３种：原生超浅层微气藏、近源浅层小气藏和浅埋常规气藏。其开发特点是：压力低、产量小、开采工艺简单、投资规模小。
Shallow gas refers to all kinds of natural gas resources whose burial depth is less than 1500m, including biogas, oil gas, coal gas and water-soluble gas. The shallow natural gas resources in China are mainly distributed in the small Mesozoic-Cenozoic basins along the southern coast, the petroliferous basins in the east and west and the major coal-bearing basins. The types of gas reservoirs are divided into three types: primary ultra-shallow micro-gas reservoir, near source shallow gas reservoir and shallow-buried conventional gas reservoir. Its development features are: low pressure, small output, mining technology is simple, small-scale investment.
