据统计，我国大、中型气田数量只占２０８，储量却占８３４４，特别是大型气田只占总数的４３，储量却占５０３５。大、中型气田又以砂岩气田和碳酸盐岩气田占绝对优势，总储量占９９６５，与世界趋势一致，这就决定了我国天然气的勘查始终应以大、中型砂岩气田与碳酸盐岩气田为追寻目标。储层的构造古地理分布对勘探具指导意义，可分为四区：中部克拉通盆地区；西部复合盆地区；东南陆缘断坳盆地区；东部裂谷盆地区。并分别对应于气区、含油气区、富气油区、含气油区。据此，今后的勘探战略应是加强中部、发展西部，重视海域、加深东部。
According to statistics, only 20.8% of China’s large and medium-sized gas fields have reserves of 83.44%. Especially large-scale gas fields only account for 4.3% of the total and 50.3% of reserves. Large and medium-sized gas fields are dominated by sandstone gas fields and carbonate gas fields, accounting for 99.65% of the total reserves, consistent with the trend of the world. This determines that exploration of natural gas in our country should always be conducted with large and medium-sized sandstone gas fields and carbonates Rock gas field for the pursuit of goals. The tectonic palaeogeographic distribution of the reservoir is instructive for exploration. It can be divided into four areas: the central craton basin, the western composite basin area, the southeast continental margin depression basin and the eastern rift basin area. And correspond to the gas zone, oil-bearing zone, gas-rich zone, gas-bearing zone. Accordingly, the future exploration strategy should be to strengthen the central region, develop the western region, attach importance to the sea area and deepen the eastern region.
