“八五”以来，随着一批大中型气田的发现，我国天然气储量迅速增长，天然气勘探形势呈现良好的势头。下世纪初我国陆上天然气勘探领域“八五”以来，我国天然气储量增长的地区主要集中在中部和西部，且尤以大中型气田的储量占优势。从天然气的资源量分布来看，其绝大部分也集 Since the Eighth Five-Year Plan, with the discovery of a batch of large and medium-sized gas fields, the reserves of natural gas in our country have been rapidly increasing, and the situation of natural gas exploration has shown a good momentum. Since the “Eighth Five-Year Plan” for onshore natural gas exploration in China at the beginning of the next century, the areas where China’s natural gas reserves have increased are mainly concentrated in the central and western regions, and the reserves of large and medium-sized gas fields in particular occupy a dominant position. From the distribution of natural gas resources, most of them also set
