摘要
简述了我国油气资源的分布情况。我国油气资源集中分布在少数大型沉积盆地中；石油资源主要分布于中、新生界，约占87％，天然气资源主要分布于古生界，约占51％；高原、山地、滩海等复杂地区石油资源量为440亿t，占石油总资源量的47％，指出我国今后油气勘探潜力很大、但难度及成本亦逐渐加大。为更充分反映各种油气藏形成特点，文中根据圈闭成因将油气藏划分为构造油气藏与地层油气藏两大类22亚类。
The paper recounts the distribution of oil and gas resource in China. It distributed centrally in a few large scale sedimentary basin. The oil resource which formed in Mesozoic and Cenozozic erathem accounts for about 87 percent. The gas resource mainly formed in Palaeozoice accounts for about 51 percent. The oil resource extent in complex regions such as palteau,hilly area and beach is 44 billion tons accounts for 47 percent of the total resource extent. It points out that the oil and gas exploration potentiality is great in future, but the difficulty and exploration expenditures increased gradually,too. According to the origin of grap,the oil & gas reservoirs are diveded into two large types (structural reservoir and stratigraphic reservoir) and 22 subtypes.
