摘要
南海北部边缘莺—琼盆地及珠江口盆地白云凹陷天然气资源丰富,天然气成因类型多,是一个具有多种勘探领域和颇大资源潜力的大气区。由于勘探及研究程度尚低,在该区浅层及中深层勘探中所发现的天然气藏多以成熟—高成熟的热成因腐殖型气(煤型气)为主,但也发现了一些生物气及亚生物气(生物—低熟过渡带气)气藏且具较高的产量和一定的储量规模、资源潜力及勘探前景广阔。认为这是一个非常值得重视与关注的天然气勘探新领域,只要加大勘探投入力度和天然气地质综合研究的深度。
Yingqiong basin and Baiyun sag of Pearl River Mouth basin are rich in gas resources and diverse in gas origin, with varied exploration fields and greater resources base. So far, biogenic and biogenic-undernatured transition gas have been discovered in the basin, besides shallow and mid-deep gas reservoirs predominated by matured and high-matured humic gas(coal-formed gas).With sizable reserves and higher production capacity, these biogenic and biogenic-undernatured transition gas have a great resources base and exploration potential. A breakthrough of biogenic gas exploration in this area is just round the corner providing that prospecting strength and comprehensive research depth are enlarged.
