南海北部陆缘合浦盆地低熟油气/生物气成藏条件及勘探前景

Reservoir Geological Conditions and Exploration Prospects of Low Mature Oil and Gas/Bio-gas in Hepu Basin,Guangxi

重点分析研究合浦盆地低熟烃源岩有机质丰度、生源母质类型和成熟度等生烃条件,以及生储盖组合、圈闭类型和油气运移和保存等油气成藏地质条件,认为合浦盆地具有形成低熟油气/生物气的有利地质条件,是华南陆块西南缘上具有一定油气勘探远景的沉积盆地。合浦盆地未来油气勘探方向及重点勘探领域,应围绕低熟烃源供给区,主要勘探寻找低熟油气及浅层生物气资源,争取获得油气勘探的突破。

This paper discussed the amount, type, and maturity of low mature source rocks as well as the conditions of source-reservoir-caprock association, trap, and hydrocarbon migration and preservation in Hepu Basin. The results indicate that the Hepu Basin is a sedimentary basin of great hydrocarbon potential in the continental block of south China, with good reservoir geological conditions of low mature oil and gas/ Bio-gas and processes of their formation, mobility and accumulation. The exploration direction of low ma- ture oil and gas/bio gas resources in Hepu Basin was suggested.
