RESOURCES BASE AND EXPLORATION POTENTIAL OF BIOGENIC AND SUB-BIOGENIC GAS IN MARGINAL BASIN OF THE NORTHERN SOUTH CHINA SEA
南海北部边缘盆地生物气和亚生物气资源潜力与勘探前景分析

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.
