摘　　要：对济阳坳陷浅层天然气地球化学特征进行分析,并结合气藏地质背景研究,在414个浅层气藏中识别出生物气藏201个,并应用分形法和翁氏旋回法预测了济阳坳陷生物气资源量。经预测发现,在下一勘探阶段济阳坳陷最可能发现数量多但规模小的生物气藏,应用分形方法预测生物气总资源量介于231.75×108~463.49×108m3之间,应用翁氏旋回法预测济阳坳陷生物气资源量约556.44×108m3,待发现生物气资源量为401.68×108m3。此结论对研究区生物气勘探具有十分重要的意义。The shallow natural gas in the Jiyang depression has been analyzed for geochemical characteristics in conjunction with geological setting.Among the 414 shallow gas reservoirs,201 biogenic gas reservoirs are identified.The biogenic gas resources in the Jiyang depression is predicted with fractal and Weng's life cycle methods.It is predicted that a large number of small scale biogenic gas reservoirs are likely to be discovered in the next exploration stage in the depression.The biogenic gas resources is predicted between 231.75×108-463.49×108m3 by fractal method,556.44×108m3 by Weng's life cycle method,and the undiscovered biogas resources are about 401.68×108m3 by Weng's method.This result is of very important significance to biogas exploration in the study area.
