阜阳地区油气资源潜力评价

查明油气资源分布并对其潜力进行预测是为勘探开发奠定基础。本文借助Trinity软件,对阜阳地区颜集凹陷、倪丘集凹陷以及古城凸起进行盆地热史模拟、生烃动力学模拟、储层模拟、盖层模拟、断裂模拟,得到油柱高度、烃源岩厚度、总有机碳含量、烃源岩氢指数等参数,应用烃类生成化学动力学、烃类运移和聚集流体动力学原理对该区油气资源潜力进行模拟计算,结果表明:颜集凹陷生油气强度最大,总生油量达到12.84×108t,总生气量达到144824×108 m3,是阜阳地区资源丰度最高的凹陷。倪秋集凹陷总生油量为6.87×108t,总生气量为84061×108 m3,具备较大的勘探潜力。

PROSPECTIVE EVALUATION OF HYDROCARBON IN FUYANG AREA

Ascertainment of distribution of hydrocarbon and potential prediction of them is the base of exploration and development.The research area is Fuyang including Yanji depression,Niqiu depression and Gucheng depression.Trinity is used to simulate geothermal history of sediment basins,hydrocarbon dynamics,reservoir,cap rock and fracture with oil column height,source rock thickness,TOC,hydrogen index of source rock,etc.Hydrocarbon resource potential of this area is simulated with the application of Chemical kinetics of hydrocarbon generation,principle of fluid dynamics on hydrocarbon migration and aggregation.Results show that Yanji depression has the biggest intensity of producing oil and gas,total oil production reached 12.84× 10^8 t,total gas production reached 144824×10^8 m^3,which has the highest resource abundance in Fuyang area.Total oil production reached 6.87×10^8t,total gas production reached 84061×10^8 m^3 in Niqiu depression,which has great exploring potential.
