In selecting key parameters,the main genetic method of the oil and gas resource evaluation has some uncertainty,for example,hydrocarbon production rate in the simulation of hydrocarbon,calculation of expulsion rate in the hydrocarbon emission and selection of clustering coefficient in the process of hydrocarbon accumulation.With the improvement of laboratory equipment,simulation results of hydrocarbons rate is more reliable.The hydro-carbon accumulation system is evaluated quantitatively by the quantitative evaluation model based on the analytical hierarchy process.%以成因法为主进行油气资源评价的过程中,一些关键参数选取具有不确定性,如生烃中的烃产率模拟、排烃中的排烃系数计算和油气聚集过程中聚集系数的选取等。随着实验设备水平的提高,烃产率实验模拟结果愈加可靠,应该采用生烃潜力法或压实排烃理论研究排烃系数。选取聚集系数则采用回归分析法,建立运聚系数与地质参数之间的统计关系,并通过层次分析法建立油气运聚单元定量评价结构模型。
