Abstract

Abstract: Three key problems are encountered when applying the quantitative analysis technology of the whole petroleum system to evaluate oil-gas resource by genetic method. One is how to input the thickness, total organic carbon (TOC) and hydrogen index (HI) of representative source rocks and the corresponding hydrocarbon generation kinetics model during the grid calculation. Another is how to establish and select reasonable parameters of hydrocarbon generation kinetics model of the source rock. The third is how to reasonably analyze the efficiency of hydrocarbon expulsion, migration and accumulation. Based on analyzing the data of source rock as well as oil and gas in petroliferous basins, in combination with the evolution and development of hydrocarbon generation and expulsion algorithm, this paper discusses how to promote the solution of the above three problems. Firstly, the representation of input parameters in the grid calculation of hydrocarbon generation is solved by the hierarchical evaluation of organic facies of source rock. Secondly, the hydrocarbon generation kinetics model is calibrated from the actual big data of source rock and the simulated experimental data. Thirdly, the efficiency of hydrocarbon expulsion, migration and accumulation is determined from the large data of residual hydrocarbon and migration loss, so as to reduce the uncertainty of hydrocarbon resource evaluation by genetic method.

Key words: whole petroleum system, resource evaluation, hydrocarbon generation, residual hydrocarbon, migration loss

摘要： 全油气系统定量分析技术应用于成因法油气资源评价时主要面临3方面的问题:1生烃量网格计算时如何输入代表性源岩的厚度、总有机碳含量(TOC)和氢指数(HI)以及对应的生烃动力学模型;2如何建立和选择合理的源岩生烃动力学模型参数;3如何合理分析源岩的排烃效率和油气运聚效率。根据含油气盆地源岩和油气数据分析,结合生、排烃算法的演变和发展过程,讨论了如何推动解决以上3个关键问题。一是通过源岩有机相的分级评价来解决在生烃量网格计算中输入参数的代表性问题;二是利用源岩的实测数据和模拟实验数据来联合标定生烃动力学模型;三是利用残留烃数据和运移损失量来确定排烃效率和运聚效率,由此降低成因法油气资源评价的不确定性。
