摘　　要：油气资源评价的盆地模拟方法因其能够定量表达评价结果且工作效率高受到广泛重视并在油气资源的勘探开发中发挥着重要作用。当前,油气资源评价的盆地模拟方法面临着3方面的挑战:从“源岩到圈闭”的经典油气系统理论不能有效地指导非常规油气的资源评价;盆地数值模拟技术不能有效地拓展到复杂构造演化区;油气资源的预测评价结果和综合开发风险表征困难。全油气系统理论的创立和定量评价方法的提出为应对当前挑战开拓了新思路、新途径。应用全油气系统理论来阐述常规和非常规油气资源的联合成因模式与相互制约机制,结合盆地数值模拟和钻探结果的统计模拟开展研究,提出了全油气系统的常规油气、致密油气、页岩油气、富油气“甜点”、构造破坏烃量、油气资源综合风险的预测评价6大关键技术,并列举了应用实例。研究结果表明,全油气系统的新理论、新技术不仅能够预测油气资源的形成分布,还能够评价油气资源量及其钻探开采风险,为创建具有独立知识产权的新一代盆地模拟系统创造了条件。The basin modeling method for evaluation of oil-gas resources has been widely paid attention and plays an important role in the exploration and development of hydrocarbon resources because of its ability to quantitatively express evaluation results and high work efficiency.At present,basin modeling method faces with three challenges,including that the classical petroleum system theory from source to trap cannot effectively guide the evaluation of unconventional oil-gas resources,that the application of basin numerical simulation technology cannot be effectively expanded to complex tectonic evolution areas,and that it is difficult to predict the evaluation results of oil-gas resources and characterize the comprehensive risk of reservoir development.The establishment of whole petroleum system theory and the proposal of quantitative evaluation methods have opened up new ideas and approaches to address current challenges.The combined genetic model and mutual constraint mechanism of conventional and unconventional oil-gas resources were elaborated using the whole petroleum system theory,and further a study was carried out based on basin numerical simulation and the statistical simulation of drilling results.On this basis,six key technologies were proposed for predicting and evaluating the comprehensive risks of conventional oil and gas,tight oil and gas,shale oil and gas,oil-gas sweet spots,hydrocarbon amount destroyed by tectonic events,and oil-gas resources in whole petroleum system,and application examples were also listed.The results show that the new theories and technologies of whole petroleum system can not only predict the formation and distribution of oil-gas resources,but also evaluate the amount of oil-gas resources and their drilling and exploitation risks,creating conditions for establishing a new generation of basin modeling system with independent intellectual property rights.
