Abstract: At present, resource assessment technology can not meet the needs of integrated evaluation and stereoscopic exploration of conventional and unconventional oil-gas resources. The whole pertoleum system theory provides theoretical guidance for the evaluation of distribution and potential of conventional and unconventional oil-gas resources. Based on the investigation of conventional and unconventional oil-gas resource assessment methods, combined with the progress of geological theory and basin modeling techniques, this paper puts forward a conventional and unconventional integrated resource assessment method based on whole petroleum system theory and TSM basin simulation technology. The applicability and advantages of the new method are analyzed through the application in typical areas. The future development prospects are also put forward. From the perspective of source analysis, conventional and unconventional oil-gas resources are derived from the thermal degradation of organic matter, which is the result of "co-evolution of source and reservoir and differential evolution of source and reservoir" and has the basis for integrated evaluation. Based on the analysis of the complete evolution model of hydrocarbon generation-expulsion-retention, the evolution model of oil discharge and cracking and the evolution process of gas in the source rock, an integrated resource assessment method and process of conventional and unconventional oil-gas resources are established. The new method can be used to simulate the whole process of oil-gas formation and evolution and calculate the resource amount of the in-source system and the external-source system. The new method reflects the integrity of orderly symbiosis of multiple types of oil-gas resources and the dynamic evolution process of oil-gas. The evaluation process is more scientific, and it has unique advantages in the macro control of the overall resource potential of the basin. However, in the next step, it is still necessary to strengthen the research on the fine evaluation of source rock and the simulation technology of oil-gas migration and accumulation, so that the resource assessment results can better serve the exploration deployment.

摘要: 目前,资源评价技术已不能满足常规-非常规油气资源一体化评价和立体勘探的需求,而"全油气系统"理论为评价常规、非常规油气及潜力分布提供了理论指导。在常规、非常规油气资源评价方法调研的基础上,结合地质理论研究进展、模拟实验以及盆地模拟技术的进步,提出了基于全油气系统理论和TSM盆地模拟技术的常规-非常规油气资源一体化评价新方法,通过在典型地区的应用实例,分析了新方法的适用性、优势及发展前景。从根源上来说,常规与非常规油气均来自有机质的生烃热降解,是"源-储协同演化、源-藏差异演化"的结果,具备开展一体化评价的基础;在分析烃源岩完整的生烃—排烃—滞留油气演化模式、排出油裂解演化模式和源内气演化过程的基础上,建立了常规-非常规油气资源一体化评价方法和流程,可统一开展源内体系和源外体系油气形成演化全过程的模拟和资源量计算。新方法体现了多类型油气资源有序共生的完整性和油气动态演化过程,其评价过程更科学且在盆地整体资源潜力的宏观把控方面具有独到优势。下一步仍需在烃源岩精细评价和油气运聚模拟技术方面加强研究,使资源评价结果更好地服务于勘探部署。
