摘　　要：在油气资源评价方法研究与优选的基础上,建立了针对中国石化探区“常规—非常规”以及“地质—经济—生态”2个一体化的“十三五”油气资源评价方法流程和技术体系。研究了油气资源评价关键参数,包括基于TSM盆地模拟技术构建了适用于我国不同类型盆地/地区烃源岩完整的生—排—滞留烃演化模式、产率模型;建立了基于典型刻度区解剖的资源评价关键参数获取方法和评价指标。通过对近50个盆地/地区全部含油气层系(震旦系—第四系)的系统评价,落实了中国石化矿权区常规油气、致密油气、页岩油气以及煤层气等7种不同类型油气的地质资源,明确了其油气资源的经济可采性和生态环境影响程度。通过资源分布特征研究,进一步明确了下一步勘探领域和方向,指出深层—超深层是常规油气的主攻方向,非常规尤其是页岩油气是未来我国油气增储上产的重要领域,海域探区也具备广阔的勘探前景。同时,资源评价结果为油公司“十四五”规划和勘探部署提供了重要依据。Based on the research and optimization of oil and gas resource assessment methods,a comprehensive oil and gas resource assessment method process and technical system,which integrated assessment of conventional and unconventional resources as well as assessment of geological,economic and ecological aspects,were established for SINOPEC-controlled exploration areas during the 13th Five-Year Plan period.The study focused on the key parameters for resource assessment,including a complete hydrocarbon generation-expulsion-retention evolution model and productivity model applicable to different types of source rocks in different basins/regions in China based on TSM basin simulation technology,and a key parameter acquisition method and assessment indicators for resource assess-ment based on typical calibrated unit dissection.Through systematic assessment of all oil and gas bearing layers(from Sinian system to Quaternary system)of nearly 50 basins/regions in SINOPEC-controlled exploration areas,the geological resources of seven different types of oil and gas,including conventional oil and gas,tight oil and gas,shale oil and gas,and coalbed methane were assessed,which clarified the economical recoverability and environmental impact of oil and gas resources.By studying the resource distribution characteristics,the future exploration areas and directions were further clarified.It is indicated that the deep-ultra deep layers are the main focus for conventional oil and gas exploration,while unconventional resources,especially shale oil and gas,are important areas for increasing oil and gas reserves and production in the future.The sea exploration area also has broad exploration prospects.At the same time,the results of resource assessment provide important basis for the planning and exploration deployment of oil companies during the 14th Five-Year Plan period.
