中文摘要：

油气资源潜力评价是评价含油气盆地的关键。目前国内研究对常规与非常规油气资源评价的模式不系统,二者之间没有统一的标准。依据生排烃门限理论,利用生烃潜力法,对四川盆地上三叠系烃源岩的生烃量、排烃量、留烃量3个参数进行计算,建立常规油气、致密油气和页岩油气的模型。研究结果表明：烃源岩生烃总量为4 525.5×10~8t,远景资源量为1 584×10~8t。其中,页岩油气资源约占46.5%,致密油气资源约占44.8%,常规油气资源约占8.7%。该研究系统性地评价出不同地质条件下常规与非常规油气藏的油气资源潜力,为四川盆地油气资源勘探提供重要依据。

英文摘要：

Oil and gas resource evaluation is the key to evaluation of oil and gas bearing basin. The existing evaluation mode for conventional and unconventional oil and gas resource in China is not systematic and there is no standard to define the difference between them. According to hydrocarbon generation and expulsion threshold theory, hydrocarbon generation potential method is used to calculate three parameters for source rock in upper Triassic series in Sichuan Basin including hydrocarbon generation volume, hydrocarbon expulsion volume and hydrocarbon preservation volume and models are built for conventional oil and gas, tight oil and gas and shale oil and gas. The research results show that total hydrocarbon generation volume of source rock is 4 525.5× 10st and prospective resource volume is 1 584×108t, among which shale oil and gas accounts for 46.5%, tight oil and gas accounts for 44. 8% and conventional oil and gas accounts for 8.7%. The research systematically evaluates oil and gas resource potential of conventional and unconventional reservoirs under different geological conditions and provides basis for future oil and gas exploration in Sichuan basin.
