中文摘要:    四川盆地油气勘探开发历史悠久,目前已经成为中国重要的油气能源基地。为何四川盆地油气勘探开发长久不衰,未来四川盆地油气勘探开发的方向在哪里。为此,在对国内外超级油气盆地调研的基础上,从盆地地质结构、油气资源规模、类型、储量产量、和空间分布等方面进行了对标分析,并指出了油气勘探潜力和方向。研究结果表明:①四川盆地完全符合超级油气盆地的各项条件,是一个名副其实的超级富气盆地,勘探开发潜力巨大;②四川超级富气盆地其常规与非常规油气领域都是重要的勘探开发对象,油气勘探开发过程中应“常非并举”,油气储量、产量将不断攀升;③常规天然气领域仍然是围绕德阳—安岳裂陷向北进行风险勘探和评价勘探,层位上重点是震旦系和寒武系;页岩气应重点围绕下志留统龙马溪组深水相和深层叠合区域开展勘探开发;致密气则围绕川中—川西过渡带开展评价和建产;致密油(页岩油)应重点在川中北部的中侏罗统沙溪庙组一段、下侏罗统大安寨段开展目标优选和先导实验。
英文摘要:    The Sichuan Basin has a long history of oil and gas exploration and development, and has become an important oil and gas base in China. Why has the oil and gas exploration and development in the Sichuan Basin lasted for such a long time? Where is the future directions of oil and gas exploration and development in the Sichuan Basin? In order to analyze the reasons for the long-term development of oil and gas exploration in the Sichuan Basin, based on the investigation of super oil and gas basins at home and abroad,
benchmarking analysis was carried out from the aspects of basin geological structure, scale and type of oil and gas resources, oil and gas reserves and production, and spatial distribution of oil and gas, and the potential and directions of oil and gas exploration of this basin are pointed out. The study results show that: (1) The Sichuan Basin fully meets all the conditions of a super oil and gas basin and is a veritable super gas-rich basin with great exploration and development potential. (2) Both its conventional and unconventional oil and gas domains are important exploration and development objects, and should be paid equal attention in the process of oil and gas exploration and development, then its oil and gas reserves and production will continue to rise. (3) For the conventional natural gas domain, risk exploration and evaluation exploration should still be carried out northward around the Deyang-Anyue rift, with the emphasis on the Sinian and Cambrian in horizon. For shale gas, emphasis should be placed on exploration and development around the superimposed areas of deep water and deep layers of the Longmaxi Formation. For tight gas, evaluation and productivity construction should be around the transition zone between central Sichuan Basin and western Sichuan Basin. For tight oil (shale oil), target optimization and pilot experiment should be carried out in the first member of the Shaximiao Formation and the Daanzhai Member of the Ziliujing Formation in the north of the central Sichuan Basin.
