The research shows that in the Yinggehai basin, the formation of CO_(2) reservoir which is crust-sourced and crust-mental-mixed-sourced, mainly controlled by local action of hot fluid in the mud diapir area which is multi terms and multi zones and by physical-chemical mechanism of very thick marine calcareous sandstone and mudstone of Pliocene-Miocene. The volcano- and mantle-sourced CO_(2) in the Qiongdongnan basin and Pearl River Mouth basin is mainly controlled by volcanos activities and by the exist of large faults which reached to base to connect the gas from the mantle. According to different mechanism ang formation of reservoir os the the crustal rock-chemical genesis and volcano-and mantle-sourced CO_(2), we can follow the source of it, analysis and predict the migration and accumulation and distribution model of gas and espacially CO_(2), so as to help to make the plan of petroleum exploration and reduce the risk of exploration.

认为：莺歌海盆地壳源型及壳幔混合型CO2的形成及富集成藏，主要受控于泥底辟热流体晚期分层、分块和多期的局部上侵活动，和巨厚的上新统—中新统海相含钙砂泥岩的物理化学综合作用，且CO2运聚分布规律亦具多期和分层、分区的特点；琼东南盆地东部及珠江口盆地火山幔源成因型CO2则主要受控于幔源型火山活动和沟通深部气源的基底深大断裂的导气配置作用，CO2运聚富集规律与幔源型火山活动及深大断裂的发育展布密切相关，CO2主要来自地壳深部幔源火山活动所伴生的大量CO2；因此，根据壳源岩石化学成因型CO2与火山幔源成因型CO2不同成因机理及成藏条件，可以追踪CO2气源，可分析和预测天然气尤其是CO2的运聚分布规律，可为天然气勘探部署及决策提供依据，可减少和降低勘探风险。

The evolutionary model organic beach or reef reservoir, controlling factors of which are sedimentation, digenesis and tectonics ,are established according to the result of sedimentary facies and digenesis. At last regional distribution of reservoir has been predicted. Comprehensive study indicates the dark, 50-300 m thick upper Permian series, which is rich in the organic material and biota , is beneficial to formation and protection of petroleum and natural gas. Moreover the stratigraphy possess with better reservoir ability. The reservoir distributed in shallow glacis along Beichuan Tongkou - Guangyuan Changjianggou ,He 12 well - She 1 well - Jiange - Cangxi Yongningpu -Long 4 well - Bian 1 well in Wujiaping stage and in platform edge beach along Beichuan Tongkou - Jiangyou Shuigentou - Jiange -Cangxi Yongningpu - Nanjiang .

综合以上，本文认为研究区上二叠统地层厚50—300m，颜色较深、生物含量多、富含有机质，并且该套地层自形成后，大多直接进入埋藏成岩环境，是一套十分有利于油气的形成与保存的地层；同时该套地层的局部层段具有一定的储集性能，在吴家坪期储层主要分布在北川通口—广元长江沟、河12井—射1井—剑阁—苍溪永宁铺—龙4井—扁1井一带，在长兴期储层主要分布在北川通口—江油水根头—剑阁—苍溪永宁铺—南江一线。
