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。

2Nd, thorough analysis: The Earth may say is an extremely marvelous thermonuclear reactor, when the earth interior pressure achieved certain critical, in the Earth material may decay the nuclear matter is called as the thermonuclear material, can have the thermonuclear reaction, thus has the huge energy, then the melted partial materials, form the rock magma are the liquid state materials, this response stratification plane is possibly many stratification planes, first possibly is located between the earth's crust and the mantle, upward next two transfers, displays for the light density material diastrophism as well as density upper mantle material phenomena and so on solidification; Under second possibly is located between the mantle and the core, the pressure is more formidable, causes not not easily to have the thermonuclear reaction thermonuclear material to have the response, forms the relative quite stable liquefied material level, simultaneously is upward next two transfers, forms the counter-flow phenomenon which the high density under mantle as well as the high density core material contact liquefies and is far away cools; These material periodicity regular movements and so on convection as well as Earth polar axis rotation are possibly the basic source powers which the terrestrial magnetic field produces.
深入剖析:地球可以说是一个非常奇妙的热核反应堆,当地球内部的压力达到一定的临界,地球物质中可衰变的核物质统称为热核物质,就会发生热核反应,从而产生巨大的能量,进而融化部分物质,形成岩浆即液态物质,这个反应层面可能是多个层面,第一层可能位于地壳与地幔之间,向上下两边对流,表现为轻密度物质的地壳运动以及中密度上地幔物质的固化等现象;第二层可能位于下地幔与地核之间,压力更为强大,引起不易发生热核反应的热核物质发生反应,形成相对比较稳定的液化物质层,同时向上下两边对流,形成中高密度的下地幔以及高密度地核物质的接触液化和远离冷却的对流现象;这些对流以及地球极轴自转等物质周期性规律性运动可能是地球磁场产生的根本源动力。
