| 摘 要： | CO2的成因问题是当今地球科学的前沿和热点问题.中国含油气盆地CO2的成因类型分为有机成因和无机成因两大类,以无机成因为主.CO2无机成因包括:未脱气地幔岩浆脱气作用;地壳岩石熔融脱气作用;海相碳酸盐岩热分解作用;碳酸盐胶结物热分解作用.地化研究表明,全球含油气盆地已发现的CO2气田(藏)中,CO2主要是由未脱气地幔的脱气作用贡献的.

| Abstract: | CO 2 's cause of formation is the front position and hotspot of geoscience at present. The formation in China's oil-gas containing basin can be divided into two types: organic and non-organic, with the latter being the chief cause of formation. CO 2 's non-organic cause of formation includes the following: the gas-separation function of the earth's non-gas-separation from mantle magma, the gas-separation function of the earth's crust and rock, the function of hot decomposition from sea facies and carbonate as well as the function of hot decomposition from carbonate rock and cementation substance. According to the study of geological chemistry , in all the CO 2 gas reservoirs of those discovered oil-gas containing basins, CO 2 is chiefly the result of the gas-separation function of the earth's gas-separation mantle. |
