摘要：

海拉尔盆地碳钠铝石的形成与CO2的分压有关,含有碳钢铝石的井都分布于CO2分压的高值区;但却并非凡是CO2气藏都含有碳钠铝石,因为CO2只是形成碳钢铝石的条件之一.CO2为无机成因,受控于燕山期的岩浆活动;而岩浆活动又促进有机质的成熟向烃类转化.三者分布的依存关系表明,根据碳钠铝石的分布,可以预测油气和CO2的有利勘探区.

Abstract:

The formation of NaAlCO3 (OH)2 in the. Hailar Basin was related to CO2 Pressure, and all NaAlCO3(OH)2-bearing wells are distributed in high value areas of CO2 pr essu re. Bu t it is a fact that not all CO2 reservoirs contain NaAlCO3(OH)2 since CO2 is just one of the factors to form this minerals.The CO2 in the basin is of inorganic genesis and was dominated by Yenshan magmatic activity while magmatic activity impelled organic matter to matuate and evolute. Accoriding to the coexisting relationship between CO2, NaAlCO3 (OH )2 and hydrocarbon, and the distribution of NaAlCO3(OH)2, target areas of oil and gas as well as CO2 exploration could be predicted.
