在松辽盆地南部及海拉尔盆地CO_2气藏和片钠铝石研究的基础上,根据中国东北地区CO_2气藏中CO_2的碳同位素、氦同位素,各盆地片钠铝石的碳、氧同位素的数据,以及CO_2气藏(苗)与断裂和火山岩的关系,对中国东北地区CO_2的成因及其与片钠铝石的关系进行了研究.分析认为中国东北地区的CO_2绝大多数为幔源-岩浆成因,且形成片钠铝石的CO_2与幔源-岩浆CO_2同源;片钠铝石是CO_2的"示踪矿物",记录了地质历史时期CO_2的聚集;地层水和原油中溶有大量的无机成因CO_2,经CO_2改造的地层水具有高矿化度及Na~+ 、 K~+、HCO_3~-、CO_3~2-浓度高的特点.依据片钠铝石与CO_2的关系,地层水中离子浓度的变化,以及原油中溶解大量CO_2的事实,总结了中国东北地区幔源-岩浆CO_2赋存的地质记录.
在鬆遼盆地南部及海拉爾盆地CO_2氣藏和片鈉鋁石研究的基礎上,根據中國東北地區CO_2氣藏中CO_2的碳同位素、氦同位素,各盆地片鈉鋁石的碳、氧同位素的數據,以及CO_2氣藏(苗)與斷裂和火山巖的關繫,對中國東北地區CO_2的成因及其與片鈉鋁石的關繫進行瞭研究.分析認為中國東北地區的CO_2絕大多數為幔源-巖漿成因,且形成片鈉鋁石的CO_2與幔源-巖漿CO_2同源;片鈉鋁石是CO_2的"示蹤礦物",記錄瞭地質歷史時期CO_2的聚集;地層水和原油中溶有大量的無機成因CO_2,經CO_2改造的地層水具有高礦化度及Na~+ 、 K~+、HCO_3~-、CO_3~2-濃度高的特點.依據片鈉鋁石與CO_2的關繫,地層水中離子濃度的變化,以及原油中溶解大量CO_2的事實,總結瞭中國東北地區幔源-巖漿CO_2賦存的地質記錄.

The relationship between the genesis of CO_2 and dawsonite in the northeastern China was studied on the base of the research of CO_2 gas reservoirs and dawsonite in the south of Songliao Basin and Hailaer Basin,with the help of the analysis of carbon and helium isotopes of CO_2 gas reservoirs and carbon-oxygen isotopes of dawsonite in each basin respectively,and combining with the relationship between CO_2 gas reservoirs and fault,volcanic rocks.It was found that most of CO_2 in the northeastern China had a mantle-derived magmatic genesis and was homology with the CO_2 forming the dawsonite.As the trace mineral for CO_2,dawsonite can register the accumulation of CO_2 during geological history.High concentration of Na~+,K~+,HCO_3~-and CO_3~2- were displayed owing to the modification of CO_2 in formation water and crude oil.The geology record of mantle-derived magmatogenetic CO_2 was built according to the relationship between dawsonite and CO_2,the changing on the concentration of the ion in formation water and the abundant CO_2 dissolving in crude oil.
