摘要(Abstract)：

从CO2 分布特征入手 ,利用其天然气碳同位素图版分析了松辽盆地南部CO2 成因类型 ;利用CO2 百分含量及地层水HCO-3 含量在平面上的变化 ,指明了孤店地区气源方向及CO2 成因类型为无机成因碳酸盐矿物分解或与粘土反应而成 ;建立了孤店油气田侧向运移上生、下储的成藏模式及万金塔气藏垂向运移下生、上储的成藏模式。通过评价工作 ,找出了松辽盆地南部CO2 平面分布规律及富集条件。
This paper analyzes the genesis of the CO 2 of the southern part of Songliao Basin using carbon isotope chart of natural gas starting with the distribution characteristic of CO 2. Then it indicates the gas source direction of Gudian area and that the genesis type of CO 2 is inorganic carbonate mineral decomposition or clay reaction using the areal change of the percentage content of CO 2and the HCO 3 - content in formation water. It constructs the reservoir formation pattern of the lateral migration with upper source rock and lower reservoir of Gudian oil and gas and the reservoir pattern of vertical migration with lower source rock and upper reservoir of Wanjinta gas reservoir. Through the evaluation, it identifies the areal distribution rule and enrichment condition of the CO 2 in the southern part of Songliao Basin.
