万金塔CO_2气田位于吉林省农安县境内。地质构造上位于松辽盆地东南隆起区德惠凹陷西缘,农安——万金塔背斜北端(图1)。自1964年在构造东翼万井塔首次CO_2气喷以来,相继钻了4口探井,井井见CO_2气。其中,万_2、万_4、万_6井经测试均获工业CO_2气流。主产气层气流的CO_2含量高达97％以上,单井日产量瞬时测算为20000-131257m~2,地质储量估算为××10~6m~3,具开发价值。
The Wanjitata CO_2 gas field is located in Nong’an County, Jilin Province. Geological structure is located in the southeast margin of the Dehui depression in the southeast uplift of the Songliao Basin, Nong’an - the northern end of the Wanjunta anticline (Figure 1). Since 1964, in the construction of East Wing wells first CO_2 gas jet, have been drilled four exploration wells, wells see CO_2 gas. Among them, Wan _2, Wan _4, Wan _6 wells were tested by industrial CO_2 airflow. The CO 2 content in the main producing gas flow reaches as high as 97%. The daily output of single well is estimated instantaneously to 20000-131257m ~ 2, and the geological reserve is estimated to be ××10 ~ 6m ~ 3 with development value.
