【摘要】 运用原油中的吡咯类含氮化合物,示踪准噶尔盆地彩南油田主区块侏罗系三工河组油藏的原油运移充注过程。原油中吡咯类化合物以烷基咔唑为主,烷基苯并咔唑次之,几乎不含二苯并咔唑。根据1,8—二甲基咔唑/2,4—二甲基咔唑、C3—咔唑/C2—咔唑、G1/G3以及烷基咔唑与烷基苯并咔唑的相对含量等参数的平面分布规律可知,彩南油田东区块彩001—彩007井断层线两侧原油具有不同的充注过程,东侧有北和南两个充注方向,原油进入油藏后向彩1001井、彩006井附近运移。西侧只有来自南方的一个充注方向,原油以断层为通道进入断鼻隆起核部后继续向西充注至构造高点。更多还原

【Abstract】 Pyrrolic nitrogen-bearing compounds ar e used for tracing crude migration and recharging processes of Jurassic Sangonghe reservoir in major blocks of Cainan oilfield,Junggar basin.In the pyrrolic com pounds contain a great amount of alkycarbazoles,a little amount of bensocar-bozoles and little dibenzocarbazoles.Based on the ratio of1,8-dimethylcarba zole/2,4-dimethylcarbazole,C 3-carbazole/C 2-carbazole,G1/G3and the relative amounts of ankycarbazoles and alkybenz ocarbazoles,it is suggested that there exist different recharging regularities in both sides of faulting along Well Cai-001-Well Cai-007in eastern bl ock of Cainan oilfield:in the east side,oils recharged into reservoir from sou th and north directions,and migrated towards Well Cai-1001and Well Cai-0 06;in the west side,oil recharged into reservoir just from south direc-tion ,and entered into center of the fault-nose uplift followed by recharging towar ds west structural highs along passage of the fault.更多还原
