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。
Pyrrole nitrogen compounds in crude oil are used to trace the migration and filling of crude oil in the reservoir of the Sangonghe Formation, Jurassic in the main block of the Cainan oilfield in the Junggar Basin. Pyrrole compounds in crude oil mainly alkyl carbazole, alkyl benzocarbazole followed, almost no dibenzocarbazole. According to the relative content of 1,8-dimethylcarbazole / 2,4-dimethylcarbazole, C3-carbazole / C2-carbazole, G1 / G3 and alkylcarbazole with alkylbenzocarbazole The law of plane distribution of the parameters shows that the crude oil on both sides of the fault line in Block No. 001- Cai 007 in the eastern block of the Cainan oilfield has different filling processes, with the north and south filling directions on the east side. After the crude oil enters the reservoir, Well, color 006 well near the migration. The west side is only a filling direction from the south. Crude oil enters the core of the off-nose bulge as a channel and continues to be injected westward to the structural high point.
