摘要：

大庆头台油田茂62-92 注水井不断流出的大量原油与生产井开采层位(扶余-杨大城子) 的原油在地球化学特征方面存在显着差异:(1) 原油密度及残碳量低;(2)含蜡量、饱和烃含量及芳烃含量高;(3) 全烃指标差异明显。但与邻区油田的葡萄花油层地球化学性质相近,由此说明茂62-92 注水井的原油比生产井油层层位浅,即此原油并非扶余-杨大城子油层,而是葡萄花油层。

Abstract:

Crude oil produced in Mao 62-92 injection well in Tuotai Oilfield,Daqing Oilfields differs differently from the crude oil of recovery bed from production well(Fuyu Yangdachengzi oil reservoir)in geochemical properties:1.the density and residual carbon of the crude oil are low;2.the contents of paraffin,saturated hydrocarbon and aromatic hydrocarbon are high;3.whole hydrocarbon index differs clearly from that of recovery bed crude oil.But that the geochemical properties of injection well crude oil are similar to that of Putaohua oil reservoir in neighbouring oilfield,this indicates that the crude oil of the injection well is buried shallower than that of producton well,that is to say,the first one belongs to Putaohua oil reservoir.

Key words: injection well, suspicious oil reservoir, recognition, geochemistry, Tuotai Oilfield
