摘要
从油藏地球化学角度出发 ,根据原油中C9～C17支链烷烃和环烷烃的色谱指纹特征、轻烃指纹对比、轻烃成熟度指标 ,对埕北 30潜山油藏的连通性进行了研究。研究结果表明 ,埕北 30潜山油藏各井原油的油源相同 ,但原油中C9～C17环烷烃和支链烷烃指纹、轻烃指纹、轻烃成熟度均存在一定的差异 ,油藏在横向上是不连通的 ;各油藏单元的古生界和太古界原油色谱指纹一致 ,其储层在纵向上是连通的。
The geochemistry analysis on the crude samples obtained from the wells in the Chengbei 30 buried hill reservoir was made. The reservoir continuity of this area was discussed. The gas chromatogram fingerprint characteristics of C 9-C 17 branched and cyclic alkane, the light hydrocarbon fingerprint correlation and the light hydrocarbon maturity in the crude show that the hydrocarbon sources of all wells in the Chengbei 30 buried hill reservoir are same. The layers are vertically continued in the same well, but not continued in the horizontal direction.
