| 摘要: |
| 本文依据铸体薄片、电镜扫描、镜质体反射率、有机质成熟度等分析化验资料并结合岩石学特征,研究了长庆白豹油田长3、长4+5油层组的主要成岩作用,认为主要有压实作用、胶结作用、溶蚀作用和烃类侵位作用,而压溶作用不显著,总体上以破坏性成岩作用为主。总结了各成岩阶段的特征,建立了成岩演化序列。采用遗传神经网络算法求取成岩储集相参数,确定了A、B、C、D四种成岩储集相类型及其平面展布。 |

| Abstract: |
| The diagenesis of the Chang-3 and Chang 4+5 oil measures in the Baibao Oil Field,Changqing is treated on the basis of the integration of thin section analysis,electron microprobe scanning,vitrinite reflectance and organic matter maturity.The diagenetic stages comprise compaction,cementation,dissolution and hydrocarbon emplacement.Four diagenetic reservoir facies types and their planar distribution have been ascertained with the aid of the genetic artificial neural network. |
| Key words: Baibao Oil Field diagenesis diagenetic sequence diagenetic reservoir facies |
