摘要
本文是在研究了大量海拉尔盆地钻井岩心铸体薄片的基础上运用阴极发光、电子探针、扫描电镜、能谱及稳定同位素等多种分析成果,讨论了盆地内主要储集层的侏罗-白垩系砂岩中与孔隙发育关系密切的各种成岩变化;论述了该区与大气水、淡水有关的成岩作用的识别标志,并结合各种成岩变化之间的相互关系,建立了砂岩的成岩作用共生序列。对认识盆地的埋藏史、孔隙演化史和储层发育都有着重要的理论和现实意义。
This article deals with various diagenesis which are closely related to the development of pores in the Jurassic -Cretaceous sandstone reservoirs. Through the analysis on a large number of cast thin-sections of cores in the Hailaer Basin and many measurements of cath-doluminence, electronic micro - probe, SEM & EDX, isotope etc. , the criteria for the recognition of diagenesis caused by meteoric water apd freshwater have been discussed in this paper. Furthermore, the diagenetic sequences are reconstructed in the terms of differentiated diagenesis patterns. Therefore, it is the both theoretic and practical significance to study the burial history of basins, the evolution of pores and reservoir development.
