摘要:
依据成岩序列和成岩阶段划分原理,结合储层岩心观察、铸体薄片、阴极发光,扫描电镜、X射线衍射等资料,对塔里木盆地大北地区巴什基奇克组成岩相定量划分及测井表征进行研究。结果表明:塔里木盆地大北地区巴什基奇克组划分为强压实相、不稳定组分溶蚀相、钙质胶结相、构造裂缝相4种成岩相类型;将综合成岩系数作为成岩相表征的参数,相比前人的研究方法能够很好地解决成岩相定量划分的问题;综合成岩系数的测井资料计算可以实现测井资料模块化处理定量识别成岩相;提出的成岩相识别新方法与岩心分析资料形成良好的印证,方法准确可靠。

Abstract:
Based on the division principle of diagenetic sequence and diagenetic stage, this paper studied the quantitative division and logging identification of diagenetic facies for Bashijiqike Formation in Dabei area of Tarim Basin using reservoir data of core observations, and methods such as cast thin, cathodoluminescence, SEM and X-ray diffraction. The results show that the diagenetic facies can be divided into four types:compaction density facies, corrosion of unstable components facies, calcareous cementation facies, and structural fracture facies. Compared to previous methods, the method used here with comprehensive diagenetic coefficient as characterization parameters can be a good solution to the problem of quantitative division. Comprehensive diagenetic coefficient can be used in logging data processing to identify diagenetic facies. The results obtained from the method agree well with the core analysis data, and the method is accurate and reliable.
