| 摘 要： | 以岩心和测井分析为基础，通过对沈８４块沙三四段的岩石类型及其组合、沉积韵律、原生沉积构造、砂岩的粒度分布特征、古生物化石及砂体形态等沉积相标志的研究，确定其为一套扇三角洲相沉积，可进一步分为扇三角洲平原、扇三角洲前缘及前扇三角洲三个亚相．区内以扇三角洲前缘亚相沉积为主体，主要包括水下分流河道、分流河道边部、河间薄层砂、前缘席状砂、水下分流河道间等微相类型．此外，以单井微相分析为基础，结合大量的地球物理测井及录井资料，研究了区块内沙三四段四个油层组、３０个小层、６３个单层的沉积微相平面分布规律．

| Abstract: | It is held that E 4 S 3 submember in Block Shen 84 is a set of fan delta
deposition according to the analysis of various facies marks, including rock types and their
combination, sedimentary rhythm, primary sedimentary structure, grainsize distribution feature
of sandstone, fossils, sandbody morphology, and so on. It can be divided into three subfacies,
i.e. fan delta plain, fan delta front and fore fan delta. And fan delta front subfacies is main
sedimentary microfacies, which includes subageous distributary channel, distributary channel
edge, interchannel thin layer sand, front sheet sand, interchannel etc. In addition, the
microfacies plane distribution patterns of 63 single layers, 30 substrata and 4 oil reservoir sets
in this block are studied according to the microfacies analysis of single well and a vast amount
of logging data. |
