摘要：利用微区原位同位素测试、流体包裹体均一化测温、X-射线衍射矿物分析和阴极发光薄片观察与统计等分析手段，系统分析了华庆地区长8段储层岩石学及物性特征，探讨了储层发育的成岩控制因素。结果表明：早期压实作用是长8段低成熟度砂岩原生孔隙降低的重要原因；两期碳酸盐胶结物的广泛发育显著降低了储集孔隙；呈薄膜发育的绿泥石未能有效保护孔隙，自生黏土矿物也是孔隙减少的因素；自生石英填充于溶蚀微孔或附着于颗粒表面，在一定程度上对储层物性产生影响；长8段储层缺乏溶蚀流体的流动空间，碎屑颗粒或前期形成的胶结物未能发生广泛溶蚀，是该区砂岩储集物性较差的另一重要原因。

Abstract: In this study, the authors discuss the diagenetic controlling factors on reservoir development of the Chang-8 section, Huaqing area, on the basis of systematic studies of petrology and reservoir properties, using mi-cro-area, in-situ isotope analysis, homogenization temperature measurement, X-ray diffraction mineral analysis, cathode luminescence observation and coupled with regular thin-section analysis. The results indicate that the early compaction exerting on the low-maturity sandstone of the study area results in dramatic primary porosity decrease. Wide occurrence of two-stage carbonate cementation largely decreases reservoir property, and thin-film chlorite does not protect primary porosity effectively, authigenic clay mineral cementation also contributes to porosity loss. The authigenic quartz filling in dissolution micropores or coating to particle surface causes porosity decrease at certain extent. Moreover, the dissolution of grains or cement does not occur widely due to lack of flowing pathways for dis-solving fluids, which is another major cause for low reservoir quality in the study area.

Keywords: Ordos Basin Huaqing area Chang-8 section reservoir carbonate cementation clay mineral ce-mentation diagenetic controlling factors
