本文以鄂尔多斯盆地环县-西峰地区延长组长9油层组为研究对象，利用钻孔岩心、薄片鉴定、扫描电镜等资料，对长9油层组砂岩储层中自生绿泥石的产状、成因及其与形成环境的关系进行研究。结果表明，自生绿泥石主要以孔隙的环边衬里形式出现，其沉淀作用发生在沉积期后而不是沉积阶段或沉积作用以前，其分布对应于辫状河三角洲前缘水下沉积环境。

In the light of cores, thin sections and scanning electron micrographs, the present paper focuses on the occurrence, genesis and bearings on the genetic conditions of the authigenic chlorite from the sandstone reservoirs in the Chang-9 oil measures of the Yanchang Formation in the Huanxian-Xifeng region, Ordos Basin. The authigenic chlorite occurs as the rims of the pores, and generated after the deposition, i. e. , the early stages of early diagenesis rather than during and/or before the deposition. The distribution of the authigenic chlorite in the Huanxian-Maling-Ningxian zone suggests the braided delta front subaqueous sedimentary environments in the study area.
