| 摘 要： | 绿泥石膜是鄂尔多斯盆地胡尖山地区延长组长6油层组储集岩中最常见的粘土矿物之一。根据铸体薄片和X衍射分析得出：绿泥石膜形成于早成岩时期,该层段孔隙度随着绿泥石膜含量的增加而增大,对该地区储层孔隙度具有建设性作用。这种作用主要体现在抑制石英次生加大、增加颗粒间抗压实强度、抑制压溶以及挤占碳酸盐岩胶结物生长空间三个方面。

| Abstract: | Chlorite thin film is one of the major clay mineral which developed very common in the Chang6 oil group reservoir rock of Yanchang formation in Hujianshan area.From the casting thin section and X-ray analysis,we know that： chlorite thin film formed at the early diagenesis stage,for this stage the porosity increased with the chlorite increased,it means chlorite played as a constructive role for the reservoir porosity in this area.This effect mainly showed from the following 3 aspects： restrained quartz secondary developed,enhanced inter grain anti-compaction strength,restrained pressolution and occupied carbonate cement development space. |
