| 摘 要： | 通过岩心、薄片等方法对新场气田中侏罗统沙溪组一段的储集特征进行了详细研究,对其储集物性的主控因素展开探讨,认为成岩作用是影响物性的重要因素.得出方解石胶结是导致孔隙度减少的主要原因,衬垫(或环边)绿泥石则导致渗透率变差,溶蚀作用形成的次生孔隙对孔隙度增加作出了贡献,但对渗透率无明显的建设性.

| Abstract: | Characters of Shaximiao formation are detailly researched by means of core?thin section in this paper, and the main controlling factors are deeply discussed and diagenesis is known the important factor to influences the reservoir characters. A conclusion that calcite cementation causes porosity reducing, grasket (or margin) chlorite leads to permeability worsening is drawn, the soluted secondary pore have a contribution to porosity, but not be obviously constructive to permeability. |
