| 摘 要： | 柴达木盆地北缘第三系有丰富的油气储集 ,主要存在于碎屑岩中 ,油气的储集明显与碎屑岩的沉积环境和成岩作用有关。对碎屑岩的储集空间和物性特征起直接的控制作用。通过分析碎屑岩的孔隙类型及在空间的分布特征 ,表明在早、晚成岩作用的转换带有大量的次生溶孔存在 ,是油气的有利富集区。储层物性与方解石成负相关 ,粘土矿物则有不同的变化趋势 ,伊利石的存在使物性变差。

| Abstract: | Plentiful oil and gas reservoir in the Tertiary clastic rocks in north edge of Chaidamu Basin.And the characteristic of reservoir is related with the sedimentary which are controlled directly the reservoir space and porsity and permeability.Pore types and their distribution in the space have been discussed in this paper.It ,s shown that the transform belt of early and late diagenesis has a lot of secondary corrosive pores,and it ,s a potential belt for oil and gas.There is a negative relation between reservoir and calcite.Clay minerals have a complex impacting on the reservoir,and illite makes reservoir worse. |
