摘要：

蒙古林油田阿尔善组砾岩储层,为富含火山岩屑的特殊类型储层,可分为复成分砾岩、凝灰质砾岩及火山角砾岩三大类。具低成分成熟度和低结构成熟度特点,以粗杂基支撑的砾岩含油物性最好,主要储集空间为粒间基质溶蚀孔隙,为中孔细喉低渗型储层。复成分砾岩以粒间溶蚀孔隙为主,渗透性较好;凝灰质砾岩和火山角砾岩分别以组分内孔隙和残余粒间孔隙为主,渗透性均较差。

Abstract:

The conglomerate reservoir of the Alshan Formation in Mongolin Oilfield is special in containing abundant volcanic debris. The reservoir could be divided into polygenic conglomerate, tuff conglomerate and volcanic breccia.The reservoir is characterized by low compositional maturity and low textural maturity.The conglomerate with coarse complex matrix is more favourable for oil reservation, and its main reservoiring spaces are intergranular matrix soluted pores. The polygenic conglomerate contains primarily intergranular soluted pores and has better permeability; the tuff conglomerate and volcanic briccia contain respectively intragranular pores and residual intergranular pores, and their permeability are poor.
