长石溶蚀作用对储层物性的影响——以渤海湾盆地东营凹陷为例

doi:10.11743/ogg20130608

Abstract

Abstract: Sandstone reservoirs in Dongying Sag,the Bohai Bay Basin are rich in feldspar,dissolution of which is very common and has an important influence on reservoir physical properties.Polarizing microscope,SEM and X-ray powder diffraction technologies were used to study the distribution characteristics of feldspar and its dissolution products in the sandstone reservoirs in Dongying sag.The content of feldspar varies in different areas.The highest content of feldspar occurs in the north,followed by the south,and the lowest is in the central area.Vertically,Es¹ is the richest in content of feldspar,followed by Es² and Es⁴ f,and Es³ is lowest.The main dissolution products of feldspar in the sandstone reservoirs in Dongying sag include kaolinite,illite and chlorite.The transformation kaolinite to illite and chlorite causes the decrease of content of kaolinite.The illite and chlorite in the shallow layer are mainly transformed from I/S,while they come from kaolinitic alteration in the deep layer.The content of I/S is high in shallow layer,and reduces with the increasing depth.

Key words: feldspar, dissolution, clay mineral, Dongying sag, Bohai bay basin
