摘要: 川中八角场大安寨组介壳灰岩储集空间由成岩微缝、晶间缝、溶孔和构造微缝组成,以成岩微缝为主,其次为晶间缝和微溶孔、缝,构造缝主要起渗滤通道作用。低孔低渗、微孔喉为主、大孔隙表面积和亲油性决定其主要成为储气层,并控制着凝析气藏的聚集、油气分布、开采中产能及油气性质的变化。气藏外圈东南部向斜溶孔发育,成为储油层。

Abstract: The reservoir space of the shell carbonate is made up of structure crack, tiny diagenesis crack, crystal crack and corrosion pores. The bigger structure cracks which may reservoir a little oil mainly play a part of permeable passage. The tiny diagenesis cracks are mainly the reservoir space of condensate gas. The reservoir rock is characterized by low permeability and porosity, tiny throat, larger surface and affinity for oil. These characteristics have controlled the accumulation and the distribution of oil and condensate gas,and the behaviour of condensate gas reservoir.
