摘要:

四川盆地川中地区大安寨段致密灰岩属于典型的“致密油”储层,在研究其储层特征的同时,重新划分了亮晶介壳灰岩、泥质介壳灰岩、泥晶介壳灰岩及结晶灰岩等 4 类主要的储集岩性,详细研究了溶蚀孔洞、次生微孔、裂缝及纳米级孔这 4 类储集空间的特征,建立了致密灰岩储层连续型似“网状”储集空间组合模型。 通过分析沉积微相、溶蚀作用和构造作用对储层的控制和影响,指出在低能介壳滩主要发育基质微孔储集层,在高能介壳滩主要发育溶蚀孔洞储集层,由此确定了多种储集空间类型组合叠置、大面积连续分布的储层发育模式。 基质微孔与溶蚀孔洞型储集层连续分布区是致密灰岩储层的“甜点”区。

Abstract:

The tight limestone of Da’anzhai member in the central Sichuan Basin belongs to typical “tight oil” reservoir. The reservoir lithology was reclassified to crystallized shelly limestone, argillaceous shelly limestone, micrite shelly limestone and crystalline limestone. The characteristics of four types of reservoir space were studied, including dissolved pores-vugs, secondary micropores, fractures and nanopores, and a reservoir space model for tight limestone was established, which seems like a“nets-system”. Through the analysis of the effects of sedimentary microfacies, dissolution and tectonism on the reservoir, it was pointed out that the matrix pores mainly developed in low energy shell beach, and dissolved pores-vugs mainly developed in high energy shell beach. The reservoir development model is a kind of combination by multiple reservoir space types, which distributed largely and continuously. The “sweet spot” of tight limestone is the pores-vugs-fractures reservoir developed on the area where are full of matrix pores and dissolved pores-vugs.
