微观作用是引起封闭式孔隙、细网通道与粗网通道之间的流体交换。
The microscopic effect of capillary causes fluid exchange between closed pores and fluid exchange between fine network channels and thick network channels.
粗化时间延长，孔隙形状更接近球形。
The shape of pores was close to globularity when the coarsening time was prolonged.
该区储层具有较低的排驱压力和毛细管压力中值，微观孔隙结构发育良好，属于中-粗孔喉。
The reservoir also features in low displacement pressure, low median capillary pressure, well-developed microscopic pore structure, and medium-to-large pore throat.
低排驱压力-粗孔喉为最好的孔隙结构类型。
The best pore structure is of the low displacement pressure-coarse pore throat.
晶间孔隙主要发育在陡一段下部的粗粉晶含灰云岩中，白云石晶体为自形晶和半自形晶。
The former are mainly developed in the coarsesilt grained, euhedral and semi-euhedral crystalline calcitic dolomites occurring in the lower part of the first member of the Doushantuo Formation.
