Figure 3

Thin section images, binary images, and pore size distribution of dolostone samples. (a) Intercrystalline pores and intercrystal dissolved pores in sample S2, well BT5, 5782.08 m, ∈1x, medium crystalline dolomite. (b) Intercrystal dissolved pores in sample S32, well MB1, 6002.98 m, ∈2s, silty crystalline dolomite. (c) Fracture and intercrystal dissolved pores in sample S22, well YQ6, 7061.07 m, ∈3ql, coarse crystalline dolomite. (d–f) The binary image of samples S2, S32, and S22, where the white and black pixel represents pore and solid matrix, respectively. (g–l) The pore size distribution and porosity of samples S2, S32, S22, S5, S4, and S19 corresponding to images in Figure 2 and this figure.
