Fig. 2. Photos showing the development characteristics of pores in hydrogen-rich organic matter. (a) & (b): Well YZ1, kerogen, telalginite, with pores that are angular, different in size, but uneven in distribution due to the original structure. (c) & (d): Well JY1, solid bitumen, with pores that are round or elliptical, and uniform in distribution, but different sizes ranging 2-1000 nm, and original outlines of small pores observed in large pores.
