The Impact of Microscopic Pore Network Characteristics on Movable Fluid Properties in Tight Oil Reservoir

Figure 5

Typical pore types in research areas: (a) intergranular pores, feldspar dissolution pores, and kaolinite-related pores with pore-lining chlorite; (b) feldspar and rock matrix dissolution pores; (c) micropores related to calcite and clays; (d) feldspar dissolution pores with illite and I/S mixed layer; (e) microcracks; (f) illite, I/S mixed layer-related micropores. IP: intergranular pore; FDP: feldspar dissolution pore; KRP: kaolinite-related pore; PLC: pore-lining chlorite; RMDP: rock matrix dissolution pore; I/S ML: I/S mixed layer.
