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

Table 2

Statistics of reservoir characteristic parameters from different spectrums of samples.

Well	Radius max of throat (μm)	Mainstream throat radius (μm)	Microcrack distribution	Clay content (%)	Movable fluid percentage (%)	Patterns of distribution
C7-1	1.168	0.464	Microcrack	13.6	57.8	STP
C7-3	0.816	0.254	/	13.0	53.5	HRP
C7-21	0.738	0.213	/	10.0	44.5	HLP
C7-4	0.511	0.153	/	16.0	25.4	HLP
C7-5	0.377	0.109	/	19.0	14.1	HLP
C7-22	0.563	0.093	Microcrack	9.0	40.8	UM

Note: STP, HRP, HLP, and UM represent similar amplitudes of the two peaks, higher right peak and lower left peak, higher left peak and lower right peak, and unimodal distribution, respectively.
