Embodiment 1
[0048] This example provides a quantitative analysis method for pore volume increment of different scales of hydrated shale, and the specific steps are as follows:
[0049] 1. Determination of water and absolute ethanol T per unit mass (1g) by nuclear magnetic resonance 2 Spectrum, T 2 The spectrum signal amplitude values are 915 and 1182 respectively, and the conversion coefficient of the two is determined to be 1:1.3; the signal quantities corresponding to absolute ethanol and water in a calibrated unit volume (1mL) are S 1 and S 2 . In this experiment, the signal quantities corresponding to a unit volume of absolute ethanol and water are respectively S 1 = 24472 and S 2 =28623.
[0050] 2. Prepare standard rock samples in the target shale area by wire cutting. In this example, the shale rock samples come from three different shale gas wells in the Yongchuan area of western Chongqing, respectively labeled 1#, 2#, 3#, rock The sample size is Φ25×50mm. Then dry the ...
