Abstract:

The pore structure of shale reservoirs has a very significant impact on shale gas reservoir. An atomic force microscope (AFM) has unique advantage in characterization of micro-nanoscale structure, and can reflect three-dimensional structure of the surface of a sample. For the study of the relationship between micro-nanometer pore characterization of shales and the amount of field analytical gas extracted from core, we choose typical samples of Jiaoye 1 well (JY1) and Yucan 4 well (YC4) from Fuling of Chongqing as research objects. We get the micro-structure characterization of the rock samples by atomic force microscope, by obtaining three-dimensional topographies of the samples, and by analyzing the features of pore distribution and reservoir space of the samples. We then build parameters that represent internal characteristics of rock samples. Having compared the differences of the characteristic parameters from different well sections in the same well, and the differences of characteristic parameters from different wells respectively, we describe the morphology features of the rock samples quantitatively. Combined with the data of field analytical gas, we build the relationship between the amount of field analytical gas and characteristic parameters of JY1 and YC4 samples, respectively. The results show that relative to the YC4 samples, JY1 samples show more intensive reservoir spacesis, and higher porosity, and more beneficial to the storage of gas. The results also show that there is a positive correlation between the fluctuation degree of interspace and the amount of the field analytical gas of JY1 and YC4 samples. Our results may have significance for the quantitative evaluation of the relation between exploitable volume and the micro-pore structure of shale gas.

Key words: shale, structure of the pores, analytical gas, atomic force microscope, characteristic parameters
