Embodiment Construction
[0080] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0081] The embodiment of the present invention provides a reservoir classification method based on rock-electricity parameters. On the basis of the derivation of the existing rock-electricity experimental theoretical model, the theoretical range and range of theoretical values of rock-electricity experimental data under different pore structures are formed. Finally, the reservoir pore structure partitions on the F-Ф chart of lithoelectric data are formed. On this basis, using the logging data widely collected in oilfield production, combined with rock electrical experiment data and mercury intrusion capillary pressure curve data, the rock electrical method quantitative classification evaluation basis for common complex sandstone reser...
