Embodiment Construction
[0044] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not used to limit the present invention.
[0045] figure 1 It shows the implementation process of the method for macro-quantification of remaining oil in different microscopic states provided by the embodiment of the present invention.
[0046] The method includes the following steps:
[0047] Step 1: Obtain the distribution field of remaining oil reserves and water saturation through macroscopic numerical simulation;
[0048] Step 2: Determine the range of underground water saturation under different water washing conditions according to the water washing degree classification standard and the original water saturation, and combin...
