Embodiment Construction
[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.
[0037] In view of the fact that the volumetric fracturing of tight oil is controlled by two dimensions of macroscopic and microscopic and three stages before pressure, during fracturing, and after fracturing, and each stage involves the characteristics of multi-factor control, the embodiment of the present invention provides a tight oil Multi-stage and multi-dimensional evaluation methods for volume fracturing effects, such as figure 1 As shown, the method includes:
[0038] Step 101: Acquiring the microcosmic fracability parameters before fracturing and the macrocos...
