Fracability Evaluation Method of a Fractured-Vuggy Carbonate Reservoir in the Shunbei Block. [PDF]
The fracability of carbonate reservoirs is a key indicator for evaluating whether reservoirs can be effectively fractured. Taking the fractured-vuggy carbonate reservoir in the Shunbei block as an example, the microscopic characteristics and mechanical properties of this reservoir were analyzed.

Experimental Study on Viscosity-Reducing Foam Flooding in Fractured-Vuggy Reservoirs. [PDF]
The crude oil reserves of fractured-vuggy reservoirs are large, but most of them are heavy oil and ultraheavy oil reservoirs. They have the characteristics of high heavy metal ion concentration, high asphaltene content, high viscosity and density, and deep burial. They are difficult to exploit.

Analysis of the Influencing Factors on the Extraction of Residual Oil through the Gel Foam Flooding of Underground Reservoirs in the Tahe Oilfield [PDF]
Fractured-vuggy reservoirs are mainly composed of three types: underground rivers, vugs, and fractured-vuggy structures. Based on the similarity criterion, a 3D model can truly reflect the characteristics of the multi-scale space of a fractured-vuggy ...
