Many large underground caverns in China will adopt a multi-stage construction method, and the expansion of underground caverns may have a certain impact on the seepage field of similar caverns near operation, potentially leading to a series of safety accidents such as oil and gas leakage. Therefore, ensuring the safety of the water seal after expansion is of critical importance.
In this paper, aimed at addressing this problem, the geological conditions and fracture distribution characteristics of the reservoir site area are analyzed based on a large underground cavern expansion project. Considering the joint dense zone connecting the two-stage caverns, and based on the field hydrological test results, the equivalent opening of the fracture is inverted. A simplified model of the two-stage underground caverns is then established using the random fracture network (DFN) approach. The water seal safety of the expanded underground caverns is studied, along with the influence of the expanded caverns on the water seal safety of the operating caverns.
The research shows that the expanded caverns have no effect on the water seal safety of the operating caverns, but the joint dense zone will seriously affect the water seal safety of the expanded caverns. Through the study of the influence factors of the expansion of the oil depot on the water seal safety of the adjacent operating oil depot, it is determined that the minimum safety distance between the caverns is 200 m, and the vertical and horizontal water curtain pressures are set to 0.4 MPa. These settings can guarantee the water seal safety of both the expanded and operating caverns.
Therefore, for large-scale underground cavern expansion projects, the joint dense zone is the key factor affecting water seal safety. Ensuring a minimum safety distance and appropriate water curtain pressure can effectively ensure the safety of both the expanded and operating caverns. The results provide a theoretical basis for studying water seal safety in the expansion of large underground caverns.
