The invention provides a water curtain system optimization design method based on a water seal action mode. The method comprises the following steps: (1) evaluating surrounding rock cracks of a watercurtain roadway; (2) selecting a water curtain drilling hole distribution target area; (3) performing a transient electromagnetic test on the roadway section; (4) performing a single water curtain drilling hole water injection test; (5) performing new classification of water curtain drilling holes, specifically, the water curtain drilling holes are divided into five types, namely type I to type V;and (6) for the water curtain drilling holes of types I to IV, respectively performing replenishment function evaluation and water cap rock function evaluation and performing replenishment construction of water curtain drilling holes in an area which cannot meet requirements, and performing grouting treatment on the water curtain drilling holes of type V. By adopting the method provided by the invention, it can be ensured that new classification of the water curtain drilling holes is performed through drilling flow-pressure change characteristics on the basis of meeting the reliability of water seal, the state of rock mass in a region where the drilling holes are located can be taken into consideration, and the purpose of realizing the best water seal effect by using the minimum number ofwater curtain drilling holes is achieved.
Description
technical field [0001] The invention relates to the technical field of underground water-sealed caverns, in particular to an optimal design method for a water curtain system based on a water-sealed action mode. Background technique [0002] Underground water-sealed cavern is a kind of oil storage method commonly used in my country at present, which has the advantages of safety, environmental protection, low cost and environmental friendliness. The water curtain system is the core component of the underground water-sealed cavern, and its function is to ensure the safety of the water seal in the entire life cycle of the cavern. In the cavern design, the design of the water curtain system (design parameters such as water curtain drilling spacing, length, water curtain roadway layout, etc.) usually adopts a unified standard. However, due to the complexity of the distribution of cracks in the rock mass, this unified design may cause some drilling holes to be in complete rock mas...
