Nghiên cứu đặc tính biến dạng và độ bền của muối đá dưới các áp lực bao kín khác nhau
Tóm tắt
Đặc điểm biến dạng và độ bền của muối đá là rất quan trọng đối với sự an toàn trong việc lưu trữ năng lượng hydrocarbon (dầu, khí) trong các hang muối. Để khắc phục vấn đề xác định độ bền cực đại bằng cách cân nhắc đồng thời các đặc tính pha loãng của đá muối, các thí nghiệm nén đã được thực hiện trên đá muối Pingdingshan dưới các áp lực bao kín khác nhau. Kết quả cho thấy thí nghiệm nén đơn trục của đá muối thể hiện sự phá vỡ giòn, nhưng sự hiện diện của tạp chất đã cải thiện độ bền của các mẫu. Sau khi ứng suất bao kín đạt đến "áp lực chuyển tiếp"—6.55 MPa, được xác định bằng cách sử dụng phương pháp biểu đồ, độ bền của đá muối tăng lên đáng kể và xuất hiện hiện tượng tăng cường biến dạng mạnh. Một phương pháp thực nghiệm để xác định "áp lực chuyển tiếp" đã được đưa ra, và cũng đã đề xuất rằng áp lực hoạt động tối thiểu trong một hang lưu trữ khí muối nên cao hơn giá trị này. Các thí nghiệm dưới các áp lực bao kín khác nhau chỉ ra rằng áp lực bao kín cao hơn thì hiện tượng pha loãng xảy ra càng nhiều. Dựa trên kết quả này, một phương pháp để xác định độ bền cực đại của đá muối dựa trên một giá trị biến dạng trục nhất định (6%) hoặc điểm khởi đầu của pha loãng đã được đề xuất. Sau đó, độ bền cực đại của các mẫu đá muối trong nghiên cứu này đã được tính toán để xác minh tính khả thi của phương pháp này. Nghiên cứu này đã cung cấp các phương pháp xác định "áp lực chuyển tiếp" và độ bền cực đại cho đá muối, làm cơ sở tham khảo cho việc đánh giá và vận hành các hang lưu trữ khí muối.
