【Abstract】 Introduces geological formation for building nature gas storage. Sets forth the rock body for storage building, its major structural face distribution and ground stress distribution behavior. Analyzes the problem effecting on the stability of storage and reliability of water sealing condition. Taking propane and butane storage for example, it states that the pressure of underground water must be higher than that of the product stored. Evaluates storage’s applicable prospect and economic profit aiming at its characteristics.更多还原
