Embodiment 1

[0074] In order to make the technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings. It should be noted that what is disclosed below is only a preferred embodiment of the present invention. Of course, the scope of rights of the present invention cannot be limited by this. Without departing from the principle of the present invention, those skilled in the art can also make some improvements and modifications, and these improvements and modifications should also be regarded as the protection scope of the present invention.

[0075] In order to simplify the description, in this example, a vertical water curtain is arranged around the cavern, which is used to evaluate and optimize the experimental device of the water curtain water sealing effect under different engineering geological conditions, including the stratum model 22 for simulating the actual engineering...

Embodiment 2

[0090] The device of the present invention is used as an experimental device for the feasibility study of island oil storage. The groundwater simulation device is filled with salt water to simulate the erosion of seawater on the underground storage (sea island oil storage), and then the salt content is set at the drain pipe 11. Measuring meter to monitor its salinity, connect the salinity measuring meter to the data acquisition center, when similar materials around the cavern are buried, other monitoring means can be arranged to monitor the seawater migration path, and simulate the resistance of the water curtain to seawater; in groundwater simulation In the device, the height of the water head in the formation model is changed, the influence of different seawater pressures on the cavern is simulated, the closure of the water curtain hole is adjusted, and the spatial layout of the water curtain is changed.

[0091] The invention provides an experimental device for judging and o...

Abstract

The invention discloses an experimental device and method for simulating water curtain water seal effects under different engineering geological conditions. The experimental device comprises a geological layer model, a water supply device and a data acquisition device. The geologic layer model includes a water tank; a cavern and an underground water simulation device are arranged at the bottom inthe water tank; and the water tank is filled with a simulated geologic layer material, wherein the geologic layer material and a simulated object material meet similar conditions. The underground water simulation device includes a water curtain pipeline arranged around the cavern; a water permeable holes are formed in the water curtain pipeline; a water curtain pipeline water inlet is communicatedwith a water supply device; a waterproof layer and a drainage structure are arranged at the bottom of a valve cavity arranged between the water supply device and the water curtain pipeline inlet; anda flow meter is arranged at the outlet of the drainage structure. A distributed fiber sensor, a stress and strain sensor and the flow meter are connected with a data acquisition center. According tothe invention, simulated data close to the reality are provided for analyzing the water curtain water seal effects under different engineering geological conditions and thus a reference design is provided for the engineering.

Description

technical field [0001] The invention belongs to the technical field of oil storage in underground caverns, and in particular relates to an experimental device and method for simulating the effects of water curtains and water seals under different engineering geological conditions. Background technique [0002] As an important strategic resource of the country, oil holds the lifeline of the national economy, and oil reserves have an important impact on a country's security and policy formulation. The underground water-sealed oil depot technology is favored by various countries due to its advantages of large capacity, high safety, and good concealment. In the process of storing oil in underground caverns, in order to ensure that the oil does not leak and ensure its safe operation, higher requirements are put forward for its water sealing. In the oil storage cavern projects that are currently under construction or in operation in my country, the research on the water sealing p...
