Simulation device for underground water-sealed oil depot experiments

Abstract

The invention relates to the field of oil depot simulation experiments, and in particular to a simulation device for underground water-sealed oil depot experiments. The device comprises an oil storagechamber fixed to the inner bottom face of an outer water tank, a lifting mechanism ascending or descending through buoyancy is arranged on the inner bottom face of the oil storage chamber, a hangingplate is fixed to the lifting mechanism, a wave preventing mechanism for preventing corrugations from being generated is arranged on the lower surface of the hanging plate, and an adjusting mechanismfor adjusting the wave preventing mechanism to make contact with the liquid level of oil is arranged on the lifting mechanism. According to the simulation device for an underground water-sealed oil depot experiment, the whole experiment simulation device can be suitable for underground water seal storage experiments of different oil products, experiment parameters can be accurately measured, accurate experiment data are obtained, and therefore the variable relation between the parameters better meeting the actual situation is obtained, and construction and accurate monitoring of an undergroundwater seal oil depot are facilitated.

Description

technical field [0001] The invention relates to the field of oil depot simulation experiments, in particular to a simulation device for underground water-sealed oil depot experiments. Background technique [0002] Underground water-sealed oil depot, as a new type of underground oil storage method, has the advantages of safety, reliability, large oil storage capacity and low environmental pollution. [0003] In order to study the water sealing principle of the underground oil depot and the influence of various parameters, the patent application number 201711283165.4 discloses a test device and method for simulating the water sealing effect of the underground cavern, which measures the oil storage volume, The variable relationship between the groundwater level and the water curtain pressure, in which during the parameter adjustment process of the oil storage volume, the fluctuation of the oil liquid is affected by the oil filling operation and the suction operation, so the int...

[0003] In order to study the water sealing principle of the underground oil depot and the influence of various parameters, the patent application number 201711283165.4 discloses a test device and method for simulating the water sealing effect of the underground cavern, which measures the oil storage volume, The variable relationship between the groundwater level and the water curtain pressure, in which during the parameter adjustment process of the oil storage volume, the fluctuation of the oil liquid is affected by the oil filling operation and the suction operation, so the internal stress of the oil liquid will be generated, which will lead to The side walls on both sides of the oil storage chamber are subjected to different pressures, so that the depth of the oil in the oil storage chamber seeping out from the side wall of the oil storage chamber is not balanced with the depth of the external water liquid penetrating into the side wall of the oil storage chamber , so that it is not convenient to observe the variable relationship among the oil storage, groundwater level and water curtain pressure in the experiment of the control variable method. In view of this, we propose a simulation device for the experiment of underground water-sealed oil depot
