A simulation device for experiment of underground water-sealed oil depot

Abstract

The invention relates to the field of oil depot simulation experiments, in particular to a simulation device for underground water-sealed oil depot experiments, comprising an oil storage chamber fixed on the inner bottom surface of an outer water tank, and an elevating mechanism for raising or lowering by using buoyancy is arranged on the inner bottom surface of the oil storage chamber. A hanging plate is fixed on the lifting mechanism, and the lower surface of the hanging plate is provided with a wave-proof mechanism that hinders the generation of ripples, and the lifting mechanism is provided with an adjustment mechanism for adjusting the contact between the wave-proof mechanism and the oil liquid surface. This kind of simulation device for underground water-sealed oil depot experiments makes the whole experimental simulation device suitable for underground water-seal storage experiments of different oil products, can accurately measure experimental parameters, obtain accurate experimental data, and obtain parameters that are more in line with actual conditions The variable relationship among them is beneficial to the construction and precise monitoring of underground water-sealed oil depots.

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
