TABLE 2 comparison of oil loss between the oil storage tank of the present example and the oil storage tank of the prior art
From table 2, it can be derived: the oil consumption of the oil storage tank 10 in this embodiment is significantly less than that of the oil storage tank in the prior art, and the oil consumption is reduced to a greater extent.
As shown in fig. 2, the oil tank 10 has a first oil inlet 12, the oil tank 70 has a first oil outlet 71, and the test system for reducing breathing loss of the oil tank further includes a first oil path 90. Wherein, the first oil outlet 71 is communicated with the first oil inlet 12 through a first oil path 90. Wherein, the first oil inlet 12 is higher than the first oil outlet 71. Thus, the oil in the oil tank 70 passes through the first oil outlet 71 and enters the oil storage tank 10 through the first oil passage 90, so that the oil in the oil storage tank 10 is dynamically circulated.
As shown in fig. 2, the oil storage tank 10 further has a second oil outlet 13, the oil tank 70 has a second oil inlet 72, and the test system for reducing breathing loss of the oil storage tank further includes a second oil path 100. Wherein, the second oil outlet 13 is communicated with the second oil inlet 72 through a second oil path 100. The height position of the second oil inlet 72 is higher than the height position of the second oil outlet 13, the height position of the first oil inlet 12 is higher than the height position of the second oil outlet 13, and the height position of the second oil inlet 72 is higher than the height position of the first oil outlet 71. Thus, the oil in the oil tank 10 passes through the second oil outlet 13 and enters the oil tank 70 through the second oil passage 100, so that the oil is communicated between the oil tank 70 and the oil tank 10. Meanwhile, the above-mentioned height position relationship between the second oil inlet 72 and the second oil outlet 13 ensures that the oil in the oil storage tank 10 can enter the oil tank 70 only when the oil pressure in the oil storage tank 10 is relatively high.
Specifically, the oil in the oil tank 70 can enter the oil storage tank 10 through the first oil outlet 71 and the first oil inlet 90 and 12, and the oil in the oil storage tank 10 can enter the oil tank 70 through the second oil outlet 13 and the second oil inlet 100 and 72, so as to realize the oil circulation between the oil tank 70 and the oil storage tank 10 and the dynamic balance of the oil in the oil storage tank 10.
As shown in fig. 2, the test system for reducing breathing loss of the storage tank further includes an oil pump 110. The oil pump 110 is disposed on the first oil path 90, so that oil discharged from the first oil outlet 71 enters the first oil inlet 12 through the first oil path 90 by the oil pump 110. Thus, only after the oil pump 110 is started, the oil in the oil tank 70 can enter the oil storage tank 10 through the first oil path 90, and the controllability of the oil in the test system is further realized. Optionally, the pump 110 is a high precision stainless steel gear pump. The type of the oil pump 110 is not limited to this, as long as the oil pump can function to pump oil.
In this embodiment, the above-mentioned consumption reduction measures of the test system can be directly applied to the storage tank in the oil field, so that the small breathing loss of the storage tank can be reduced by more than 70% on the original basis. Therefore, the test system in the embodiment can reduce oil loss, save energy, reduce consumption, improve the comprehensive benefits of oil field development and reduce the influence of oil gas emission on the environment.
From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects:
and a heat insulation coating is arranged on the outer wall of the oil storage tank. When the oil storage tank is in the initial state, the oil storage tank and oil in the oil storage tank are weighed by the first weighing device, so that a first initial weighing value is obtained. After the initial state is carried out for a preset time, the first weighing device weighs the oil storage tank and oil in the oil storage tank again to obtain a loss weighing value, and the loss weighing value is differed from the first initial weighing value to obtain an oil loss amount. Like this, can obtain the oil consumption volume of the oil storage tank after scribbling and establish thermal barrier coating through the test system who reduces the oil storage tank breathing loss, and then solved among the prior art problem that can't accurately acquire crude oil consumption volume.
