Description

Technical Field

[0001] The invention belongs to the technical field of special tools for oil fields, and in particular relates to a crude oil decondensation device for measuring oil in an oil storage tank. Background Art

[0002] Due to the low temperature in winter, and the fact that the oil measuring pipes and instrument pipes on the oil storage tanks in the oilfield joint station have no heating facilities and are exposed to the air, the oil at the top of the oil measuring pipe is prone to condensation and forms an oil condensate cover, which can usually reach a thickness of 50 cm. Therefore, sampling and measuring operations cannot be completed, and measurement errors are prone to occur, resulting in inaccurate data. The same is true for the instrument pipe. When the liquid level is stable, the oil at the top is prone to condensation into an oil condensate cover, causing errors and false alarms in the values ​​measured by the radar level meter. If the oil condensate cover in the oil measuring pipe and instrument pipe is not dissolved in time, it will cause production data errors, which may easily lead to production accidents such as tank overflow and vacuum.

[0003] When the oil condensation cap appears in the oil measuring pipe and the instrument pipe, the commonly used method is to tie a rope to the copper hammer, and the staff stand on the top of the oil storage tank and use the rope to put the copper hammer into the oil measuring pipe or the instrument pipe, and then pull the rope up and down to use the copper hammer to smash through the oil condensation cap, and pour hot water from the oil inlet hole into the oil measuring pipe or the instrument pipe to melt the oil condensation cap. However, due to the large force area of ​​the copper hammer, it is not easy to smash the oil condensation cap, so it is still necessary to operate it by several strong staff members. At the same time, the hot water will be blocked by the oil condensation cap above the oil measuring pipe or the instrument pipe, and the heat acting on the oil condensation cap is less, and the heat dissipates faster. At the same time, the staff repeatedly goes up and down the oil storage tank and pulls the copper hammer, which will increase the labor intensity and low work efficiency. The oil condensation cap in the oil measuring pipe or the instrument pipe is not easy to melt completely, and it is easy to accumulate water, thereby causing false liquid level, which seriously affects the normal production and operation of the joint station. Summary of the invention

[0004] In order to solve the above problems, the object of the present invention is to provide a crude oil decondensation device for measuring oil in an oil storage tank.

[0005] In order to achieve the above-mentioned purpose, the oil storage tank measuring crude oil decondensation device provided by the present invention includes a container, a hanging ear, a water injection port, a sealing cover and a pulling rope; wherein, the upper part of the container is cylindrical, the bottom is inverted cone shape, and a water injection port is provided in the middle of the top surface; the sealing cover is threadedly connected to the water injection port; the two hanging ears are respectively connected to the upper two sides of the container; the lower ends of the two pulling ropes are respectively tied to the two hanging ears, and the upper part is held by the staff.

[0006] The container is made of brass material, with an upper height of 500 mm, a diameter of 100 mm, and a bottom height of 200 mm.

[0007] The water injection port is in the shape of a circular ring with a height of 50 mm and a diameter of 50 mm.

[0008] The pulling rope is made of antistatic material.

[0009] The oil storage tank oil measuring crude oil decondensation device provided by the present invention has the following beneficial effects:

[0010] The device is simple to manufacture, economical and practical, safe and convenient to use, meets the safety use standards, and has the characteristics of fast heat transfer. The inverted cone design at the bottom of the container can increase the pressure. The heat emitted by the hot water in the container can easily penetrate the condensed oil, and has the function of preheating and penetrating the condensed oil. The hot water is always in the container, the heat dissipation is slow, the thermal energy utilization rate is high, and hot water will not accumulate in the oil measuring pipe or instrument pipe, which can prevent the problem of false liquid level.
