Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas field development, in particular to a portable oil-water interface instrument. Background Art

[0002] Crude oil dehydration relies on the density difference between oil and water. Physical sedimentation can remove most of the free water. An oil-water interface will be formed during the sedimentation separation process. Controlling the height of the oil-water interface is one of the important parameters that affect the dehydration effect of the sedimentation tank. It is required to accurately master it during the production process so that the parameters can be adjusted in time. Only a few sedimentation tanks are installed with oil-water interface meters at the production site, and there are many problems such as high failure rate and large errors during use. During the manual proofreading and measurement process, it is necessary to use a sampler to take samples multiple times, and estimate the height of the oil-water interface by observing the water content.

[0003] In the prior art, a portable oil-water interface meter with a publication number of "CN2862025Y" uses a high-performance signal conditioning integrated circuit to improve measurement accuracy; a dual CPU is used to form a test system, which transmits in digital form and improves the reliability of the instrument; other sensors can be added to the probe, such as an additional temperature sensor for measuring temperature, and multi-parameter measurement can be achieved by adding very little hardware.

[0004] However, this method may still cause environmental pollution accidents during operation due to violent shaking of the ruler causing the sampler to fall and scattered samples during the sampling process. The sampler needs to be used for multiple sampling, which is time-consuming and labor-intensive. Utility Model Content

[0005] The embodiment of the utility model provides a portable oil-water interface meter to solve the problems that the oil-water interface meter in the prior art is prone to environmental pollution accidents during operation and requires the use of a sampler for multiple sampling, which is time-consuming and labor-intensive.

[0006] The embodiment of the utility model provides a portable oil-water interface meter, comprising a suspension device and a force measuring indicating device, wherein the suspension device is placed vertically, the force measuring indicating device is arranged above the suspension device, and the force measuring indicating device is used to display the mass of the suspension device in real time.

[0007] Optionally, the force indicating device includes a ruler frame, a dynamometer bracket and a dynamometer, wherein the dynamometer bracket is fixedly connected to the ruler frame, one end of the dynamometer is connected to the ruler frame, and the other end is connected to the dynamometer bracket.

[0008] Optionally, the force measuring indicating device further comprises a tape fulcrum and a tape, wherein the tape fulcrum is arranged at one end of the scale frame close to the dynamometer, the tape is arranged on one side of the scale frame close to the dynamometer bracket, and one end of the tape passes through the tape fulcrum and is connected to the suspension device.

[0009] Optionally, the force indicating device further comprises a handle, which is arranged at an end of the ruler frame away from the fulcrum of the ruler tape.

[0012] Optionally, the suspension device further comprises a hook, and the hook is arranged at one end of the suspension device close to the force measuring indicating device.

[0013] Optionally, the number of weights is 0, 1, or more.

[0014] Beneficial effects:

[0015] A portable oil-water interface meter provided in an embodiment of the present application displays the mass of a suspension device in real time through a force measuring indicating device. When the suspension device enters crude oil, buoyancy is generated and the displayed value of the force measuring indicating device becomes smaller. The suspension device continues to move downward and floats on the water surface. The buoyancy becomes larger and the indicated value of the force measuring indicating device further decreases. In this way, the operator can intuitively judge the position of the suspension device through the change of the indicated value, making the measurement result more accurate. There is no need to use a sampler for multiple sampling, which saves time and effort, and greatly avoids the sampler falling off due to severe shaking of the ruler and the phenomenon of scattered samples during the sampling process, thereby reducing environmental pollution generated during the measurement process.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] refer to Figure 1 An embodiment of the present application provides a portable oil-water interface meter, which includes a force measuring indicating device 1 and a suspension device 2, wherein the suspension device 2 is placed vertically, and the force measuring indicating device 1 is arranged above the suspension device 2, and the force measuring indicating device 1 is used to display the mass of the suspension device 2 in real time.

[0025] Specifically, the portable oil-water interface meter displays the mass of the suspension device 2 in real time through the force measuring indicating device 1. When the suspension device 2 enters the crude oil, buoyancy is generated, and the display value of the force measuring indicating device 1 becomes smaller. The suspension device 2 continues to move downward, and after floating on the water surface, the buoyancy becomes larger, and the indication value of the force measuring indicating device 1 further decreases. In this way, the operator can intuitively judge the position of the suspension device 2 through the change of the indication value, so that the measurement result is more accurate, and there is no need to use a sampler for multiple sampling, which saves time and effort, and greatly avoids the sampler falling due to violent shaking of the ruler and the sample scattering phenomenon during the sampling process, reducing the environmental pollution generated by the measurement process.

[0026] Furthermore, this exemplary embodiment adjusts the mass of the suspension device 2 according to the different densities of oil and water so that it can pass through the oil layer and float on the water surface, thereby achieving a one-time measurement and accurate measurement of the thickness of the oil layer, thereby achieving the purpose of measuring the oil-water interface.

[0027] In a possible implementation, the force indicating device 1 includes a ruler frame 4, a dynamometer bracket 7 and a dynamometer 8, wherein the dynamometer bracket 7 is fixedly connected to the ruler frame 4, one end of the dynamometer 8 is connected to the ruler frame 4, and the other end is connected to the dynamometer bracket 7, as shown in FIG. Figure 2 shown.

[0028] Specifically, the ruler frame 4 is modified from an oil measuring tooth, and the ruler frame 4 and the dynamometer bracket 7 jointly fix the dynamometer 8 , which is used to display the mass of the suspension device 2 .

[0029] In a possible implementation, the force indicating device 1 further includes a tape fulcrum 6 and a tape 3, wherein the tape fulcrum 6 is arranged at one end of the scale frame 4 close to the dynamometer 8, the tape 3 is arranged at one side of the scale frame 4 close to the dynamometer bracket 7, and one end of the tape 3 passes through the tape fulcrum 6 and is connected to the suspension device 2, as shown in FIG. Figure 2 shown.

[0030] Specifically, a tape fulcrum 6 is provided at one end of the scale frame 4 close to the dynamometer 8 to facilitate the tape 3 to pass therethrough, so that the force indicating device 1 can be connected to the suspension device 2 through the tape 3 .

[0031] In a possible implementation manner, the force indicating device 1 further includes a handle 5, which is disposed at one end of the ruler frame 4 away from the ruler tape fulcrum 6, so as to facilitate taking the portable oil-water interface meter. Figure 2 shown.

[0032] In a possible embodiment, the suspension device 2 includes a cabin 12 and a weight 13, wherein the cabin 12 is connected to one end of the tape 3 passing through the tape fulcrum 6, and the weight 13 is arranged inside the cabin 12, as shown in FIG. Figure 3 shown.

[0033] Specifically, the ideal state of the suspension device 2 during measurement is to pass through the oil layer and float on the water. In this way, the liquid displaced by the suspension device 2 is half water and half oil. The mixed density ρmix of the displaced medium is calculated, and a cabin 12 is processed into a ruler. The mass of the suspension device 2 is calculated using the buoyancy formula: G=ρmix×Vdisplaced. The mass of the suspension device 2 is changed by adding different numbers of weights 13 inside the cabin 12, so that it can pass through the oil layer and float on the water surface, thereby achieving the purpose of measuring the thickness of the oil layer and calculating the height of the oil-water interface.

[0034] In a possible implementation, the suspension device 2 further includes a sealing cap 10 and a sealing ring 11, wherein the sealing cap 10 is threadedly connected to the cabin body 12, and the sealing ring 11 is disposed between the sealing cap 10 and the cabin body 12. Figure 3 shown.

[0035] In this exemplary embodiment, the provision of the sealing cap 10 and the sealing ring 11 prevents water from entering the interior of the cabin 12, ensuring that the quality of the suspension device 2 is not affected by the outside world, so that the measurement result of the oil layer thickness is not affected, thereby ensuring that the calculation result of the oil-water interface height is accurate.

[0036] In a possible implementation manner, the suspension device 2 further includes a hook 9, which is disposed at one end of the suspension device 2 close to the force measuring indicating device 1. Figure 3 shown.

[0037] Specifically, the cabin 12 is connected to one end of the tape 3 passing through the tape fulcrum 6 via the hook 9, thereby realizing the connection between the force measuring indicating device 1 and the suspension device 2. Furthermore, the hook 9 can also be replaced by other connecting parts as long as the connection between the force measuring indicating device 1 and the suspension device 2 can be realized and will not fall off during use.

[0038] In one possible implementation, reference Figure 3 The number of weights 13 is 0, 1 or more. The mass of the suspension device 2 is changed by changing the number of weights 13, thereby changing the indication value of the force measuring indicating device 1.
