Description

Technical Field

[0001] This utility model relates to the field of density testing equipment technology, and in particular to a device for detecting lightweight agents. Background Technology

[0002] Lightening agents are additives used to reduce the density of cement slurry. In the preparation of cement for oil drilling operations, simply adding extra water to reduce the cement density can cause cement particles to sink, or excess free water to accumulate during the cement setting process, affecting the cement's sealing properties. Adding a lightening agent to the cement, characterized by its low density and high water absorption, allows it to absorb excess free water in the cement slurry, thus ensuring the cement's sealing. Different densities of lightening agents need to be selected when preparing cement slurry of different qualities; therefore, testing the density of the lightening agent is a necessary step in cement slurry preparation. However, existing solid density testing devices disclosed in applications with publication numbers CN209784120U, CN219532808U, and CN222482053U require the solid to be completely immersed in the testing water, i.e., the density of the object being tested must be greater than 1 g / cm³. 3 Such devices are not suitable for densities less than 1 g / cm³. 3 Testing of lightweighting agent materials.

[0003] In summary, the goal is to develop a method capable of detecting densities less than 1 g / cm³. 3 A density detection device for weight-reducing agents is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a lightening agent detection device that solves the technical problem that existing density detection devices cannot detect lightening agents with a density less than water.

[0005] To achieve the above objectives, this utility model provides a weight-reducing agent detection device, comprising:

[0006] Preferably, the test bottle contains test water and a lightening agent. The inner cavity of the test bottle is provided with a stopper that fits against the inner wall of the test bottle. The stopper is used to prevent the lightening agent from floating. The stopper has several holes, allowing the test water to permeate the stopper. The stopper is connected to a pull rope, which is used to remove the stopper from the port of the test bottle. A sealing plug is provided at the port of the test bottle to seal the port of the test bottle.

[0007] Preferably, the pull rope passes through the stopper along its axis, and a gasket is provided at the end of the stopper away from the sealing plug. The gasket is connected to the pull rope and is used to apply thrust to the stopper.

[0008] Preferably, the gasket has a connecting hole at its center, through which a pull rope passes. The end of the pull rope has a retaining member with a diameter larger than that of the connecting hole. The retaining member abuts against the side of the gasket facing away from the stopper.

[0009] Preferably, the port of the test bottle is provided with a guide portion, the diameter of which increases toward the side away from the stopper.

[0010] Preferably, the test bottle is made of a transparent material, and the side wall of the test bottle is provided with an indicator scale.

[0011] Preferably, a limiting member is provided at the end of the sealing plug away from the stopper, the length of the sealing plug is equal to the distance from the indicator scale to the port of the test bottle, and the diameter of the limiting member is greater than the diameter of the port of the test bottle.

[0012] Preferably, the stopper is made of sponge material, and the gasket is made of either hard cotton cloth or hard plastic.

[0013] Compared to the aforementioned background technology, the lightweight agent detection device provided by this utility model includes: a detection bottle for containing the lightweight agent to be tested and testing water; a stopper is provided inside the neck of the detection bottle, the stopper is fitted against the inner wall of the detection bottle, the stopper has several holes, and the testing water can wet and pass through the stopper; the stopper is positioned above the lightweight agent to be tested; a sealing plug is provided at the port of the detection bottle, the sealing plug closes the port of the detection bottle; in addition, the stopper is connected to a pull rope; when performing lightweight agent density testing, a certain volume of testing water is placed in the same detection bottle and the mass of the device at this time is recorded; subsequently, a specified mass of lightweight agent is added to the detection bottle, and two tests are performed. When the liquid level in the test bottle reaches the same mark, the difference between the mass of the apparatus and the mass of the lightening agent in the second test is calculated. Subtracting this difference from the mass of the apparatus obtained in the first test yields the mass of the test water of the same volume as the lightening agent. Since the mass and density of the test water are known, the density of the lightening agent can be determined after detecting its volume. This application uses a stopper to prevent the lightening agent from floating. Test water is poured over the stopper, allowing it to pass through and completely wet the lightening agent. This method can accurately obtain the volume of a specified mass of lightening agent, enabling this application to detect lightening agents with a density less than water, i.e., suitable for those with a density less than 1 g / cm³. 3 The testing of the lightweighting agent material also ensures that the testing device has sufficient accuracy.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] This utility model provides a device for detecting lightweighting agents; please refer to the appendix to the instruction manual. Figure 1 The testing device includes a test bottle 1 for containing the water to be tested 6 and the lightening agent 7. It should be noted that the density of the lightening agent 7 is less than the density of the water to be tested 6, that is, the lightening agent 7 floats above the water to be tested 6. A stopper 2 is provided inside the neck of the test bottle 1. The stopper 2 has several holes. The side wall of the stopper 2 fits against the inner wall of the neck of the test bottle 1, and the stopper 2 can be soaked in the water to be tested 6. Placing the stopper 2 above the lightening agent 7 can limit the floating of the lightening agent 7. Furthermore, the stopper 2 is connected to a pull rope 3. By pulling the pull rope 3, the stopper 2 placed in the test bottle 1 can be removed. In addition, a sealing plug 5 is also inserted at the port of the test bottle 1 to seal the water to be tested 6, the lightening agent 7 and the stopper 2 inside the test bottle 1 to prevent the water to be tested 6 or the lightening agent 7 from splashing out of the test bottle 1 during the testing process.

[0020] In the process of using this invention to test the density of a lightening agent, a certain volume of test water 6 is injected into the cleaned test bottle 1. Injection is stopped when the level of the test water 6 reaches a certain distance below a designated mark. A stopper 2, pre-wetted in the test water 6, is then inserted into the test bottle 1, with the upper end of the stopper 2 below the designated mark. It should be noted that the stopper 2 can be inserted by pressing it with a glass rod. After installation, the stopper 2 may partially block air bubbles from below. The operator can use a glass rod to press it down. Pressing the stopper 2 causes air bubbles to escape from its porous structure. Then, continue injecting test water 6 into the test bottle 1 until the water level reaches the designated mark, ensuring the stopper 2 is completely submerged. After installing the sealing plug 5 at the bottle opening, weigh the test bottle 1 and record the mass as m1. Then, remove the sealing plug 5 and stopper 2 in sequence, and pour out a portion of the test water 6 from the test bottle 1, leaving sufficient space to accommodate the reducing agent 7. The operator weighs the designated mass (m3) of the reducing agent 7 and... Lightweight agent 7 is placed into test bottle 1, and stopper 2 is placed above the lightweight agent 7. Then, test water 6 is poured in. Because the density of test water 6 is greater than that of lightweight agent 7, during the pouring process, lightweight agent 7 gradually floats to the surface until it touches the stopper 2. Afterward, lightweight agent 7 stops floating while the level of test water 6 continues to rise, completely immersing lightweight agent 7 in the test water 6. The operator shakes test bottle 1 to ensure thorough mixing of the test water 6 and lightweight agent 7, preventing any residue of lightweight agent 7 from remaining. Air caused a deviation in the mass of the test water 6 displaced by the reducing agent 7. Subsequently, test water 6 was continuously injected until the liquid level reached the designated mark again. The test bottle 1 was weighed at this point, and the mass was recorded as m2. Since the volume of the test water 6 without reducing agent 7 in the first pour was the same as the volume of the mixture with reducing agent 7, the operator subtracted m3 from m2 to obtain the mass of the second pour of test water 6. This difference was then subtracted from m1 to obtain the mass of the test water 6 displaced by the reducing agent 7. The density of the test water 6 (ρ) was then calculated. 水 Given that the volume of the lightening agent 7 is known, its density (ρ) can be obtained from the volume and mass of the lightening agent 7.

[0021] Preferably, a pull rope 3 is threaded inside the stopper 2, and the pull rope 3 passes through the stopper 2 along its axis. A gasket 4 is provided at the end of the stopper 2 away from the port of the test bottle 1, and a connecting hole is provided at the center of the gasket 4. The pull rope 3 passes through the stopper 2 and also through the connecting hole. Furthermore, a support member 31 is connected to the end of the pull rope 3 that passes through the gasket 4. The diameter of the support member 31 is larger than the diameter of the connecting hole. When the operator pulls the pull rope 3, the support member 31 at the end of the pull rope 3 abuts against the edge of the connecting hole, and the support member 31 applies an upward pushing force to the gasket 4. The gasket 4 pushes the stopper 2 out of the test bottle 1. The pull rope 3 drives the gasket 4, so that the lower end of the stopper 2 is evenly stressed. If the pull rope 3 is directly connected to the stopper 2, the thinner pull rope 3 can only pull part of the stopper 2, causing the stopper 2 to deform and easily damage the stopper 2, affecting the reliability of the testing device.

[0022] Please continue to refer to the instruction manual appendix. Figure 1 A guide is connected to the port of the test bottle 1. Preferably, the diameter of the guide increases towards the end away from the stopper 2, making the port of the test bottle 1 funnel-shaped, which makes the process of pouring the test water 6 more convenient. In addition, the operator can place the lightening agent 7 in the guide beforehand, and then pour the test water 6. The test water 6 will flush the lightening agent 7 into the test bottle 1, making it easier for the solid lightening agent 7 to be transferred into the test bottle 1. At the same time, the test water 6 accelerates the mixing of the two during the flushing process of the lightening agent 7.

[0023] Preferably, a limiting member 51 is provided at the end of the sealing plug 5 away from the stopper 2. The diameter of the limiting member 51 is larger than the diameter of the port of the test bottle 1. The limiting member 51 is used to prevent the sealing plug 5 from extending too far into the port, which would make it difficult to remove the sealing plug 5 from the test bottle 1. Furthermore, an indicator scale is provided at a certain distance below the port of the test bottle 1. During the process of injecting the test water 6, the operator uses this indicator scale as a reference to avoid different liquid levels of the test water 6 after two injections. In addition, the length of the sealing plug 5 is equal to the distance from the port of the test bottle 1 to the indicator scale. When the liquid level in test bottle 1 does not reach the indicated mark, some air bubbles are trapped between the sealed plug 5 and the liquid surface. The operator can further judge whether the liquid level has reached the specified mark by observing whether there are air bubbles on the liquid surface. However, when the test water 6 exceeds the indicated mark, the sealed plug 5 cannot be completely inserted. The operator can feel that the sealed plug 5 is easy to shake when inserting it, prompting the operator to check the liquid level. This further ensures that the volume in test bottle 1 is the same in the two tests. After subtracting the mass, the mass of test water 6 with the same volume as the reducing agent 7 can be accurately obtained.

[0024] Preferably, the test bottle 1 is made of a transparent material, which allows the operator to easily observe the liquid level inside the test bottle 1 and the mixing of the lightening agent 7 and the test water 6. The test bottle 1 can be a Leigh density bottle. In addition, the sealing plug 5 can be made of sponge material with a large number of micropores, which allows the test water 6 to pass through while preventing the lightening agent 7 particles from passing through the stopper 2. The gasket 4 can be made of either hard plastic or hard cotton cloth to ensure that the gasket 4 can provide sufficient support for the stopper 2.

[0025] In one embodiment of this application, the stopper 2 is placed in a beaker containing test water 6 and thoroughly moistened. The sample is weighed using an electronic balance, and test water 6 is added to the test bottle 1. The sponge stopper 2 is placed 2 to 4 cm away from the port of the test bottle 1 and gently pushed in with a glass rod so that it is below the indicator scale. Water is then added to the indicator scale and air bubbles are removed. The stopper 2 and the sealing plug 5 are tightly sealed. Excess water is wiped off, and the weight is recorded as m1. During the second weighing, the sealing plug 5 is removed, and the stopper 2 is pulled out and placed in the beaker using the pull rope 3. Some of the test water 6 in the test bottle 1 is poured out, and the lightening agent 7 is added. The test bottle 1 is then shaken to fully moisten the lightening agent 7. Next, continue adding test water 6 until the liquid level reaches 2 to 4 cm from the port of test bottle 1. Then, use a glass rod to push down the stopper 2 to prevent the lightening agent 7 from floating. Continue adding test water 6 to fill the bottle, remove air bubbles, tighten the sealing stopper 5, wipe off excess water, weigh and record the weight as m2. Calculate the density of the lightening agent based on the fact that the volume is the same before and after adding the lightening agent.

[0026] By using a porous material stopper 2, the liquid volume in the test bottle 1 is completely the same before and after the addition of the lightening agent 7, making m1 a quantitative measure. This overcomes human error and instrument error, making the operation more convenient and the test results more accurate.

[0027] The formula for calculating the density of the lightening agent is as follows:

[0028] , ρ 水 To test the density of the water, m1 is the mass of the test bottle with only the test water added, m2 is the mass of the test bottle after adding the lightening agent and the test water, and m3 is the mass of the lightening agent weighed.

[0030] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
