[0001] The utility model belongs to the technical field of gel plugging agent gelation performance detection, and particularly relates to a device for detecting the gelation performance of a gel plugging agent. Background Art

[0002] Gel plugging agents are widely used in formation plugging operations such as profile control and water shutoff, and leakage plugging. In these operations, it is necessary to strictly control the gelation performance of the gel plugging agent, which determines whether the gel plugging agent can reach the target area smoothly.

[0003] At present, the detection method for the gelation performance of gel plugging agents mainly adopts the "bottle method", that is, the gel plugging agent is placed in a reagent bottle, the reagent bottle is sealed, and then placed in a water bath heating device to age the gel plugging agent by heating. During this process, the reagent bottle needs to be taken out and inverted at regular intervals. Thus, according to the gel visual code method, the gelation performance of the gel plugging agent is judged.

[0004] Although this method can effectively judge the gelation performance of the gel plugging agent, each time the reagent bottle is taken out for observation, the reagent bottle will be exposed to the air, affecting the temperature field inside the bottle. When the reagent bottle is put back into the water bath heating device, it takes a certain time to return to the original temperature. In this way, frequent observation of the gelation state will lead to inaccurate detection of the gelation time of the gel, slow detection results, and is not conducive to the study of gelation performance.

Detailed implementation mode

[0022] To better understand the purpose, structure and function of the present invention, the following further describes in detail a device for detecting the gelling performance of a gel plugging agent according to the present invention with reference to the drawings.

[0023] For convenience, the direction along the extension of the containing bottle is referred to as "vertical direction", "perpendicular direction" or similar terms, the direction perpendicular to the "axial direction" is referred to as "transverse direction", "horizontal direction" or similar terms, the direction from the bottom wall of the containing bottle to the sealing cap is referred to as "upward" or similar terms, and the direction from the sealing cap of the containing bottle to the bottom wall is referred to as "downward" or similar terms.

[0024] As Figure 1 shown, an embodiment of the present invention provides a device 100 for detecting the gelling performance of a gel plugging agent, including a containing bottle 1 for containing the gel plugging agent, and a heating mechanism 2 for placing the containing bottle 1 and capable of uniformly heating the containing bottle 1. Among them, the heating mechanism 2 includes a transparent box body 21 and a heater 22 arranged in the box body 21.

[0025] At the same time, the device 100 further includes a rotating mechanism 3 horizontally arranged in the box body 21 and used for vertically clamping the containing bottle 1, and the rotating mechanism 3 can drive the containing bottle 1 to rotate in the box body 21 along a direction perpendicular to the axis of the containing bottle 1.

[0026] In this setting, by applying a force to the rotating mechanism 3, the rotating mechanism 3 can drive the containing bottle 1 to rotate in the heating mechanism 2, so that the containing bottle 1 can be inverted. Specifically, the opening of the containing bottle 1 faces downward. At this time, the gel plugging agent located inside the containing bottle 1 will flow downward along the wall of the containing bottle 1. In this way, the staff can detect the gelling performance of the gel plugging agent according to the gel visual code method.

[0027] In one embodiment, as Figure 1 shown, the containing bottle 1 includes a bottom wall 11 and a side wall 12 arranged on the bottom wall 11 and extending vertically upward along the bottom wall 11. The bottom wall 11 and the side wall 12 together form a top-opening and internally hollow containing space for containing the gel plugging agent.

[0028] Among them, the bottom wall 11 is arranged in a circular structure, and the side wall 12 is arranged in a hollow circular tubular structure rising along the bottom wall 11. Since the side wall 12 rises vertically along the bottom wall 11, the top opening formed by the side wall 12 is equivalent to the diameter of the bottom wall 11. Thus, the hollow accommodation space is in a cylindrical shape.

[0029] In this way, when the accommodation bottle 1 is inverted, the gel plugging agent in the accommodation bottle 1 can move vertically downward along the side wall 12, making it more accurate for the staff to observe the flow state of the gel plugging agent according to the gel visual code method. It should be noted that the side wall 12 is made of any transparent material. In this way, when the accommodation bottle 1 contains the gel plugging agent, the staff can observe the state of the internal gel plugging agent in the accommodation bottle 1 through the side wall 12.

[0030] According to a preferred embodiment of the present invention, as Figure 1 shown, a sealing cover 13 is arranged on the top opening of the accommodation bottle 1. The sealing cover 13 is arranged in a shape adapted to the top opening for sealing the top opening. In this way, a sealed accommodation space is formed inside the accommodation bottle 1, thereby preventing the gel plugging agent inside the accommodation bottle 1 from leaking along the opening of the accommodation bottle 1 when the accommodation bottle 1 is inverted.

[0031] In one embodiment, as Figure 1 shown, the box body 21 includes a bottom plate 211 and side plates 212 arranged on the bottom plate 211 and extending upward. The side plates 212 enclose a hollow structure with a top opening and sealed all around. In this way, the bottom plate 211 and the side plates 212 can jointly form a cavity for placing the accommodation bottle 1. The box body 21 is arranged in any structure convenient for placing the accommodation bottle 1. In this embodiment, the box body 21 is configured as a square structure. However, the box body can also be arranged in structures such as circular and triangular.

[0032] Among them, a heater 22 is arranged on the bottom plate 211. In this setting, the air inside the box body 21 can be heated by the heater 22, so as to form a high-temperature environment inside the box body 21.

[0033] When the accommodation bottle 1 containing the gel plugging agent is placed inside the box body 21, the hot air can continuously and evenly heat the gel plugging agent in the accommodation bottle. When heated to an appropriate temperature, the accommodation bottle 1 is inverted inside the heating mechanism 2 by the rotating mechanism 3. At this time, the staff can detect the gelling performance of the gel plugging agent according to the gel visual code method, so as to study the gelling law and judge the gelling strength and gelling time.

[0034] According to a preferred embodiment of the present utility model, as Figure 1 shown, the heater 22 is arranged in a plate-like structure adapted to the bottom plate 211. At the same time, the heater 22 is laid along the plane formed by the bottom plate 211. In this way, when the heater 22 is used to heat the inside of the box body 21, the heat output by the heater 22 can continuously rise from the bottom of the box body 21, so that the air in the box body 21 is evenly heated.

[0035] In one embodiment, as Figure 1 shown, each side plate 212 and the bottom plate 211 are connected in a sealed manner. In this way, the box body 21 is formed into a sealed structure. When it is necessary to heat the containing bottle 1 located in the box body 21, a liquid can be added into the box body 21. In this embodiment, the liquid is set as water. Thus, the heating mechanism 2 can form a water bath heating mechanism. In this way, the containing bottle 1 in the box body 21 can be further heated evenly.

[0036] According to a preferred embodiment of the present utility model, as Figure 1 shown, a top cover 213 adapted to the opening is detachably arranged at the top opening of the box body 21. In this way, when the top cover 213 covers the top opening, the box body 21 can form a closed space, thereby avoiding heat dissipation.

[0037] In this setting mode, during use, first, the gel plugging agent to be detected is placed in the containing bottle 1, and the containing bottle 1 is sealed by the sealing cover 13. At the same time, the top cover 213 is removed from the box body 21, so that the heating mechanism 2 forms a top opening. Then, the containing bottle 1 is placed into the box body 21 along the opening, and the rotating mechanism 3 is connected to the containing bottle 1.

[0038] Secondly, a liquid is injected into the box body 21 so that the liquid submerges the containing bottle 1. At the same time, the cover plate 23 is covered on the opening of the box body 21, so that the box body 21 forms a closed space. Then, the heater 22 is started. Thus, a water bath heating mechanism is formed, and the containing bottle 1 located in the box body 21 is continuously heated, so that the gel plugging agent in the containing bottle 1 is continuously heated.

[0039] When the gel plugging agent in the containing bottle 1 reaches the appropriate temperature, the rotating mechanism 3 is rotated along the direction perpendicular to the axis of the containing bottle 1. At this time, the rotating mechanism 3 will drive the containing bottle 1 to rotate synchronously until the containing bottle 1 is in an inverted state.

[0040] At this time, the gel plugging agent located in the containing bottle 1 will continuously flow vertically downward along the side wall 12 of the containing bottle 1. During this process, the staff can record the gel visual code according to the gel visual code method, study the gel formation law, and judge the gel strength and gel formation time. Thus, the detection of the gel formation performance of the plugging agent is completed.

[0041] In one embodiment, as Figure 1 shown, the rotating mechanism 3 includes a rotating rod 32 that extends horizontally through the box body 21, and a fixing component 31 that is arranged on the rotating rod 32 and is used for clamping the containing bottle 1. In this setting mode, when a force is applied to the rotating rod 32 located outside the heating mechanism 2, the rotating rod 32 can drive the fixing component 31 to move synchronously, so that the containing bottle 1 on the fixing component 31 is inverted. At the same time, the connecting rod 32 is accommodated in a sealed manner at the position where the connecting rod 32 penetrates through the box body 21. In this way, it is possible to prevent the liquid in the box body 21 from leaking along the penetration.

[0042] In one embodiment, as Figure 1 shown, the fixing component 31 includes a first half-ring 311 with an inner diameter corresponding to that of the containing bottle 1, and a second half-ring 312 arranged corresponding to the first half-ring 311. In this way, when the first half-ring 311 and the second half-ring 312 are buckled with each other, a structure with an inner diameter adapted to the outer diameter of the containing bottle 1 can be formed, so as to circumferentially clamp the containing bottle 1 and enable the containing bottle 1 to be stably arranged in the fixing component 31.

[0043] According to a preferred embodiment of the present invention, as Figure 1 shown, the fixing component 31 further includes a fixing member (not shown in the figure) for detachably connecting the first half-ring 311 and the second half-ring 312 to each other. In this way, the fixing member 31 can clamp the containing bottle 1 in a selectable manner, so as to facilitate the installation and removal of the containing bottle 1.

[0044] According to a preferred embodiment of the present invention, as Figure 1 shown, a plurality of fixing components 31 are arranged in the heating mechanism 2, and a connecting member 33 is arranged on each fixing component 31, and the connecting member 33 is sleeved on the rotating rod 32. In this way, a plurality of containing bottles 1 can be placed in the box body 21, so as to jointly heat a plurality of containing bottles 1 filled with gel plugging agent inside. In this setting mode, the utilization rate of the internal space of the heating structure 2 can be improved.

[0045] According to a preferred embodiment of the present utility model, flexible gaskets (not shown in the figure) are arranged around the inner walls of the first half-ring 311 and the second half-ring 312. In this way, when the first half-ring 311 and the second half-ring 312 are used to clamp the accommodation bottle 1, the gasket can undergo elastic deformation, so as to further stably arrange the accommodation bottle 1 within the fixing assembly 31.

[0046] According to a preferred embodiment of the present utility model, a lighting mechanism 4 is arranged within the box body 21, and the lighting mechanism 4 can be opened or closed in a selectable manner. In this way, a light source can be provided for the inner cavity of the box body 21, so as to facilitate observing the state of the gel plugging agent within the accommodation bottle 1.

[0047] The operation of the device 100 for detecting the gelling performance of the gel plugging agent according to the present utility model is as follows.

[0048] First, remove the top cover 213 located on the heating mechanism 2, so that the heating mechanism 2 forms a structure with an open top. At the same time, arrange the rotating mechanism 3 within the heating mechanism 2, and arrange a plurality of fixing assemblies 31 on the rotating mechanism 3 within the heating mechanism 2, and make the rotating rod 32 extend outside the heating mechanism 2.

[0049] Secondly, place the gel plugging agent to be detected within the accommodation bottle 1, and seal the accommodation bottle 1 with the sealing cap 13. At the same time, place the accommodation bottle 1 into the heating mechanism 2 from the open top of the heating mechanism 2, and make the accommodation bottle 1 located on the fixing assembly 31. Thus, the accommodation bottle 1 is stably arranged on the heating mechanism 2.

[0050] Thirdly, add liquid along the open top of the heating mechanism 2 into the heating mechanism 2, and make the liquid submerge the accommodation bottle 1.

[0051] Then, start the heater 22, so that the heater 22 can uniformly heat the liquid located within the heating mechanism 2. At this time, the heat of the liquid can be transferred to the accommodation bottle 1, and heat the gel plugging agent located within the accommodation bottle 1. Thus, the device can form a water bath heating mechanism.

[0052] When the gel plugging agent within the accommodation bottle 1 reaches an appropriate temperature, rotate the rotating rod 32 along a direction perpendicular to the axis of the accommodation bottle 1. At this time, the rotating rod 32 will drive the fixing assembly 31 to move synchronously, so that the accommodation bottle 1 located on the fixing assembly 31 moves together until the accommodation bottle 1 presents an inverted state.

[0053] At this time, the gel plugging agent located in the accommodating bottle 1 will continuously flow vertically downward along the side wall 12 of the accommodating bottle 1. During this process, the gel visual code can be recorded according to the gel visual code method, the gel formation law can be studied, and the gel formation strength and gel formation time can be judged. Thus, the gel formation performance detection of the plugging agent is completed.

[0054] After the observation is completed, continue to rotate the rotating rod 32 until the accommodating bottle 1 returns to the heating state. At this time, the accommodating bottle 1 can be continuously heated. In this way, the accommodating bottle can be prevented from being exposed to the air during the detection process, so that the gel formation performance detection of the plugging agent can be completed without affecting the temperature field inside the accommodating bottle.
