Abstract
Description
Technical Field
[0001] This utility model relates to the field of crude oil testing technology, specifically an intelligent online crude oil water content tester. Background Technology
[0002] In clastic rock reservoirs, crude oil and formation water coexist as two phases. During extraction, the formation pressure decreases, and the water phase is displaced along with the crude oil into the wellbore to form associated water. In order to facilitate subsequent extraction, processing and trading, it is necessary to test the crude oil containing water to obtain the water content of the crude oil.
[0003] Existing intelligent online crude oil water content testers are prone to errors when testing crude oil water content because oil and water in crude oil tend to separate into layers due to their different densities when left to stand. This results in differences in the water content of crude oil at different locations, which in turn leads to errors in the testing of crude oil water content and affects subsequent crude oil processing.
[0004] Therefore, this utility model provides an intelligent online crude oil water content tester to solve the above problems. Utility Model Content

[0021] Addressing the issue that existing intelligent online crude oil water content analyzers are prone to inaccurate results due to oil-water stratification when testing crude oil water content, such as... Figure 1 and 2 As shown in the figure, this disclosure provides an intelligent online crude oil water content tester, including a base 1, a barrel 3, a first drive body 2, a test body, and an enhancement body. A second drive body 4 is installed on one side of the base 1, and the barrel 3 is slidably installed above the drive body. The second drive body 4 is installed on the base 1. The enhancement body includes a stirring body 5 and a cleaning body 7. The stirring body 5 is installed on the side of the second drive body 4. The stirring body 5 contains a retractable test body, and the stirring body 5 contains a cleaning body 7.
[0022] It should be noted that the test body can use any existing structure or device capable of online testing of crude oil water content, such as the test probe 6 used in existing capacitive water content analyzers, radio frequency water content analyzers, microwave water content analyzers, and infrared spectral water content analyzers. In this embodiment, the test probe 6 used in a capacitive water content analyzer is employed.
[0023] like Figure 1 As shown, one end of the test probe 6 is placed in the crude oil for testing, and the other end is connected to an external testing instrument.
[0024] During the crude oil water content testing process, crude oil is transported into barrel 3. Then, the first drive unit 2 is activated, moving barrel 3 upwards towards the test specimen, ensuring the test specimen is positioned within barrel 3 for water content testing. Next, the second drive unit 4 activates the stirring unit 5 to agitate the specimen, forcibly mixing the oil and water evenly. This prevents measurement deviations and ensures uniform and accurate results. Furthermore, during the agitation process, after stirring by the stirring unit 5, the first drive unit 2 continues to move barrel 3 upwards. This causes barrel 3 to compress and extend the stirring unit 5, simultaneously moving the cleaning unit 7 longitudinally. The cleaning unit 7 cleans the surface of the test specimen, preventing impurities from adhering and thus ensuring accurate results for the crude oil water content test.
[0025] like Figure 1 As shown, the first driving body 2 includes a lead screw 21, a first driving motor 22, and a support platform 23. The lead screw 21 is rotatably mounted on one side of the base 1, the first driving motor 22 is coaxially fixedly mounted on the top of the lead screw 21, and an auxiliary rod is fixedly mounted on the other side of the lead screw 21. The support platform 23 is slidably mounted on the surfaces of the lead screw 21 and the auxiliary rod.
[0026] During the process of starting the first drive unit 2 after placing crude oil in the barrel 3, the first drive motor 22 is started first to drive the lead screw 21 to rotate. The rotation of the lead screw 21 causes the bearing platform 23 to slide longitudinally on the surface of the lead screw 21 and the auxiliary rod, thereby causing the barrel 3 to move upward and approach the stirring body 5, and causing the stirring body 5 and the test body to extend into the barrel 3. This allows the stirring body 5 to force the oil and water in the barrel 3 to mix after starting, and allows the test body to test the water content of the oil and water in the barrel 3 after forced mixing.
[0027] The auxiliary rod core is used to maintain the upward stability of the support platform 23 and the barrel 3.
[0028] like Figure 1 and 2As shown, the stirring body 5 includes an outer shaft 51, an inner shaft 52, and a rod 53. The outer shaft 51 is rotatably installed inside the top wall of the base 1. The inner shaft 52 is slidably installed inside the outer shaft 51 through a sliding body 54. The rod 53 is fixedly installed at the bottom of the inner shaft 52. Blades 55 are fixedly installed on the outer surface of the outer shaft 51. A cleaning body 7 is fixedly installed at the top of the inner shaft 52.
[0029] After the first driving body 2 moves the support platform 23 and the barrel 3 upward, the second driving body 4 drives the outer shaft 51 to rotate, so that the rotating shaft drives the inner shaft 52 to rotate synchronously through the sliding body 54. This causes the outer shaft 51 and the inner shaft 52 to rotate synchronously and stir through the blades 55, thereby forcibly mixing the oil and water in the barrel 3. This avoids inaccurate testing caused by oil-water separation and helps improve the accuracy of crude oil water content testing.
[0030] like Figure 1 As shown, the second driving body 4 includes a second driving motor 41, a driving gear 42, and a gear ring 43. The second driving motor 41 is fixedly installed on the top of the base 1. The driving gear 42 is fixedly installed on the second driving motor 41 on the same axis. The gear ring 43 that meshes with the driving gear 42 is fixedly installed on the outer surface of the outer shaft 51.
[0031] During the process of starting the stirring body 5 to rotate, the second drive motor 41 is started first, which drives the drive gear 42 to rotate. The rotation of the drive gear 42 drives the meshing gear ring 43 to rotate, which in turn drives the outer shaft 51 fixedly connected to it to rotate. The rotation of the outer shaft 51 drives the inner shaft 52 to rotate synchronously, so that the inner shaft 52 and the outer shaft 51 rotate synchronously to stir and force mix the crude oil.
[0032] like Figure 2 As shown, the sliding body 54 includes a protrusion 541 and a groove 542. The groove 542 is provided axially inside the outer shaft 51, and the protrusion 541, which slides in the groove 542, is fixedly provided on the outside of the inner shaft 52.
[0033] During the rotation of the outer shaft 51, the longitudinally sliding protrusion located in the groove 542 enables the outer shaft 51 and the inner shaft 52 to rotate synchronously. This ensures that while the protrusion slides longitudinally in the groove 542, allowing the inner shaft 52 to extend and retract within the outer shaft 51, the inner shaft 52 and the outer shaft 51 rotate synchronously to force the oil and water to mix and stir.
[0034] After the first driving body 2 moves the barrel 3 upward and activates the second driving body 4 to drive the stirring body 5 to stir, the first driving body 2 again moves the barrel 3 upward and squeezes the rod 53. This causes the rod 53 to slide longitudinally along the protrusion on the outer surface of the inner shaft 52 within the groove 542. Consequently, the rod 53 and the inner shaft 52 slide longitudinally into the outer shaft 51, exposing the test subject for testing. During the retraction process of the rod 53 and the inner shaft 52, the cleaning body 7 wipes the surface of the test subject, ensuring its cleanliness and preventing impurities from adhering to the surface and affecting testing accuracy.
[0035] like Figure 2 As shown, the cleaning body 7 has a through hole 71 in the middle to accommodate the test body. During the longitudinal movement of the cleaning body 7, the test body passes through the through hole 71, thereby cleaning the test body and keeping the surface of the test body clean.
[0036] It should be noted that the cleaning body 7 can be made of any flexible material that will not damage the test body in the prior art, such as sponge, non-woven fabric, fiber cloth, or rubber.
[0037] like Figure 1 As shown, blades 55 are fixedly mounted on the inner surface of the inner shaft 52. During the rotation of the inner shaft 52, the blades 55 on the inner surface of the inner shaft 52 can rotate synchronously, thereby further forcing the oil and water near the test body to mix, thus ensuring the accuracy of the test body in measuring the water content of crude oil.
[0038] The testing process for the water content of crude oil in this embodiment is as follows: Crude oil is delivered into barrel 3. Then, the first drive unit 2 is activated, i.e., the first drive motor 22 drives the lead screw 21 to rotate. The rotation of the lead screw 21 causes the support platform 23 to slide longitudinally on the surface of the lead screw 21 and the auxiliary rod, thereby causing barrel 3 to move upwards and approach the agitator 5 for the first time, so that the outer shaft 51 and the inner shaft 52 are located inside barrel 3 and the rod 53 does not contact the bottom of barrel 3. Then, the second drive unit 4 is activated to drive the agitator 5 to rotate and force the oil and water to mix. That is, the second drive motor 41 is activated, which drives the drive gear 42 to rotate. The rotation of the drive gear 42 drives the meshing gear ring 43 to rotate, thereby driving the outer shaft 51, which is fixedly connected to it, to rotate. The rotation of the outer shaft 51 drives the inner shaft 52 to rotate synchronously, so that the inner shaft 52 and the outer shaft 51 rotate synchronously to agitate and force mix the crude oil.
[0039] After the second drive body 4 drives the stirring body 5 to rotate and forcibly mix the oil and water, the second drive body 4 and the stirring body 5 are stopped, and the first drive body 2 is restarted, causing the support platform 23 and the barrel 3 to move upward again. The support platform 23 and the barrel 3 move upward again, so that the bottom of the barrel 3 contacts the rod 53 and drives the rod 53 to move upward. This causes the protrusion on the outer surface of the inner shaft 52 to slide longitudinally in the groove 542, so that the rod 53 drives the inner shaft 52 to slide longitudinally and retract within the outer shaft 51, thus exposing the test object for testing. During the process of the rod 53 driving the inner shaft 52 to move longitudinally and retract, the cleaning body 7 can wipe the surface of the test object to ensure the cleanliness of the test object surface and avoid impurities adhering to the surface of the test object, which would affect the test accuracy.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
