Description

Technical Field

[0002] The acidizing fluid is a mixture of hydrochloric acid, hydrofluoric acid, acetic acid, corrosion inhibitors, drainage aids, etc. in the required proportions and is used for acidizing or fracturing construction of oil and water wells in various domestic oil fields.

[0003] By chemically reacting the acidizing fluid with rocks, blockages, organic matter, etc., the blockages can be dissolved, thereby achieving the effect of clearing the bottom layer and establishing a seepage channel. The effect of the acidizing fluid is mainly through its own chemical properties. Therefore, before it is actually used, it is necessary to test whether various indicators are qualified to achieve the effect of stable dissolution of the blockage. However, when faced with multiple tests on the acidizing fluid, existing devices generally extract samples separately and then test them. It is impossible to take samples and test them simultaneously for multiple times, and it is impossible to test the acidizing fluid under different flow rate states, which affects the efficiency of the device in testing the acidizing fluid.

[0004] Therefore, we provide an oilfield acidizing fluid detection device. Utility Model Content

[0025] Example 1

The inner wall of the shunt pipe 5 at one end away from the collecting barrel 4 is fixedly connected to a support cone 6, and several flow ports 7 are opened on the outside of the support cone 6. A closed cone 8 is inserted on one side of the support cone 6, and several guide tubes 12 are arranged below the closed cone 8. The several guide tubes 12 are fixedly connected to a collecting barrel 13 at the same time, and a rotating shell is arranged on the outside of the collecting barrel 13. 15, the rotating shell 15 is threadedly connected with the shunt pipe 5, and the rotating shell 15 is located outside the shunt pipe 5. When the device is in operation, the rotating shells 15 on the multiple shunt pipes 5 outside are rotated separately or simultaneously, so that the closed cone 8 located inside the shunt pipe 5 moves downward under the drive of the rotating shell 15, so that a gap is generated between the closed cone 8 and the support cone 6, so that the acidified liquid inside the sample storage barrel 1 flows to the support cone 6 under the guidance and support of the shunt pipe 5, and the acidified liquid inside the sample storage barrel 1 flows to the support cone 6 through the multiple flow ports opened on the support cone 6. 7 can make the internal acidified liquid flow into the multiple guide tubes 12 below, and then flow into the detection component under the guidance of the manifold 13. After the required detection sample is sufficient, the closing cone 8 is moved upward by rotating the rotating shell 15 in the opposite direction so that it is tightly plugged with the supporting cone 6 to achieve the effect of sealing the flow port 7. By rotating the multiple rotating shells 15 simultaneously or separately under the support of the diversion pipe 5, and then placing different detection parts 141 respectively under the manifold 13, the device can detect multiple items at the same time, thereby improving the detection efficiency of the device for the acidified liquid. At the same time, by rotating the multiple rotating shells 15 on the outside to different degrees to control the different flow rates of the internal acidified liquid, the effects of the acidified liquid with different flow rates can be observed at the same time, and the peak value of the use of the acidified liquid can be found to improve its use effect. Moreover, by disassembling the rotating shell 15, the device can be easily cleaned to ensure the accuracy of the results when the next detection is used, thereby improving the detection efficiency of the device and the accuracy of the detection results.

A circulation ring 10 is provided at the upper end of the closed disk 9. A guide port 11 is provided at the lower half of the circulation ring 10. There are several guide ports 11, which are connected to a guide pipe 12. After the acidified liquid in the device flows to the surface of the closed cone 8 under the support of the supporting cone 6, the acidified liquid can accurately flow to the inside of the circulation ring 10 by providing a guiding effect by setting the closed cone 8 as a conical structure. Then, under the circulation effect of the multiple guide ports 11 in the circulation ring 10, the acidified liquid can accurately flow to the lower device under the guidance and convergence of the guide pipe 12. The flow velocity of the acidified liquid can be controlled by the diversion and convergence effect of the supporting cone 6, the guide port 11 and the guide pipe 12 when the acidified liquid flows, so as to prevent it from flowing out too quickly, thereby ensuring the accuracy of the acidified liquid extraction.

The closed connection column 16 is located inside the support cone 6. When the rotating shell 15 rotates and moves outside the shunt pipe 5, the closed connection column 16 will be rotated and connected inside the shunt pipe 5 at the same time. The closed connection column 16 and the rotating shell 15 can simultaneously connect and rotate the shunt pipe 5 from both the inside and the outside, thereby ensuring the stability of the sealing effect of the shunt pipe 5, thereby improving the safety of the acidified liquid circulation inside the device.

At least two arc-shaped limiting plates 18 are fixedly arranged on the upper end of the support seat 17, and the sample storage barrel 1 is located between the two arc-shaped limiting plates 18. The support and protection effect of the support seat 17 on the overall device, and the limiting effect of the two arc-shaped limiting plates 18 on the sample storage barrel 1, ensure the stability of the sample storage barrel 1 when filling with acidifying liquid, and under the display effect of the capacity observation window 2 and the capacity indicator gauge 3, the staff can intuitively see the flow of the acidifying liquid inside the device, which can improve the accuracy of its extraction, thereby ensuring the accuracy of the test results.

[0032] Working principle: by rotating the rotating shell 15 on the outer multiple shunt pipes 5 separately or simultaneously, the closed cone 8 located inside the shunt pipe 5 moves downward under the drive of the rotating shell 15, so that a gap is generated between the closed cone 8 and the support cone 6, so that the acidified liquid inside the sample storage barrel 1 flows to the support cone 6 under the guidance and support of the shunt pipe 5, and the acidified liquid inside can flow to the multiple guide pipes 12 below through the multiple flow ports 7 opened on the support cone 6, and then flows to the inside of the detection component under the guidance of the confluence tube 13. When the required test sample is sufficient, it is passed through The rotating shell 15 is rotated in the opposite direction to move the closing cone 8 upward so that it can be tightly plugged into the supporting cone 6, thereby achieving the effect of sealing the flow port 7. By rotating multiple rotating shells 15 simultaneously or separately under the support of the diversion pipe 5, and then placing different detection parts 141 respectively under the confluence tube 13, the device can detect multiple items at the same time, thereby improving the detection efficiency of the device for the acidified liquid, and by disassembling the rotating shell 15, the device can be easily cleaned to ensure the accuracy of the results when it is used for the next detection, thereby improving the detection efficiency of the device and the accuracy of the detection results.
