Description

Technical Field

[0001] This utility model relates to the field of corrosion-resistant plate placement and removal technology, specifically to a convenient device for placing and removing corrosion-resistant plates in oilfields with high sulfur content. Background Technology

[0002] Oil pipelines are primarily used to transport crude oil, associated gas, and produced water (collectively referred to as oil-gas-water) extracted from oil wells. These substances often contain corrosive components such as hydrogen sulfide and carbon dioxide. During extraction in high-sulfur oil fields, these components can corrode the pipelines, affecting normal oilfield production and potentially posing safety and environmental hazards. To understand the corrosion rate of the pipelines, detection plates are installed inside. After a certain exposure period, these plates are removed, cleaned, and weighed. The average corrosion rate is then measured based on the change in sample mass. The existing technology has the following problems:

[0003] Existing methods for applying corrosion-resistant strips to downhole pipelines typically involve suspension. Downhole pipelines cannot be directly connected to the corrosion-resistant strip device, making it inconvenient to place more corrosion-resistant strips in different locations. This results in high difficulty and low accuracy in monitoring corrosion of downhole pipelines in oil and gas wells. Furthermore, the complex handling of corrosion-resistant strips reduces the ease of use of the device. Summary of the Invention

[0007] A further improvement of this utility model is that the hanging plate connector includes a mounting post, an annular protrusion, several insert rods, a positioning block, and a threaded head. The mounting post is cone-shaped, the inner wall of the annular protrusion is fixedly connected to the outer wall of the mounting post, the bottoms of several insert rods are respectively annularly arrayed and fixedly connected to the upper surface of the annular protrusion, the bottom of the positioning block is fixedly connected to the top of the mounting post, and the bottom of the threaded head is fixedly connected to the top of the positioning block.

[0008] A further improvement of this utility model is that: a through mounting hole is provided on one side of the top of the corrosion plate, and a number of insertion holes adapted to the insertion rod are provided in a ring array on the outer side of the top of the long screw near the mounting hole.

[0009] A further improvement of this utility model is that: the interior of the mounting hole is sleeved with the outer wall of the mounting column, the interior of the insertion hole is inserted with the outer wall of the insertion rod, and the lower surface of the mounting hole overlaps with the outer wall of the mounting column.

[0010] A further improvement of the present invention is that: a threaded hole 2 is provided at the bottom of the mounting column, and a positioning groove 2 is provided on the outer wall of the bottom of the mounting column near the threaded hole 2; the inner wall of the threaded hole 2 is threadedly connected to the outer wall of the threaded head, and the inner wall of the positioning groove 2 engages with the outer wall of the positioning block.

[0015] 1. This utility model provides a convenient device for placing and removing corrosion-resistant hanging plates in high-sulfur oilfields. It utilizes the cooperation between a connecting block, hanging plate connectors, and corrosion-resistant hanging plates. The corrosion-resistant hanging plates are parallelly fitted onto the hanging plate connectors through mounting holes and positioned by engaging with the insert rod through insertion holes. Adjacent hanging plate connectors are vertically connected by threads, allowing for convenient placement of the corrosion-resistant hanging plates in different locations. The uppermost hanging plate connector is then threaded onto the connecting block. This solves the problem that existing methods for applying corrosion-resistant hanging plates to downhole pipelines typically involve suspension, making it difficult to directly connect the downhole pipeline to the device and inconvenient to place more corrosion-resistant hanging plates in different locations. This results in high difficulty and low accuracy in monitoring corrosion of downhole pipelines in oil and gas wells. The device achieves the beneficial effect of conveniently installing corrosion-resistant hanging plates in different locations, improving the accuracy of testing.

[0016] This utility model provides a convenient device for retrieving and placing corrosion-resistant hanging plates in high-sulfur oilfields. It utilizes a long screw, mounting components, and an operating rod in conjunction with each other. The mounting components fix the device around the perimeter of the downhole pipeline. When retrieving or placing the corrosion-resistant hanging plates, rotating the operating rod causes the hanging plates, mounted on the hanging plate connector, to move up and down along the well pipe, facilitating the retrieval of the plates. This solves the problem of complex handling of corrosion-resistant hanging plates, which reduces the ease of use of the device, and achieves the beneficial effect of improving the ease of use of the device.

[0030] The working principle of this convenient high-sulfur content oilfield corrosion-resistant hanging plate removal and placement device will be explained in detail below.

[0031] like Figure 1-5As shown, when mining downhole pipelines in high-sulfur oilfields, this device is used to install detection clips at different locations inside the pipeline. After a certain exposure period, the clips are removed, cleaned, and weighed. The average corrosion rate is measured based on the change in sample mass. First, the corrosion clip 6 is inserted parallel from top to bottom along the tip of the mounting post 51 through the mounting hole 601. The insertion holes 602 around the mounting hole 601 are aligned with the insertion rod 53, so that the mounting hole 601 is tightly fitted to the outer surface of the mounting post 51 through friction. Then, the other corrosion clips 6 are installed sequentially on other clip connectors 5 using the same steps. The installation angle of the corrosion clips 6 can be adjusted during this process. Finally, the two clip connectors 5 are fixed by vertically screwing the threaded heads 55 together. In the threaded hole 510 at the bottom of the adjacent mounting post 51, the positioning block 54 is tightly engaged in the positioning slot 511 for positioning, thus placing multiple corrosion hangers 6 in different positions. Then, the threaded head 55 on the uppermost mounting post 51 is screwed into the threaded hole 401, and the positioning block 54 is tightly engaged in the positioning slot 402 for positioning. Then, the corrosion hanger 6, together with the long screw 1, is placed into the downhole pipeline. The L-shaped frames 23 on both sides are placed outside the pipeline, and the fixing bolts 25 are screwed into the mounting frame outside the pipeline from top to bottom through the fixing holes 240. After a certain exposure period, by rotating the operating rod 3, the long screw 1 is rotated along the threaded sleeve 21, so that the corrosion hanger 6 inside the downhole pipeline can be moved upward and removed.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
