Description

Technical Field

[0001] The utility model relates to the technical field of oil and water well unblocking, in particular to an oil and water well acid unblocking auxiliary device. Background Art

[0002] An oil well is a hole drilled through a drilling process. Generally, after reaching the oil layer, casing is lowered into the oil layer, and oil well cement is injected into the annular space between the casing and the wellbore to maintain the wellbore and seal the oil, gas, and water layers. Perforating guns are then used to perforate the oil layer according to the requirements of oilfield development, forming a channel. Pipelines are then lowered and, using appropriate induction methods, the oil is raised from the bottom of the well to the wellhead. Over time, oil transportation pipelines accumulate a layer of scale within the pipe walls, which can easily become clogged and require acidification to remove the blockage.

[0034] The working principle of the oil and water well acidizing and plugging auxiliary device provided by the utility model is as follows:

[0035] When using the device, the branch pipe 1 in the device can be connected to the injection pipe in the external blocking agent injection device, and then multiple driving rods 41 can be taken out and assembled as needed, and then the assembled driving rods 41 can be connected to the support plate 4;

[0036] After the drive rod 41 is installed, the device can be inserted into the pipe to be treated, and the external injection device can be controlled to work. At this time, the injected blocking agent can flow into the adapter 21 through the branch pipe 1, and then flow into the liquid guide ring 211, nozzle 212 and nozzle 213 connected to it through the adapter 21;

[0037] The blocking agent sprayed from the nozzle 212 can be evenly diffused toward the inside of the pipe, and the blocking agent sprayed from the nozzle 213 can be sprayed toward the corresponding water receiving frame 231 on the outside. The impact force generated by the spraying can drive the rotating frame 22 to rotate on the outer wall of the branch pipe 1. At this time, the rotating frame 22 can scrape and clean the inner wall of the pipe through the external cleaning brush 221;

[0038] During this process, the staff can push the external driving rod 41 to make the device move stably inside the pipeline, thereby achieving uniform cleaning of the inside of the pipeline. In this process, multiple annular scraping strips 51 located on the support frame 3 can be abutted against the inner wall of the pipeline to perform secondary scraping and cleaning of the inner wall of the pipeline, thereby improving the unblocking effect of the pipeline.
