[0001] The utility model relates to the technical field related to pipeline transportation, in particular to an oil field development and transportation pipeline with impurity removal effect. Background Art

[0002] Oilfield development pipelines play a vital role in the oil and gas industry. They are key facilities for transporting resources such as crude oil, natural gas and water from production sites such as oil wells, gas wells or water wells to processing plants, storage facilities or end users. These pipeline systems usually cover distances of hundreds to thousands of kilometers. However, during the oilfield development process, the inside of the pipeline is often affected by various forms of contamination and impurities, which may affect the efficiency of pipeline operation, the performance of processing equipment, and ultimately lead to an increase in production costs. Therefore, there is a particular need for an oilfield development pipeline with a decontamination effect.

[0003] However, most of the existing pipelines for oilfield development are not equipped with impurity removal functions. During the oilfield development process, various solid particles, sediments and impurities may exist in the pipelines. Without impurity removal functions, these impurities may accumulate and accumulate in the pipelines, causing pipeline blockage. Pipeline blockage will affect the normal transportation of fluids, reduce transportation efficiency, and even make the pipeline unable to operate normally. Utility Model Content

[0020] The filtering mechanism 2 includes an upper pipe 201, a mounting frame 202, bolts 203, an annular fixing block 204, a guide block 205, a threaded pipe 206, a connecting block 207, a filter cartridge 208, a filter element 209 and a lower pipe 210. The upper pipe 201 is installed inside the housing 1, the mounting frame 202 is installed at the upper end of the upper pipe 201, the bolts 203 are installed inside the mounting frame 202, the annular fixing block 204 is installed at the lower end of the upper pipe 201, the guide block 205 is installed on one side surface of the annular fixing block 204, the threaded pipe 206 is installed on one side surface of the guide block 205, the outer side of the threaded pipe 206 is threadedly connected to the connecting block 207, and the filter element 209 is installed on one side surface of the connecting block 207. The filter cartridge 208 is provided with a filter element 209 inside, and the lower end of the upper pipe 201 is provided with a lower pipe 210. By arranging the upper pipe 201, the mounting frame 202, the bolts 203, the annular fixing block 204, the guide block 205, the threaded pipe 206, the connecting block 207, the filter cartridge 208, the filter element 209 and the lower pipe 210, when installing, the upper pipe 201 is installed through the mounting frame 202 and the bolts 203, and the whole filtering mechanism 2 can be quickly installed. When the crude oil is transported, it is filtered through the filter cartridge 208 and the filter element 209 to efficiently filter the solid particles, sediments and impurities in the crude oil, so as to ensure that the quality of the transported crude oil meets the requirements.

[0021] Furthermore, the upper pipe 201 is connected to the housing 1 through the mounting frame 202 and the bolts 203. The upper pipe 201 and the mounting frame 202 fit tightly together. Through the arrangement of the upper pipe 201, the mounting frame 202 and the bolts 203, the bolts 203 are used for connection, which facilitates maintenance and overhaul. When maintenance or replacement is required, the upper pipe 201 can be disassembled by simply loosening the bolts 203, which is convenient and quick, reducing the time and cost of the maintenance process.

[0022] Furthermore, the filter cartridge 208 is connected to the threaded tube 206 through the connection block 207, and the filter cartridge 208 is tightly fitted with the inside of the threaded tube 206. Through the arrangement of the threaded tube 206, the connection block 207 and the filter cartridge 208, the threaded connection method makes the installation and replacement of the filter cartridge 208 and the pipeline system easier and more convenient. The installation can be completed by simply tightening the connection block 207, and when the filter cartridge 208 needs to be replaced, it can be replaced by simply unscrewing the connection block 207 without the need for complicated tools or equipment.

[0023] Further, the impurity removal mechanism 3 includes a mounting plate 301, a thread groove 302, a thread block 303 and an electromagnetic rod 304.

Through the arrangement of the mounting plate 301, the thread groove 302, the thread block 303 and the electromagnetic rod 304, after the electromagnetic rod 304 is opened, the iron filings inside the crude oil being transported are adsorbed, and the opening of the electromagnetic rod 304 enables it to have the ability to adsorb iron filings. When the crude oil passes through the upper half of the pipeline 201, the iron filings therein will be adsorbed on the electromagnetic rod 304, thereby effectively removing impurities in the crude oil. This helps to protect subsequent equipment from damage by iron filings and improves the operating efficiency and stability of the system.

[0024] Furthermore, the electromagnetic rod 304 is connected to the mounting plate 301 through the thread groove 302 and the thread block 303. The electromagnetic rod 304 is provided with multiple groups and is symmetrically arranged with the central axis of the mounting plate 301. Through the arrangement of the mounting plate 301, the thread groove 302, the thread block 303 and the electromagnetic rod 304, since the electromagnetic rod 304 is connected to the mounting plate 301 using the thread groove 302 and the thread block 303, the electromagnetic rod 304 can be relatively easily disassembled and replaced during maintenance. This structural design is simple, maintenance personnel can quickly operate, and reduce maintenance time and cost.

[0025] Working principle, when crude oil is transported, the crude oil enters through the oil inlet pipe 4, the electromagnetic rod 304 is turned on, the crude oil is prepared to be filtered, the iron filings mixed with the crude oil are adsorbed, and the crude oil passes through the guide block 205, the filter cartridge 208 and the filter element 209, and is filtered internally. After filtering, it is transported out through the oil outlet pipe 5. After the transportation is completed, the bolt 203 is removed from the mounting frame 202, and then the upper half of the pipeline 201 is removed, and then the connecting block 207 is rotated, and the filter cartridge 208 and the filter element 209 are pulled out from the inside of the guide block 205, and then replaced. The electromagnetic rod 304 is removed from the mounting plate 301 through the threaded groove 302 and the threaded block 303, and then the iron filings adsorbed by the electromagnetic rod 304 are cleaned, and then installed. After installation, the upper half of the pipeline 201 is installed. In this way, the use and maintenance of an oil field development and transportation pipeline with a de-impurity effect is completed.
