Description

Technical Field

[0001] The utility model relates to the technical field of petroleum transportation, in particular to a multi-cavity pipeline for oil well transportation. Background Art

[0002] At present, in the process of oil exploitation and utilization, transporting the crude oil produced in the oil field is a very important step. However, the crude oil produced in the oil field generally has the characteristics of high wax content, high freezing point and high viscosity. Therefore, in order to prevent oil, gas and water from condensing during transportation, it is urgently necessary to use an oil pipeline that can reduce the viscosity of oil to safely transport the oil from the wellhead of the oil well to the metering station or transfer station.

[0003] The utility model of patent number CN216407934U discloses an oil pipeline with a protective structure for oil exploration, which can play an effective protective effect in the long-term use of the oil pipeline, avoiding damage to the pipeline caused by bumps during use, and reusing the clamping block, bolts and docking block, which can be easily installed, effectively improving the use efficiency and work efficiency of the oil pipeline, and also improving the service life of the oil pipeline, meeting people's use needs, and bringing convenience to people's use. However, in the actual use process, it is impossible to heat the oil in the pipeline during transportation, which causes the viscosity of the crude oil to increase, and it will adhere to the inner wall of the pipeline, resulting in a decrease in the flow of crude oil in the pipeline, which in turn leads to a decrease in transportation efficiency and the need for regular maintenance or replacement of the pipeline. To this end, we propose a multi-chamber pipeline for oil well transportation. Utility Model Content

[0006] By adopting the above technical solution, firstly, the pipeline wall is heated by the electric heating structure which is easy to disassemble and install when the oil is transported in the oil pipeline, thereby reducing the occurrence of the situation in which the oil encounters the low-temperature section during the movement and causes solidification and adhesion to the pipeline wall, thereby improving the transportation efficiency in the process of transporting oil, ensuring the circulation volume of crude oil transportation, and reducing the loss in the process of oil transportation.

[0007] Specifically, a first locking socket is formed between two through-connecting slots on the tube wall at one end of the multi-lumen tube, and a transfer connection electrical plug-in is detachably installed inside the first locking socket.

[0009] Specifically, a second connecting hole having the same position and matching size as the first locking hole is formed on the tube wall of one end of the multi-lumen tube away from the first locking hole.

[0010] By adopting the above technical solution, the transfer connection point plug-in is connected through the second connecting jack and the first locking jack, thereby connecting the circuits between the multi-lumen tubes.

[0011] Specifically, an oil delivery hole is opened through the center of the multi-lumen tube.
