[0002] Oil and natural gas transportation is an important part of oil and gas field exploitation, among which pipeline transportation is the most common way; natural gas extracted from oil fields usually contains complex media such as water, hydrogen sulfide, carbon dioxide, etc., and needs to be transported to the combined station for processing through gathering and transportation pipelines. Due to the high pressure and low ambient temperature during pipeline transportation, natural gas hydrates are easily generated during oil and gas transportation and block the pipelines; at present, the method used to prevent hydrates from clogging pipelines is to add hydration The most commonly used hydrate formation inhibitor is methanol. According to incomplete s

Example Embodiment
[0036] Below in conjunction with the accompanying drawings and specific embodiments, the content of the present invention is described in further detail:
[0037] The helical flow generator in the present invention is as figure 1, consisting of a double-headed diversion strip, which is set along the inner wall of the pipeline; for the diversion strip, the width a is 0.01~0.1D, and the height h is 0.15~0.25D. Considering that the circumferential velocity of hydrate particles needs to be greater than the critical velocity, But it does not affect the axial flow, so the angle with the pipe wall is 15°~45°, the material is 16Mn, and the welding connection with the inner wall of the pipe is adopted. The schematic diagram of the installation section is as follows figure 2 shown.
[0038] The hydrate decomposition process of the present invention is as follows image 3 As shown, the detailed scheme is as follows, the adopted device includes: the spiral pipeline 3 is connected with...

The invention belongs to the field of petroleum engineering and relates to the technology of natural gas storage and transport, in particular to a whole-course swing spiral flow conveying pipeline and natural gas hydrate decomposing process device. A natural gas hydrate pipeline conveying device is composed of flow guide strips at two ends, the two flow guide strips are symmetrically arranged in a pipe wall, are fixed around the inner wall of a pipeline in the same direction in the whole course and form a spiral shape, and a spiral pipeline is formed. By means of the pipeline spiral gas hydrate conveying method, addition of inhibitors, polymerization inhibitors and other chemicals is omitted, and conveying safety and economical efficiency of natural gas are improved. By the adoption of a three-stage hydrate decomposing tower, carbon dioxide and hydrogen sulfide are effectively separated out, traditional natural gas desulfuration and decarbonization equipment is omitted, and water in the whole process is recycled through a water storage tank. Besides, a solar heat collector is used for heating the water, energy consumption is low, and the requirements for economic efficiency, environment protection, high efficiency, recyclability and the like are met.
