The method comprises the following steps: Step A: According to the inner diameter of the deepwater oil and gas pipeline 100, the distance between the rear roller 101 and the rear transmission screw 21 and the distance between the front roller 102 and the front transmission screw 41 are adjusted respectively, including the following specific steps: The steps for adjusting the distance between the rear roller 101 and the rear drive screw 21 are as follows: starting the spacing adjustment motor 20, the output shaft of the spacing adjustment motor 20 drives the rear drive screw 21 to rotate, and then drives the threaded sleeve 22 to move forward or backward along the rear drive screw 21, thereby pushing multiple groups of the rear drive connecting rods 23 to expand outward at the same time and approach the inner wall of the deep-water oil and gas pipeline 100, or pulling multiple groups of the rear drive connecting rods 23 to close inward at the same time and away from the inner wall of the deep-water oil and gas pipeline 100, thereby realizing the adjustment of the distance between the rear roller 101 and the rear drive screw 21 to adapt to deep-water oil and gas pipelines 100 with different inner diameters.

[0051] Steps for adjusting the distance between the front roller 102 and the front drive screw 41: the rear drive screw 21 drives the connecting rod 443 to rotate through the fixed seat 3 and the rotating seat 441, and the connecting rod 443 drives the front drive screw 41 to rotate. When the front drive screw 41 rotates, it drives the front seat 5 to move forward or backward relative to the rotating sleeve 42, thereby pushing multiple groups of the front drive connecting rods 43 to expand outward at the same time and approach the inner wall of the deep-water oil and gas pipeline 100, or pulling multiple groups of the front drive connecting rods 43 to close inward at the same time and away from the inner wall of the deep-water oil and gas pipeline 100, thereby realizing the adjustment of the distance between the front roller 102 and the front drive screw 41 to adapt to deep-water oil and gas pipelines 100 with different inner diameters.

[0052] Step B: Start the running drive motor 60, and the running drive motor 60 drives the transmission rod 63 to rotate through the transmission shaft 61, the transmission bevel gear 621 and the matching bevel gear 622 in sequence. When the transmission rod 63 rotates, it can drive the two rollers to rotate, thereby driving the pipeline runner to move inside the deepwater oil and gas pipeline 100.

[0053] When the pipeline runner moves inside the deepwater oil and gas pipeline 100, the scanning probe 11 of the data acquisition head 1 scans the hydrate particles on the inner wall of the deepwater oil and gas pipeline 100, and the ultrasonic probe 12 performs ultrasonic detection on the inner wall of the deepwater oil and gas pipeline 100 to collect data on the thickness and shape of the hydrates in each section of the deepwater oil and gas pipeline 100.

[0054] Step C: The data acquisition head 1 acquires the effective volume of hydrate particle growth on the inner wall of the deepwater oil and gas pipeline 100 and sends the acquired data to the controller, which sends the data of hydrate thickness and shape in each section of the pipeline to the storage unit for temporary storage.

[0055] When the temporarily stored data is transmitted to the calculator through the external interface, the calculator calculates the hydrate volume of the inner wall of each section of the pipeline according to the thickness and shape of the hydrate in each section of the pipeline, and adds up all the hydrate volumes measured by the pipeline runner on the movement path in the pipeline, so as to calculate the total volume of hydrated particles on the inner wall of the deepwater oil and gas pipeline 100.
