Description

Technical Field

[0001] The utility model relates to the technical field of petroleum exploration and measurement, in particular to a depth detector for shallow-sea petroleum underwater topography measurement. Background Art

[0002] In the field of offshore oil exploration, in order for the drilling platform to be installed normally and operate safely, it is necessary to use a depth sounder to detect the topography of the seabed. By detecting the topography of the seabed, the best installation location for the drilling platform can be found, and the drilling platform can be installed in shallow waters, which is conducive to offshore oil exploration activities.

[0003] A depth sounder, also known as a bathymeter, is typically installed on a ship or floating platform. It measures the depth of underwater terrain by emitting sound waves and receiving their reflections. The data obtained can be used to create underwater topographic maps and study seafloor landforms and ecosystems.

[0004] The depth sounder is mainly composed of the depth sounder host, GPS locator, transducer, and transducer connecting rod. The transducer connecting rod should always be kept perpendicular to the horizontal plane. After connecting to the GPS locator, the water depth points measured by the depth sounder all correspond to positioning coordinates, and the measured water depth points should be the phase center of the GPS locator.

[0005] At present, traditional depth detectors used for shallow-water petroleum underwater topography measurements can always remain perpendicular to the horizontal plane and can usually work normally in water bodies with small surface fluctuations such as inland waterways, lakes, and reservoirs. However, in shallow waters, due to the shallow depth of the shallow sea, the water body is blocked by land, forming backflows and harbors, and reflection, diffraction, and interference effects occur when the waves propagate, making the wave fluctuations more complex and violent. Moreover, when the sea depth becomes shallower, the waves will feel the obstruction of the seabed, making the wave crests and troughs steeper, the wave speed slows down, and the wavelength shortens, forming steeper and more dangerous wave crests.

[0006] In shallow waters, where wave heights typically range from tens of centimeters to several meters, traditional depth detectors used for shallow-water petroleum underwater topography measurements will experience dramatic ups and downs as ships or floating platforms are affected by the waves. This can cause the depth detectors to be unable to maintain a stable altitude. The large height difference between the sound waves emitted by the depth detectors and the location where their reflections are received can greatly affect the accuracy of underwater topography depth data measured by the depth detectors.

[0007] Therefore, it is necessary to design a depth detector for shallow-water petroleum underwater topography measurement. Utility Model Content

[0008] To this end, the utility model provides a depth detector for shallow-water petroleum underwater topography measurement to solve the problem that in shallow sea areas, ships or floating platforms are violently up and down due to the influence of waves, resulting in the depth detector for topography measurement being unable to maintain a stable altitude.
