Embodiment Construction
[0025] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the present invention will now be described with reference to the accompanying drawings.
[0026] Such as figure 1 and figure 2 As shown, the present invention proposes a device for the relative position of the sub-array spacing of the stable seismic source array in water, and the device for the relative position of the sub-array spacing of the stable seismic source array in water includes:
[0027] The traction ring 1 is installed on the tail of the sub-array floating body of the stable seismic source array in water, and the traction ring 1 can be connected with the tail of the sub-array floating body by a rope;
[0028] The bottom frame 4 is annular and mainly plays an integral supporting role. The bottom frame is separated from the traction ring 1 and is at a certain distance from the traction ring 1;
[0029] The bottom plate 3 is circular and filled...

The invention provides a device and a method for stabilizing relative positions of subarray gaps of seismic focus arrays in water. The device for stabilizing relative positions of the subarray gaps of the seismic focus arrays in water comprises traction rings mounted at the tails of subarray floating bodies of the seismic focus arrays, baseplate skeletons taking the shape of rings and spaced from the traction rings, baseplates being circular and disposed in the baseplate skeletons, and connecting columns connected between the baseplate skeletons and the traction rings. The method for stabilizing relative positions of the subarray gaps of the seismic focus arrays in water adopts the device for stabilizing relative positions of the subarray gaps of the seismic focus arrays in water, and comprises the step of connecting the traction rings to the tails of the subarray floating bodies of the seismic focus arrays through ropes. The device and method can increase the navigation resistance and reduce the influence of water flows on the floating bodies and subarrays, so that the offset of the tails of the floating bodies is within a certain control range and the subarray gaps can be controlled.
Description
technical field [0001] The invention relates to the field of geophysical exploration, in particular to a device and method for stabilizing the relative position of sub-array spacing of sub-arrays in offshore oil exploration, that is, a device and method for the relative position of sub-array spacing of stable sub-arrays of sub-arrays in water. Background technique [0002] During the oil exploration operation in the beach-sea transition zone, the source ship travels at a certain speed, and the stern of the ship drags the source array. The source array is composed of multiple independent sub-arrays, each sub-array is suspended on the corresponding floating body, the floating body and the sub-array are connected by a depth-fixing rope, and the sub-array is suspended in the water at a certain depth relying on the buoyancy of the buoyancy body and the depth-fixing rope. Each sub-array is released to a distance of 15-20 meters from the stern of the ship through the retractable me...
