Embodiment 1）

[0043] See Figure 1 to Figure 3 The source cable of the marine air gun of the present embodiment includes a central high-pressure gas pipe 1, a signal line 2, an ignition line 3, a cable filling layer 4, a first wrapping layer 5, an inner sheath 6, a second wrapping layer 7, an armor Loading layer 8 and outer sheath 9.

[0044] See figure 1 and image 3, The central high-pressure air tube 1 includes a nylon tube 1-1, a braided layer 1-2, a tracheal sheath 1-3 and a buffer layer 1-4. The wall thickness of the nylon tube 1-1 is 1.0 to 2.0 millimeters, which is 1.5 millimeters in this embodiment. The braiding layer 1-2 has two layers, and the two braiding layers 1-2 are all braided by aramid yarn, and its weaving coverage rate is 85% to 95%. One layer of braided layer 1-2 is braided outside the nylon tube 1-1, and another layer of braided layer 1-2 is braided outside the previous layer of braided layer 1-2. The total thickness of the two braided layers 1-2 is 2.5 to 4.0 mil...

Abstract

The present invention discloses a marine airgun earthquake source cable. The cable comprises a central high-pressure air tube, a signal line, an igniting line, a cable filling layer, a first taped covering, an inner sheath, a second taped covering, an armor layer and an outer sheath. The signal line is arranged at the periphery of the central high-pressure air tube. The igniting line is arranged at the periphery of the central high-pressure air tube. The cable filling layer is encapsulated between the central high-pressure air tube and the first taped covering to fill the gap between the signal line and the igniting line. The first taped covering is wrapped at the outer portion of the cable filling layer. The inner sheath is coated at the outer portion of the first taped covering. The second taped covering is wrapped at the outer portion of the inner sheath. The armor layer is twisted at the outer portion of the taped covering through a plurality of steel wires. The outer sheath is extruded at the outer portion of the armor layer.

Description

technical field [0001] The invention relates to a marine exploration composite cable, in particular to a marine air gun seismic source cable used in a marine seismic exploration tow cable system. Background technique [0002] With the increase of the earth's population and the improvement of the quality of human life, more natural resources are needed to meet the needs of human production and life, which has led to the over-exploitation of land resources, and the energy crisis has become increasingly prominent. One of several central questions of the first century. The ocean covers two-thirds of the earth, and contains a large amount of solid mineral resources and petroleum resources. It will be the largest resource provider for human survival and development. The grim living situation forces humans to turn their attention to the ocean. However, so far, human exploration of the ocean has just started, and the understanding of the interior of the ocean and its bottom is stil...
