Embodiment 1）

[0044] See Figure 1 to Figure 3 , the marine air gun seismic source cable that is easy to install in this embodiment includes a central high-pressure air pipe 1, a signal line 2, an ignition line 3, a cable filling layer 4, a first wrapping layer 5, an inner sheath 6, and a second wrapping layer 7. Armor layer 8 and outer sheath 9.

[0045] See figure 1 with 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...

Abstract

The invention discloses an ocean air gun source cable convenient to install. The ocean air gun source cable convenient to install mainly comprises a central high-voltage air tube, signal lines, ignition lines, a cabling filling layer, a first wrapping layer, an inner sheath, a second wrapping layer, an armoring layer and an outer sheath, wherein the signal lines are arranged at the periphery of the central high-voltage air tube, the ignition lines are arranged at the periphery of the central high-voltage air tube, the cabling filling layer is embedded between the central high-voltage air tubeand the first wrapping layer and fills gaps around the signal lines and the ignition lines, the first wrapping layer wraps the cabling filling layer, the inner sheath wraps the first wrapping layer, the second wrapping layer wraps the inner sheath, the armoring layer is formed by twisting a plurality of steel wires outside the wrapping layer, and the outer sheath is arranged outside the armoring layer in an extruded manner.

Description

[0001] The patent application of the present invention is a divisional application of the invention patent application with the application number 201610415257.2, the application date is June 14, 2016, and the invention name is "Ocean Air Gun Vibration Source Cable". technical field [0002] 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 [0003] 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 re...
