Description
The utility model belongs to the seafari exploitation and measures the cable technology field, is mainly used in marine multi-wave seismic exploration data acquisition and transmission.
In the marine oil and gas resources exploration, no matter seismic prospecting commonly used is that two dimension or 3-d seismic exploration all will use data transmission cable, it is actually the transmission medium of seismic exploration data and order, is called for short submarine cable, and english abbreviation is OBC (Ocean Bottom Cable).
The land seismic prospecting cable that we use always is because of itself water pressure resistance, anticorrosion and abrasion resistance properties is relatively poor can't be used for marine seismic prospectiong.Marine seismic prospectiong is the same with land seismic prospecting, all requires cable should have certain mobility, is put mobile needs to satisfy by Reconnaissance Survey.Land seismic prospecting generally adopts the connector mode of dismounting stube cable to rearrange the cable position, moves needs to satisfy measuring point, and is fixing deposited not in the seabed with Yu Haiyang electric power transfer and communication signal transmission cable, can't satisfy the removable needs of measuring point.Now, use buoyant cable more widely, though can satisfy the measuring point movement requirement, can only record simple component is single wave datum signal.Though the cable that many components are many wave datum signal can be gathered in the existing existing seabed that sinks to, but because of many openings are arranged on the cable sheath, be connected to a plurality of taps in the above and bundle detectors such as wave detector is arranged, be difficult for dragging, have influence on the image data efficient that measuring point moves in the seabed.
The purpose of this utility model be to provide a kind of water pressure resistance, anticorrosion, wear-resistant, water-stop is good, intensity is high and can sink to the removable data transmission cable in seabed, it can be used for marine seismic prospectiong, realizes the data acquisition and the signal transmission of multi-wave seismic under seabed exploration.
The utility model is realized as follows.
Each root finished cable two ends is provided with watertight connector, and watertight connector one end is provided with and protects the cable spring, is used to protect data transmission cable, and its other end is provided with the multi-pin connector that contains internal thread and sealing, is used to connect the outside hydrophone and wave detector and the electronic unit that sink to the seabed.Data transmission cable is made up of cable core, inner restrictive coating, tension reinforcement, external sheath layer.Cable conductor is provided with two logarithms and passes line and a pair of power line; the space is filled with gasket for packing around number passes line and power line; it is inner restrictive coating that the shaped back of gasket for packing has been extruded insulating barrier in its outside; be provided with armour in the inner restrictive coating outside; form formation tension reinforcement for inside and outside two layers of steel wire are stranded; extruding the anti abrasive insulating barrier of one deck waterproof anti-corrosion in the armour outside is external sheath layer, is used to protect cable conductor and armour.
The utility model has following advantage.
The utility model is compared with telecommunication cable with existing non-moving type sea electric power cable has the intensity height, can power and transmit the characteristics of seismic signals simultaneously.Cable is non-leakage when the work of 200 meters seabeds of the depth of water, but anticorrosion and mobile operating do not drift about.This cable is compared with the single ripple floatation type cable commonly used of marine seismic prospectiong at present, has to sink to the seabed, can also can gather characteristics such as multi-wave seismic data by drag operation.
