Abstract
The utility model provides a marine oil exploration is with exploration cable with good function of blocking water, includes cable core and oversheath, has the transmission wire in the cable core, is equipped with aramid fiber reinforcement in cable core center, still is equipped with polyolefin filling rope and the oleamen that blocks water in the cable core, is equipped with the layer of the strip that blocks water between cable core and oversheath. The utility model has the advantages that the central part of the cable core is provided with the reinforcing piece made of aramid yarn with high tensile strength and small specific gravity, and the cable core is also provided with the polyolefin filling rope, thereby not only improving the tensile strength of the cable, but also leading the weight of the cable to be lighter; the water-blocking ointment is arranged in the cable core, and the water-blocking tape layer is arranged between the cable core and the outer sheath, so that the cable can block water in all directions in the longitudinal direction and the transverse direction, the water-blocking performance is enhanced, and the cable can be suitable for being used in seawater for a long time. Therefore, the utility model is used for the marine oil exploration is difficult for the infiltration, is difficult impaired, long service life as the exploration cable.
Description
Technical field
The utility model relates to a kind of signal-transmitting cable, the exploration cable that especially a kind of offshore oil drilling is used.
Background technology
The offshore oil drilling exploration cable, because environment for use is abominable, complicated, be in the seawater for a long time again, require cable to have advantages of higher tensile strength, can both block water in that vertical and horizontal are comprehensive, and weight is lighter, the performance of existing this cable is difficult to adapt to these requirements, easily infiltration, fragile influences useful life in the use.
Summary of the invention
In order to overcome the deficiency of existing offshore oil drilling with exploration cable, the purpose of this utility model provides a kind of offshore oil drilling exploration cable with good water stop function, tensile strength is higher, block-water performance is good, and weight is lighter, can adapt to environment for use abominable, complicated in the ocean, be difficult for infiltration, not fragile, long service life.
A kind of offshore oil drilling exploration cable that the utility model provides with good water stop function, comprise cable core and oversheath, has transfer wire in the cable core, be provided with the aramid fiber reinforcement in cable core central authorities, in cable core, also be provided with polyolefin gasket for packing and greasy for preventing water, between cable core and oversheath, be provided with water blocking tape layer.
The beneficial effects of the utility model are: owing to be provided with the reinforcement made from tensile strength height, aramid yarn that proportion is little in cable core central authorities, also be provided with the polyolefin gasket for packing in the cable core, both improved the tensile strength of cable, make the weight of cable lighter again; Owing in cable core, be provided with greasy for preventing water, between cable core and oversheath, be provided with water blocking tape layer, cable can both be blocked water in that vertical and horizontal are comprehensive, block-water performance strengthens, and can adapt in seawater to use for a long time.Therefore, the utility model is used for offshore oil drilling and is difficult for seeping water, being difficult for impaired, long service life as exploration cable.
Description of drawings
Fig. 1 is a cross sectional representation of the present utility model.
In Fig. 1,1, transfer wire, 2, conductor, 3, insulating barrier, 4, the aramid fiber reinforcement, 5, the polyolefin gasket for packing, 6, cable core, 7, water blocking tape layer, 8, oversheath, 9, greasy for preventing water.
Embodiment
With reference to Fig. 1, make transfer wire 1 at the conductor 2 outsourcing insulating layer coatings 3 that form by many copper wire bundle strands; With four transfer wires 1 and place four central authorities between the transfer wire 1 aramid fiber reinforcement 4, place the stranded together cable core 6 of making of polyolefin gasket for packing 5, greasy for preventing water 9 in the gap in four transfer wire 1 adjacent outsides; Outside cable core 6, coat water blocking tape layer 7, the oversheath made from two-sided waterstop 8 successively, promptly make the utility model.
