Abstract
The utility model provides a deep well cable for oil exploration, a serial communication port, including conductor, insulating layer, filler, tie layer, inner layer armor steel wire layer and outer armor steel wire layer. The utility model discloses can be used to during operations such as logging, perforation, coring of all kinds of oil gas wells on land and ocean, electrical connection between ground instrument and the instrument in the pit.
Description
Technical Field
The utility model belongs to the technical field of wire and cable's technique and specifically relates to a deep well cable for oil exploration.
Background
In the mineral exploitation industry of China, the early stage is mainly exploration, including oil reservoirs on land and sea. For the petroleum buried layer, the buried layer is generally located several hundreds to several kilometers below the ground, so that the cable for deep well petroleum exploration is needed to be provided for electrical connection between ground instruments and downhole instruments when the cable is used for logging, perforating, coring and other operations of various oil and gas wells on land and in the sea.
Disclosure of Invention
An object of the utility model is to provide a deep well cable for oil exploration, when can be used to deep well stone, gas field exploration, connect the use of ground and the tester in the pit.
In order to realize the purpose, the technical scheme of the utility model is that: the cable for deep well petroleum exploration is characterized by comprising a conductor, an insulating layer, a filler, a tie layer, an inner armored steel wire layer and an outer armored steel wire layer.
The conductor is formed by combining tinned fine soft copper wires.
The insulating layer is made of insulating ethylene propylene diene monomer rubber.
The material of the filler is natural fiber.
The band layer is a double-layer band and is respectively a polyester band and a rubber cloth band.
The inner armor steel wire layer and the outer armor steel wire layer are both made of high-strength galvanized thin steel wires.
The ratio of the diameter of the steel wire of the inner armor steel wire layer to the diameter of the steel wire of the outer armor steel wire layer is 1: 1.2.
both the conductor and the insulating layer form a conductive core.
The number of the conductive wire cores is seven.
Compared with the prior art, the deep well cable for oil exploration has the advantages that: the utility model discloses in through the structure that adopts conductor, insulating layer, filler, band layer, inlayer armor steel wire layer and outer armor steel wire layer, can improve the pulling force of whole cable to when can be used to the operation such as logging, perforation, the coring of all kinds of oil gas wells on land and ocean, the electrical connection between ground instrument and the instrument in the pit.
Drawings
Fig. 1 is a schematic cross-sectional structure of the present invention.
In the figure, 1, a conductor; 2. an insulating layer; 3. a filler; 4. binding a belt layer; 5. an inner armor steel wire layer; 6. the outer layer is armored with a steel wire layer.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in figure 1, the deep well petroleum exploration cable comprises a conductor 1, an insulating layer 2, a filler 3, a band layer 4, an inner armor steel wire layer 5 and an outer armor steel wire layer 6.
The conductor 1 is formed by combining tinned fine soft copper wires.
The insulating layer 2 is made of insulating ethylene propylene diene monomer rubber, and in the embodiment, the insulating layer 2 is formed by extruding commercially available insulating ethylene propylene diene monomer rubber.
The filler 3 is made of natural fibers; in this embodiment, the filler 3 is a string made of natural fiber, and the string is a commercially available product.
The band layer 4 is a double-layer band which is respectively a polyester band and a rubber cloth band.
The inner armor steel wire layer 5 and the outer armor steel wire layer 6 are both made of high-strength galvanized thin steel wires; in this embodiment, the inner armor steel wire layer 5 and the outer armor steel wire layer 6 are of a concentric structure.
The ratio of the diameter of the steel wire of the inner armor steel wire layer 5 to the diameter of the steel wire of the outer armor steel wire layer 6 is 1: 1.2.
in the embodiment, considering that the cable bears certain tensile force, an inner-layer and an outer-layer high-strength thin steel wire armoured structure which are mutually contacted are adopted, and the diameter of the steel wire of the outer layer is slightly larger than that of the steel wire of the inner layer.
Both the conductor 1 and the insulating layer 2 form a conductive core; the number of the conductive wire cores is seven.
The maximum well depth of the cable can reach 5500 meters.
The above components are all standard components or components known to those skilled in the art, and the structure and principle thereof can be known to those skilled in the art through technical manuals or through routine experiments.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
