SUBSTANCE: invention can be used in control means for cable motion parameters reading and digitising in various hardware and processing systems.

The invention relates to enclosed in long assemblies flexible lines mechanical connection and can be used in the means of verification for the digitization and characterization of the movement of the cable in a variety of technical and technological systems, and can be used in mining, construction, oil and gas and processing industries, river and sea transport, housing and communal sphere, science, aviation and other branches of industry as towing, lifting or tension element tether systems, as well as where there are mechanical rope systems with feedback and active-control parameters of movement of the cable.
Measurement of parameters of movement of the cable and active management of this movement in the framework of the technological or technical process is in great demand in industry. Now possibilities of information and digital technologies allow to accurately calculate any process and actively control. Problem is the only equipment of the rope to the parameter relative to which the costs. For example, the measurement of the depth of the well is one of the necessary components of geophysical and drilling works. Increasing the accuracy of measurements of depths allows to improve the quality of interpretation of logging information, reduce time and cost of drilling operations.
Currently measurement of the depth of the well is carried out by tagging wireline magnetic marks on pieces with the subsequent removal of signal processing and magnetic labels (MM) when lowered into the borehole rope with downhole equipment. Eat signal contactless. This method, in combination with mechanical, is the main when measuring depths by logging cable, MM when affixed every 10 m are made a point of accurate reading of depths, and in the intervals of interpolation between the marks depth is determined by measuring the roller block-balance.
Known «Method of echo sounding depth of the downhole device when logging studies in wells» (patent RU 2172832, 21 47/04, publication date: 27.08.2001,), selected as a prototype, the task of which is to expand the functional capabilities by increasing the precision of determining the depth. In the way the pre-break logging cable (GPC) at identical intervals. To denote segments put on the armor of GPC MM, distributing them to the length of cut. These MM represent a sequence of stations of various degree of magnetization armor GPC. Fix the downhole tool at the end of the GPC, and send it into a hole. Discover MM on a moving GPC by reading the reader. When detected, MM GPC register border of the segments on record logging curve. Determine the number of detected MM and calculate the depth of the descent of the downhole device on the proposed mathematical expression.
Disadvantages of the method is that when automatic data binding logging to the true depth of the wells, especially during the registration in the digital form, this method does not provide neither the accuracy of determining the depth or reliability of readout, no long-term work marks. Break manually with high accuracy cable length over a kilometer on the exact every 10 meters is very difficult. Read the tag depth at the drill is difficult due to large differences in field strength labels, a wide range of cable speed and high tension external magnetic fields influence of demagnetization influence of casing pipes, bends in the pulleys and excessive tension of the wireline, which leads to a decrease of an amplitude of labels and accumulating errors. When the distance between the cable and the sensor cell, which is especially common when the slopes of the cable into the well through the suspended blocks, field strength, magnetic marks a point of reading them may further decrease in 4-5 times.
As more and downs cable field strength magnetic labels falls and decrease below the threshold sensor arises the need to re-echo sounding of the cable to resume the initial field strength labels. During the works in the deep (the ultra-deep) and/or cased borehole field strength magnetic labels due to increased mechanical and thermal impacts and/or magnetization casing decreases rapidly. This increases the frequency markup cable.
When logging oil and gas wells length of the segments at a marking of load-bearing logging rope is selected from a series of 10, 20 or 40 PM So if omitted or false detection of a magnetic label error echo sounding depth can reach tens of meters, and the required accuracy echo sounding depth downhole tool in the hole is estimated to be 1 see To resolve this contradiction is taking further measures to improve the accuracy echo sounding depth of the well apparatus based on increasing the volume of carried out the field measurements, which is connected with big expenses of time and means.

The appointment of a magnetic mark - to increase the accuracy of the speed and extent of the movement of the cable.
In 1 magnetic labels in the cable is used, at least one magnetic thread 4 installed, at least one outer strands 3, which is wound around the inside strands 5. Similarly, at least one such magnetic thread can be equipped with braid armour) cable. It is possible to install a single strand 3 and/or various strands of several magnetic threads 4 with different properties, for example, two threads 4, one with the properties of a permanent magnet, and the other for magnetic recording labels induction, which additionally, you can record any information, as the recording wire.
In the composition of the magnetic threads 4 can be dispersed magnetic powder (primarily non-metallic threads), or use a thread of a wire made of flexible permanent magnet, or of magnetic wire, which you can record the signals in the form of magnetic labels as the recording wire.
Cable 2 magnetic thread 4, installed in the outer strands 3, are manufactured at the production of cables. Depending on the purpose of the rope and strand method, the number of magnetic threads 4 may be different. Production of cables allows to synchronously equip in each outer strands one magnetic thread 4, which will increase the read signal. During the production of rope at least one any thread for outer strands 3 is replaced by the magnetic thread 4 with the properties of the permanent magnet and/or for recording and playback of signals in the form of magnetic labels.
The basis of the rope 4, consisting of threads, collected in 3 strands, hair strands suites in the cable 4 spiral with a certain step around core 1, and in a linear plane with the movement of the cable rib any strands, including 3 strands with magnetic thread 4, according step spiral strand, periodically passes across the surface of the rope, over which the installed magnetic sensors 6 for recording and/or playback the magnetic labels that allows the reader to receive a signal that handles the processor and generates the necessary information on the speed and/or extent of movement of the cable. The pitch of the spiral winding of locks is constant throughout the length of the cable varies with the load a little, he is the main technical characteristics, which are calculated speed and length of travel.
To maintain the high parameters of the magnetic labels on the cable it periodically or each lifting operation automatically update the magnetic threads recorded magnetic label, and recorded magnetic marks on the magnetic threads must have a complex signal, which will allow clearly to distinguish the background and signal interference from magnetic label. This will increase the accuracy of measurements.
When the location of the multi sensor indicator reading the magnetic labels in a ring around the rope, one can accurately automatically determine the accuracy of moving of cable and speed of movement of the cable is determined by the linear arrangement of sensors. At the equipment of system feedback, you can actively support-set options in speed and accuracy of moving of the cable in the mechanical system.
