Geophysical cable

So, a geophysical cable is a cable for borehole testing (inclined and horizontal). It consists of current-carrying conductors, electrical insulation and two-layer armour. The purpose of the cable is to provide downhole instruments with power supply. In addition, the geophysical load-carrying cable serves as an information channel (i.e. a link) between downhole equipment and surface recording instruments, or helps to control the operating mode of all equipment. In addition, geophysical load-bearing armoured cables are used to lower and raise the equipment. In general, geophysical cable for wells is a multifunctional, almost universal cable: it is used for sampling of formation rocks and fluids, for shooting and blasting operations, for measuring the depth of a particular equipment at a certain point in time, etc.

How is the service life of a wellbore geophysical cable determined?

It is set as follows: it is the value of its run (measured in kilometres) through the block balance roller - until its first failure. According to the Russian standard, the established service life of a geophysical cargo cable is not less than 200 kilometres from the day of its commissioning to the first failure.

There is also such a notion as the service life of a cable for wells, before its utilisation, i.e. the period of time during which it retains its operational properties. Of course, the service life depends on many factors (conditions of use, proper handling, etc.) and, as a rule, ranges from one to one and a half years. By the way, the technical service life of the cable depends very much on the ratio of its diameter to the hoist winch drums (or block balance rollers). Used geophysical cable should be utilised.

It should be noted that launching a new geophysical cable with the device into the borehole should always be carried out with strict observance of all safety rules.

Now, what exactly can we offer you? High-quality geophysical (logging) armoured load-carrying cable of various grades: cable kgs, cable kg (cable kg1, cable kg3, cable kg7). All of them are presented in tables on our site, with the necessary characteristics.

During the operation of geophysical cable, you need to pay great attention to the quality of its maintenance. This concept includes:

• cable lubrication; 
• regularly checking the condition of the cable; 
• cleaning the cable of flushing fluid; 
• troubleshooting the cable; 
• timely repair of the cable.

Compliance with these requirements will significantly increase the service life of the well test cables you purchase.

• The first indicator in its name is its properties (i.e. a cable with the letters KG is a load-carrying cable); 
• The second indicator is the number of conductive cores in the cable (for example, cable kg1 contains one core);
• The third indicator - shows the value of breaking force;
• The fourth indicator is the maximum operating temperature of the cable;
• The fifth indicator shows the presence of the outer sheath.

Thus, if we take a specific example, the cable KG1 x0,75-18-150 has these qualities: it is a geophysical load-carrying single-core cable, with a breaking force of 18 kN, and the maximum temperature of the working environment up to +150 degrees centigrade.

We want to note that cable KG1 x0,75-55-150 PO, cable KG3 x0,75-40-150 PO, cable KG9 x0,75-30-150 PO, cable KGL1 x0,75-20-150 PO - have a sheath.

Without geophysical load-carrying cables can not do without in many cases, so it is not surprising that when buying them to them are very high requirements.
