Well logging truck hoists PKS–3,5E


Description

Well logging truck hoists are intended for carrying out round-trip operations upon geophysical survey in wildcat, exploration and production wells for oil and gas up to 7000 m deep with the logging cable maximal diameter up to 36 mm. The well logging truck hoist is mounted onto mobile platforms of all-terrain vehicles produced by URAL, KAMAZ, MAZ, IVECO and other manufacturers. The well logging truck hoist consists of the following parts:

  • motor vehicle chassis;
  • body;
  • tripping unit (TU);
  • free-running generator;
  • round-trip operations control system;
  • tool for measuring depth, speed and tension of cable;
  • spare parts and accessories kit.

The hoist can be operated at an ambient temperature range of –45°Ń to +50°Ń and at relative humidity of 80% at +15°Ń

    TU of a hoist is divided into the types:
according to the driver:

  • mechanical (M): (gear 2ŃŹÖ-4, mechanical differential, reverse gear);
  • hydraulic (H);
  • electrical (E).
according to the drum capańitance:
  • TUs are divided according to the operational depth of well inspection into (km): 2,0; 3,5; 5.0; 7,0.
according to the stuff winded on a drum:
  • logging cable (LC);
  • slickline (S);
  • rigid cable for horizontal wells development (HW);
  • combined: logging cable and slickline (CS).

The pattern of abbreviation: PKS-3,5E-CS (well logging truck hoist with electrical drive, for development of 3500 m deep wells, with winches for cable and slickline).

The equipment is provided by all permision documentation: vehicle type approval (VTA), permit for use, compliance certificate.

"GIspribor-M", CJSC carries on  maintenance service of all delivered equipment.
