Well logging truck hoists PKS- 5G
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 of up to 36 mm. The well logging trcuk 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;
- 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°Ñ to +50°Ñ and at relative humidity of 80% at +15°Ñ
TU of a hoist is divided into the types:
according to the driver:
- mechanical (M): (gear 2ÑÊÖ-4, mechanical differential, reverse gear);
- hydraulic (H);
- electrical (E).
- TUs are divided according to the operational depth of well inspection into (km): 2,0; 3,5; 5.0; 7,0.
- 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.
