Product Overview
The 80K Skid Mounted Coiled Tubing Unit is a heavy-duty modular four-block CT workover system, split into independent Power Skid, Lifting Control Cabin Skid, 80K Injector Skid and Large-Capacity Tubing Reel Skid. Separated skid design allows individual container/truck transportation, perfectly adapted to mountain, desert, narrow-road remote well sites with limited space.
Powered by genuine CAT C13 520HP inline six diesel engine matched German STIEBEL transfer box and PARKER closed hydraulic system, the unit delivers 80,000 lbs continuous pulling force and 40,000 lbs snubbing thrust, the highest pulling capacity of our standard skid CT series. It is equipped with 4-1/16” 10,000PSI full NACE anti-H2S well control stack, supporting 1.5” OD coiled tubing with max storage capacity up to 6500 meters.
The whole unit complies with SY/T industry standards, API Spec 6A, NACE MR-01-75 and ISO9001 certification. Integrated MEDCO tubing fatigue analysis DAS system, dual CCTV real-time monitoring, full hydraulic hose reels and self-contained fuel/hydraulic tanks are standard configuration. Stable operation range covers -29°C ~ +45°C, widely used in deep well milling, acid fracturing, nitrogen stimulation, snubbing, underbalanced drilling and sour gas reservoir treatment.

Seven Core Product Advantages
Four Independent Modular Skid Layout, Flexible Transportation & Fast Rig-Up
Split into four separated heavy-duty steel skids with standardized lifting lugs, each can be transported separately by flat truck or standard container, solving the access restriction of narrow mountain roads and compact well pads. All hydraulic & electrical circuits adopt quick plug connectors with dust caps, cutting on-site assembly time greatly without complicated pipeline wiring.
CAT C13 Genuine High-Power Diesel Power Unit
Original CAT C13 six-cylinder industrial diesel engine provides stable 520HP heavy power output, matched three-in-one composite radiator to cool engine water, fuel and hydraulic oil simultaneously, guarantee stable full-load operation under +45°C high temperature. Heavy-duty STIEBEL transfer box evenly distributes power to multi-group PARKER hydraulic pumps, ensuring sustained 80,000 lbs pulling force under long-hour heavy tubing load.
80,000 Lbs Super Heavy-Duty Injector for Deep Well Operation
80K high-load injector adopts imported diamond chain, Rexroth reducer and Linde hydraulic motor. Ultra-wide adjustable speed range from 0.3m precise creep speed up to 66m/min fast running speed, meeting both precise logging and high-efficiency deep well pulling work. Built-in electronic load sensor displays real-time tubing tension weight, effectively prevent tubing overload breakage risks.
Full NACE Anti-H2S 10,000PSI Well Control Stack for Sour Oilfields
Complete well control assembly includes integral quad ram BOP, side door stripper and segmented lubricator. All fluid-contact metal materials comply with NACE MR-01-75 anti-sulfur standard, perfectly suitable for high H2S content sour gas wells. Rated working pressure 10,000PSI with factory 15,000PSI hydrostatic test pressure, fully satisfy high-pressure fracturing & snubbing safety requirements.
Large Capacity 6500m 1.5” CT Reel Skid
123-inch large flange reel design supports maximum 6500 meters 1.5-inch coiled tubing storage, reducing repeated tube transfer work for ultra-deep well construction. Equipped STONE 15,000PSI rotary joint, EDD high precision flowmeter and PARKER pressure relief valve; dual mechanical & electronic counter ensures accurate depth recording, automatic forced level wind avoids tube overlapping and abrasion.
