Product Overview
Coiled tubing lubricator is a critical well control component matched with quad ram BOP and side door stripper, installed above blowout preventer to form sealed tubing running channel during CT intervention. It isolates wellbore high-pressure fluid, prevents liquid/gas leakage when coiled tubing enters and exits wellhead, guarantees safe snubbing, acidizing, plug milling and fracturing operations.
We supply three mainstream specifications: 4-1/16" 10K, 5-1/8" 10K, 5-1/8" 15K lubricators. All wetted metal materials strictly comply with NACE MR-01-75 anti-hydrogen sulfide standard, suitable for conventional and sour oil & gas wells. Adopt standard male-female union connection for fast on-site assembly, independent segmented splicing design, flexible length matching per wellsite requirement. Working pressure covers 10,000PSI and 15,000PSI grades, matching 40K/60K/80K/100K modular skid coiled tubing units of different pulling loads (80K heavy-duty CT rig available).

Core Product Advantages
Full NACE MR-01-75 Anti-H2S Design
All metal parts contacting well fluid adopt anti-sulfur alloy material, pass strict sulfide stress cracking test, long-term stable service in high H2S sour gas reservoirs, fully comply with oilfield HSE safety standards for sour well operation.Two Pressure Grades for All Working Conditions
10,000PSI standard version fits conventional medium-pressure cleanout & acidizing jobs; 15,000PSI high-pressure version specially customized for ultra-deep well fracturing, with 1.5 times hydrostatic test safety margin, zero leakage under long-duration high-pressure construction.Two Bore Sizes for Full CT Fleet Matching
4-1/16" small bore matches 1.5"~2" small coiled tubing and 40/60K light-duty CT unit; 5-1/8" large bore adapts 2"~3.5" heavy tubing, compatible 80K / 100K heavy-duty coiled tubing equipment, covers all mainstream well service fleets.Standard Male-Female Union Quick Connection
CB44 / CO54 / CO56 industry standard male & female union joints, perfectly dock with matching quad BOP and side door stripper, no custom adapter required, drastically shorten wellhead rig-up time.Segmented Combination Structure
Modular split design, freely combine 4ft / 8ft single sections to adjust total lubricator height according wellhead height and operation demand, convenient transportation and storage when disassembled.High-Pressure Sealing Reliability
Precision machining inner bore, matched special high-pressure anti-aging sealing components, resistant to high temperature, low temperature and corrosion, maintain stable sealing performance under long-term continuous tubing running.Application Scenarios
