Coiled Tubing Work and Service
At present, the company is equipped with two sets of advanced coiled tubing operation units, namely vehicle-mounted and skid-mounted. Through advanced coiled tubing equipment, a high-quality service team, a complete set of downhole operation tools, a powerful technical support system and scientific and standardized management, it can carry out sand flushing, unblocking, negative pressure return drainage and salvage operations. Moreover, it can provide coiled tubing drag acidizing, sandblasting perforation fracturing, switch sliding sleeve fracturing, logging and jet radial drilling services.
Coiled tubing Nitrogen Flowback
It can be used for inducing injection when new Wells are put into production, testing for production, and the return of well pressure fluids (including residual fluids and fracturing fluids).
Features:
- Compared with conventional suction and air lift methods, it is safer and more reliable, has a shorter operation cycle and higher efficiency;
- Continuous unloading gradually reduces the back pressure at the bottom of the well, minimizing damage to the oil layer.
- The gas injection volume and liquid discharge speed can be adjusted, making construction convenient and flexible with high controllability.
Coiled Tubing Fishing
The fish that have fallen from the bottom of the well can be retrieved, including the oil pipe, casing, drill pipe, bridge plug, bottom well motor, wire rope section, cable section and the coiled oil pipe itself.
Features:
- It generates significant axial tensile or impact forces in vertical Wells or highly inclined Wells, especially in horizontal Wells, facilitating the removal of trapped objects from underground Wells and enhancing the success rate of salvage operations;
- During the salvage process, various flushing fluids, including nitrogen and acid, can be circulated to conduct well cleaning and salvage simultaneously, preventing the falling fish from being stuck again;
- The top of the fallen fish can be subjected to high-pressure flushing, spraying or dissolving of sand, mud, scale and other debris before being caught, and the catching effect is good.
Coiled Tubing Logging
Logging cables are inserted into coiled tubing, equipped with corresponding downhole tools and joints, and connected to logging instruments. The logging instruments are then sent to horizontal Wells or highly deviated Wells for testing. It can be applied in logging processes such as production logging and open-hole logging, and can simultaneously pump liquids to achieve circulation.
Features:
- It can transport well logging instruments over long distances in large slopes and horizontal Wells;
- It enables logging tools to pass through short-distance helical twisted pipe sections;
- Better protection of logging cables, quick, simple and convenient replacement of logging tools;
- It can operate under pressure or with liquid flow, and is safe and reliable.
