Functions of Online Operation System
The
CTU simulation and training system based on the layout of the site
equipment simulates the operation and conditions of CTU and displays the
overall unit and some key parts (BOP, stripper, injector, Christmas
tree, coiled tubing string, etc.):
For example:
Simulating the nitrogen gas lifting process with CTU
Simulating the sand removal and well flushing process with CTU
Simulating the fluid displacement process with CTU
Simulating the dragging acidizing process with CTU
Simulating the fracturing process with CTU
Simulating the fishing process with CTU
Simulating
the installation and disassembly of CTU, including installation of
lubricators, lifting of BOP and stripper, installation and removal of
downhole tools, controlling the main valve on the Christmas tree,
purging the fluid inside the coiled tubing with nitrogen, and
disassembly of the injector and ground manifold.

Operation and Simulation Functions of A Single Unit
Operation and Data Monitoring of the Main Unit
• CTU specification (different tubing size) and performance simulation
• Simulation of the CTU operations and display of corresponding simulation results
• Simulating injector operations
• Simulating the coiled tubing reel operations
• Simulating stripper operations
• Simulating the circulation system (fluid property) operations
• Simulating BOP operations
• Model of various downhole tools
• Simulating the tubing in-hole and out-hole operations
• Simulating the Christmas tree operations
Failure Simulation:
• Hydraulic system failures
• Well bore failures and tubing stuck
• Coiled tubing gets bent and damaged.
• Injector chain tension failures and traction failures
• Reel tension failures
• Stripper seal element leaks
• Pipe ram of BOP failure and leaks
……
The
system has built-in failure analysis function. According to Petrokh’s
years of site operation experience, the operation failures and equipment
running failures can be analyzed in real-time to provide corresponding
solutions.
