An Advanced Coiled Tubing Simulator for Calculations of Mechanical and Flow Effects; Model Advancements, and Full-Scale Verification Experiments

摘要

An advanced simulator for investigation and planning of coiled tubing (CT) operations has been developed. In this paper, various models pertinent to the fluid flow within the CT and in the annular space between the CT and the well wall are presented, as well as various mechanical models pertinent to the placement of the CT in the well. Some verification tests have been carried out which match well to calculations by the simulator.
