THE EXPERIMENTAL INVESTIGATION OF COMPLETION FLUID WORKING AS A GOOD THERMAL INSULATION IN THE DEEPWATER PRODUCTION WELL

摘要

For wells, risers and pipelines in offshore, the mechanical loads as well as the thermal insulation requirements normally increase with water depth. Hence, the traditional thermal insulation foam technology used in shallow waters and the associated design and test methodology may not be adequate to deep-water projects. This research focuses on investigation of a new material for insulation of deepwater wells and pipelines. In the research, many samples of insulation fluids are tested to find out attractive alternative to current fluids for deep water production. The paper highlights the development of these new thermal insulation fluid and its application in the lab. Compared to the current existing insulation fluids, these new insulation fluids provide high viscosity.
