Flameless Heating Method

摘要

A method of cleaning a wellbore that may include pumping a process fluid through a flameless heating unit, controlling the flameless heating unit to heat the process fluid to a temperature in a range sufficient to chemically alter or induce phase change(s) to one or more deposits disposed in the wellbore, and transferring the process fluid from the flameless heating unit into the wellbore. Other steps may include using the heated process fluid to operate a tool, optionally by wireline operations, operatively disposed in the wellbore, whereby the heated process fluid and the tool work collectively to affect the removability of deposits. The flameless heating unit may include an internal combustion engine, a dynamic heat generator operatively connected to the internal combustion engine, and one or more pumps configured to provide a discharged fluid to the dynamic heat generator.

1. A method of cleaning a wellbore, the method comprising:
pumping a process fluid through a flameless heating unit within a dynamic heat generator; controlling the flameless heating unit to heat the process fluid, and, thereby, create a heated process fluid, to a temperature in a range sufficient to melt deposits formed in the wellbore; and transferring, subsequent to the controlling, the process fluid from the flameless heating unit into the wellbore.
