dilution control system for a sample degasser, degasser system and drilling fluid data profiling method

摘要

A degassing system may comprise a mass flow controller device and a sample pump coupled to a sample degasser for controlling the dilution of gases extracted from the drilling fluid in the sample degasser by a dilution fluid such as nitrogen gas. The mass flow controller can inject the dilution fluid into the sample degenerator tank to dilute the gases extracted from the drilling fluid. The dilution fluid may be aspirated or sprayed on the sample degasser. The sample pump may extract a sample of the gases separated from the drilling fluid by the sample degasser. The dilution fluid injection rate in the sample degasser and the drilling fluid gas sample extraction rate can be adjustable to control the dilution of the gas sample for analysis.
