Abstract

The invention relates to an oil field steam injection boiler steam dryness measurement method and its system. The measurement method employs a process 1 and a process 2 alternately. The process 1 includes: measuring a conductivity value a by a first conductivity sensor (6), then conducting commutation, measuring a conductivity value b by the first conductivity sensor (6), and calculating a dryness value by a programmable logic controller (8). The process 2 includes: measuring a conductivity value c by a second conductivity sensor (7), then conducting commutation, measuring a conductivity value d by the second conductivity sensor (7), and calculating the dryness value by the programmable logic controller (8). The oil field steam injection boiler steam dryness measurement method and its system provided in the invention improve the accuracy and stability of oil field steam injection boiler steam dryness measurement, and reduce the use cost.

Description

technical field [0001] The invention relates to the design of a boiler dryness measuring device, and in particular provides a method and a system for measuring the steam dryness of an oil field steam injection boiler. Background technique [0002] The steam injection boiler is used as a steam generator for injecting steam into the oil layer during oilfield exploitation. It will force the steam generated into the underground oil layer to provide heat source for the thermal recovery of heavy oil. Its combustion operation quality and output steam quality are closely related to the heat injection effect. Dryness refers to the mass percentage of dry saturated steam contained in wet saturated steam, which is an important parameter for the safe operation of steam injection boilers and an important indicator affecting the thermal recovery effect of heavy oil. In order to ensure the effectiveness, economy and safety of equipment operation, higher and higher requirements are put forwa...
