COUNTER-PRODUCTIVE densitometer Oilfield WELL FLUIDS

摘要

1. The counter-productive liquid densimeter oilfield wellbore comprising a measuring unit switches the sensor computing unit and a hermetic casing provided with a receiving tube and switchblade connecting nodes, wherein the measuring unit is designed as a mechanical scales, equipped with a central counterweight and snubber bearing pairs abutments, and it consists of two chambers, the first and second, serially receiving the producing fluid flow, and the sensor output switching circuit coupled to the computing module, exc ichayuschiysya in that said chambers are uneven in shape and size, wherein the liquid phase duration set in the first chamber due to the weight flow rate of the fluid and the duration of dialing phase fluid into the second chamber due to the weight flow rate and density of the liquid odnovremenno.2. Counter-densitometer according to claim 1, characterized by the fact that its computing module adapted to automatically measure the durations of said phases, a series of accumulation cycles and dimensional periodic calculation flow rate and density of the liquid at the appropriate algoritmu.3. Counter-densitometer according to claim 1, characterized by the fact that the second chamber is provided with constant dimensional block additional weight for equalizing the absolute levels of liquid in said chambers at the lower fluid density.
