METHODS AND DEVICES FOR ANALYSIS OF FLUIDS IN WELL Russian patent published in 2010 - IPC E21B49/08 G01N7/00 

FIELD: measurement equipment.

SUBSTANCE: invention relates to analysis of the geological stratum fluids in the well for estimate and inspection of the stratum for the purposes of investigation and development of hydrocarbons production wells. The method and devices for analysis of stratum fluids in a well by way of separation (selection) of fluids from the stratum and/or borehole in the assembly for regulation of pressure and volume which is integrated into the flow line of the fluid analysis module and definition of isolated fluids characteristics. The required parametres may be deducted for stratum fluids in the static state and the undesirable stratum fluids may be drained and substituted with stratum fluids suitable for definition of characteristics or extraction of samples to the surface. The selected stratum fluids may be subject to circulation in the flow line circuit for definition of phase behaviour characteristics. Real time analysis of fluids may be performed under or almost under well conditions.

EFFECT: creation of method for analysis of stratum fluids in well by way of selection of fluids from the stratum and/or borehole into the analyser module flow line.
