摘要： In the preferred embodiments of the invention disclosed herein, new and improved fluid-investigating tools adapted for positioning in a production well are respectively provided with a selectively closed chamber adapted to entrap a representative sample of the well fluids flowing past the tool so that the fluid phases of different densities will become segregated. The tools are uniquely arranged to provide surface signals which are representative of the density of the segregated fluid phases at discrete intervals in the sample chamber for determining the volumetric proportions and densities of the well fluids.
