The invention relates to a stratification oil production logging instrument of a low-yield liquid oil well, mainly solving the problem that the existing logging instruments can not overcome degassinginfluence, causing bigger deviation of a measurement result. The invention is characterized in that a circuit barrel (1) is connected with a working barrel (2), a lower end-reducing current collectorcenter cylinder (3), an inner barrel (7), a support bar (4), a current collector drive device (5), a turbine flowmeter (6), a current collecting umbrella (9), a float switch (15), a booster spring (16), an oil-water interface detection array electrode (17) and a gas phase distributary channel (8), wherein the working barrel (2) is provided with an oil-water phase current collecting outlet (12) anda gas phase current collecting outlet (13), and the current collector center cylinder (3) is provided with a gas phase separating inlet (14) and an oil-water phase current collecting inlet (18). Thestratification oil production logging instrument of the low-yield liquid oil well can automatically control gas phase separation, thereby eliminating gas phase influence and reducing the deviation ofthe measurement result.
