The invention discloses an experimental platform for measuring fluid state in an oil pipe. The experimental platform comprises a fluid storage device, a variable-frequency motor, a high-temperature gear oil pump, a first one-way valve, a proportional overflow valve, a throttling valve, a flow transmitter, a horizontal pipe section oil pipe, a high-temperature-resistant transparent glass horizontalpipe section, a bent section oil pipe and a high-temperature-resistant transparent glass elbow pipe, wherein the fluid storage device is connected with the high-temperature gear oil pump through a pipeline, and the high-temperature gear oil pump is connected with the variable-frequency motor and the first one-way valve separately; the first one-way valve is connected with the proportional overflow valve and the throttling valve through a three-way valve separately; and the throttling valve, the flow transmitter, the horizontal pipe section oil pipe, the high-temperature-resistant transparentglass horizontal pipe section, the bent section oil pipe, the high-temperature-resistant transparent glass elbow pipe and the fluid storage device are sequentially connected. The experimental platformis simple in structure, can simulate the fluid state of a bending section and a horizontal section in an oil field horizontal well, provides a stable flow field, can be repeatedly used and is accurate in experimental results.
