Zusammenfassung:The invention provides a flow-regulating and water-controlling tubular column with a horizontal well fluid production profile monitoring function. The flow-regulating and water-controlling tubular column comprises a base tube; the casing pipe is arranged outside the base pipe in a sleeving mode, and perforation holes are formed in the casing pipe; the packers are arranged between the base pipe and the casing pipe at intervals, and the packers are used for packing an annular space between the base pipe and the casing pipe; the sand control screen pipes are arranged on the base pipe in a sleeving manner at intervals and are positioned in the annular space; the liquid production profile monitoring devices are arranged between the adjacent sand control screen pipes; the flow adjusting and water controlling device is mounted on the base pipe and corresponds to the liquid production profile monitoring device in the axial direction; wherein the fluid production profile monitoring device is constructed to be capable
