摘要： An oil-well metal pipe according to the present disclosure can be fastened with high torque even when the oil-well metal pipe has a large diameter. An oil-well metal pipe (1) according to the present disclosure has a pipe main body (10) including a first end portion (10A) and a second end portion (10B). The pipe main body (10) includes a pin (40) formed at the first end portion (10A), and a box (50) formed at the second end portion (10B). The pin (40) includes a pin contact surface (400) including an external thread part (41), and the box (50) includes a box contact surface (500) including an internal thread part (51). The oil-well metal pipe (1) according to the present disclosure also includes a resin coating (100) containing a resin, a solid lubricant powder, and copper phthalocyanine on or above at least one of the pin contact surface (400) and the box contact surface (500).
