n: The two symmetric troughs manufactured in blank bits. Be convenient for clicking and breaking when desorption of drill bit.

n: the stabilizer whose slices for setting upright are fixed in the steel trough using screws and bonds

n: the sensing equipment which can measure the flowing state of the drilling fluid in the aerial trough

n: the rubber protection valve on whose outskirt there are several flowpath trough which benefits the fluid flowing

n: the drive rod on the top ofdrilling pipe of small rig，with troughs in the outskirt and able to move in the cirulator propelling the pipe moving

n: a flexure of rock strata (e.g., an arch or a trough) produced by horizontal compression of the earths crust. See anticline, syncline.

a bend-like disruption in a rock strata such that the angle of the formation is significantly changed.

n: a trough or pipe that is placed between the surface connections at the wellbore and the shale shaker and through which drilling mud flows on its return to the surface from the hole. Also called flow line.

n: a though or pipe through which the mud being circulate up the annulus is transferred from the top of wellbore to the shale shakers (q.v.).sometimes calledflowline.

n: on an engine, a steel trough-like attachment fitted to the bottom of the engines crankcase. The engines oil pump picks up oil from the pan and circulates it through the engine.
