The invention relates to the technical field of while-drilling and directional
logging, in particular to a flow guide head mounting structure for
electrical connection, which comprises a
drill collar, a flow guide head and an elastic
gasket, a first through hole for fluid to pass through is defined by a first hole wall of the
drill collar, and a step surface is convexly arranged on the first hole wall; the flow guide head is installed in the first through hole and provided with a matching face matched with the step face in a stopping mode, the elastic
gasket is installed in the first through hole and abuts against the flow guide head in the first direction, and the elastic
gasket elastically deforms towards the step face in the first direction under the action of locking force so as to fasten the flow guide head to the
drill collar. The flow guide head is positioned through the step surface, and then the flow guide head is limited and fixed between the step surface and the elastic gasket through the elastic gasket, so that the step surface can be set to be smaller, the flow field is uniform, the pressure drop is small, the
machining requirements of the flow guide head, the drill collar and the elastic gasket are lower, the
machining and assembling difficulty is reduced, the cost is reduced, and the mounting efficiency is improved.
