Abstract
The invention relates to the technical field of petroleum drilling sidetrack drilling, in particular to a directional well section whipstock direction wireless measuring tool which comprises a body, a pressure control head located in the center of the body, a plurality of throttling ring spacer bushes and throttling rings sequentially arranged on the outer wall of the pressure control head in a sleeving mode. The outer wall of the upper end of the pressure control head is sleeved with a reset spring, the outer wall of the lower end of the pressure control head is sleeved with a flow guide spring seat, the lower end of the pressure control head is provided with a measuring rod upper ball seat, a measuring rod is installed in the measuring rod upper ball seat, the outer wall of the measuring rod is sleeved with a measuring rod lower ball seat, and the lower end of the measuring rod upper ball seat is provided with a stepped measuring cylinder which is positioned with the body through a circumferential positioning pin. The directional well section whipstock orientation wireless measuring tool is connected with a whipstock beveled body and an anchoring device, a circulating drilling fluid is used for pushing a pressure control head to move downwards, the pressure control head makes contact with a throttling ring in sequence to generate pressure waves, and the orientation of a whipstock in a directional well section or a horizontal well section is determined by calculating the number of the pressure waves. The problem that a wired cable car lowers the gyroscope inclinometer to be poor in applicability in a directional well section is solved.
