The invention discloses an omniseal suspension support of an automatic vertical drilling tool. The omniseal suspension support comprises a detection protection mechanism, a front oil chamber supporting mechanism and a rear oil chamber compensation mechanism which are sequentially arranged in a tool outer barrel inner cavity of the automatic vertical drilling tool from top to bottom along a mandrel outer circle. A suspension adjusting mechanism is arranged on the periphery of the front oil chamber supporting mechanism and the periphery of the rear oil chamber compensation mechanism. The lower end of a mandrel is in transmission connection with a slurry turbine generator and a measuring, control and storing unit through screws. According to the omniseal suspension support, lubricating oil is injected into the suspension support, the suspension support bears suspension axial force of a whole electronic short section and a control shaft, a tool system circuits are rapidly detected, data stored by a tool system is read, slurry is prevented from entering the support, and the straightness of a whole shaft system after assembling is ensured; and the structure is compact, and operation is reliable.
Description
technical field [0001] The invention belongs to the technical field of mechanical equipment and relates to a fully sealed suspension support of an automatic vertical drilling tool. Background technique [0002] During the drilling process, the anti-deviation and quick drilling of high-steep structures and high-dip formations in the piedmont has always been one of the main problems in oil and gas drilling engineering. The automatic vertical drilling tool is an independent deviation correction, The drilling tool system with stable deviation can effectively solve the problems of preventing deviation and driving fast, which plague the drilling engineering field. However, the automatic vertical drilling tool needs to quickly detect the circuit before the downhole operation, and the shaft system of the key unit of the system should be easy to install and support; moreover, when the automatic vertical drilling tool is in the downhole operation, some of its units are soaked in the m...
