Problems solved by technology
[0002] In order to meet the domestic development of deep gas and shale gas, as well as the development of highly complex and geologically uncertain wells in foreign countries such as the Middle East, South America, and Russia, today's drilling rigs are faced with the challenges of ultra-deep wells, long horizontal wells, and directional wells with a depth of more than 7,000 meters. Development, at present, domestic ultra-deep well drilling rigs mostly adopt vertical column or single triangular column structure, which has poor stability and is not easy to adjust

The invention discloses an ultra-deep well drilling machine base convenient to adjust. The center of the bottom of a winch beam is connected to the output end of a hydraulic cylinder through a hydraulic rod; the hydraulic cylinder is fixed on a drilling platform; a plurality of supporting assemblies are further arranged between the winch beam and the drilling platform; a supporting plate is hingedto a fixed seat; one end of a threaded sleeve is connected to a sleeve plate in a in threaded mode, so that the sleeve plate reinforces and supports the winch beam; an inner rod is connected to the inside of the threaded sleeve in a threaded mode; one end connected to the sleeve plate, away from the threaded sleeve, of the inner rod is connected with a vertical conical gear; the vertical conicalgear meshes with a horizontal conical gear; and the horizontal conical gear is installed on the output end of a rotating motor through a vertical rod. The drilling machine base supports and lifts thewinch beam through a hydraulic device, meanwhile, the winch beam is supported by the supporting assemblies in an assisting mode, and the threaded sleeve penetrates through the sleeve plate to strengthen the support effect of the supporting assemblies, so that the stability of supporting the winch beam by the supporting assemblies is better.
Description
technical field [0001] The invention relates to the technical field of drilling rig bases, in particular to an ultra-deep well drilling rig base that is convenient for adjustment. Background technique [0002] In order to meet the domestic development of deep gas and shale gas, as well as the development of highly complex and geologically uncertain wells in foreign countries such as the Middle East, South America, and Russia, today's drilling rigs are faced with the challenges of ultra-deep wells, long horizontal wells, and directional wells with a depth of more than 7,000 meters. Development, at present, domestic ultra-deep well drilling rigs mostly adopt vertical column or single triangular column structure, which has poor stability and is not easy to adjust. Contents of the invention [0003] The object of the present invention is to provide an ultra-deep well drilling rig base that can be easily adjusted to solve the problems raised in the above-mentioned background te...
