Abstract
The invention relates to an operation method for safe hoisting of a drilling machine derrick. The method successively comprises the steps that (1) a well mouth base and a drilling platform are installed, and an A-bracket is installed on the well mouth base; (2) a derrick main body is pieced together, wherein the lower end of a derrick supporting leg is firstly hinged on the well mouth base by a derrick large pin, and then the derrick main body is pieced integrally from bottom to top and maintained horizontal; (3) an overhead crane and a racking platform are installed, and a hook block assemblyis placed; (4) a drilling line between an overhead crane wheel set and a block assembly wheel set is put through, a live line head of the drilling line is led downwards from an overhead crane guide wheel and led onto a winch drum after bypassing a drilling platform guide wheel, and the other end of the drilling line is fixed on a drilling line fixation device which is located under the front sideof the derrick main body; (5) a back like is led out downwards from the hook block assembly and fixed on a back line fixation lug after bypassing a derrick guide wheel and an A-bracket pulley; and (6) a winch is started to unreel the drilling line to drive upward moving of the hook block assembly, the back line is pulled by the hook block assembly, and the back line drives the derrick main body to be vertical. The method has high operation efficiency and high safety.
Description
technical field [0001] The invention relates to a drilling auxiliary equipment, in particular to a drilling derrick safe lifting operation method, which belongs to the technical field of drilling equipment. Background technique [0002] The derrick of the drilling rig is composed of a drawworks, a derrick, a crown block, a traveling block, a hook and a wire rope, etc. The derrick is mainly composed of the main body of the derrick, a herringbone frame, a crown block platform, a second floor platform, a working ladder, a riser platform, a drill floor and a wellhead base It is mainly used to place and suspend lifting equipment and tools such as crown block, traveling block, hook, lifting ring, hydraulic and pneumatic tongs, hydraulic buckle, lifting tongs, and elevators. In addition to bearing its own load, the derrick also bears the hook load, wind load, and vibration load generated when the drilling rig vibrates when lifting and lowering the drilling string. [0003] The mai...
