Abstract

The invention relates to a drilling tool combination design method for improving drilling efficiency and collecting open hole information in the vertical drilling process. The drilling tool combination structure comprises an information storage short section, a bypass valve assembly, an anti-falling assembly, a motor assembly, a cardan shaft assembly and a transmission shaft assembly from top to bottom. The transmission shaft assembly of the screw drilling tool is provided with a mechanical pushing type vertical drilling short section, a hydraulic impact device and a transmission assembly from top to bottom. An information storage short section, a bypass valve assembly, a discharging assembly, a motor assembly, a universal shaft assembly, a mechanical pushing vertical drill assembly, a hydraulic impact device and a transmission assembly in the drilling tool combination structure are in threaded connection from top to bottom. The releasing disc, the releasing connecting rod, the motor rotor and the universal shaft upper ball hinge joint are sequentially connected in a threaded mode. The universal shaft lower ball joint, the transition transmission center shaft and the lower joint are connected through threads from top to bottom. The screw drill, rotary drilling, vertical drilling and logging while drilling are integrated, the production cost is reduced, and the drilling efficiency is improved.

Description

technical field [0001] The invention relates to a petroleum drilling tool, in particular to a screw drilling tool assembly, in particular to an impact screw drilling tool assembly with functions of information storage and vertical drilling, and belongs to the technical field of drilling machinery. Background technique [0002] With the continuous development of oil and natural gas exploration and development technology, the current status of oil and gas development in the world has shifted from the original main mining blocks to blocks with complex formation conditions and poor oil and gas storage properties. Especially in areas with high and steep piedmont structures and large formation dips, due to the strong natural deflection ability and the difficulty of deflection prevention and straight drilling, well deviation is prone to occur during drilling, which directly affects the quality of the wellbore and the drilling speed. [0003] For the above-mentioned vertical drillin...
