Petroleum drilling and production machine convenient to disassemble and assemble

Abstract

The invention discloses a petroleum drilling and production machine convenient to disassemble and assemble. The petroleum drilling and production machine structurally comprises a tail section, middlesections, an end section and a drill bit, wherein the middle sections are connected with the tail section and the end section in an assembly mode, the end section is connected to the drill bit, each middle section is composed of a belleville spring structure and a piston device, the belleville spring structures are connected to the piston devices in an assembly mode, the end section is provided with a valve position, the drill bit includes a resilient structure and a drill bit body, the resilient structure is connected to the drill bit body, each belleville spring structure includes a belleville spring plate and a transmission belleville spring, the belleville spring plates are adjacent to the transmission belleville springs, the belleville spring structures are provided with belleville spring assembling joints, and each piston device comprises a piston plate, a transmission piston and a piston tail plate. According to the machine, a sensing board carries out real-time ranging to control the transmission of the resilient structure, so that the resistance of the drill bit during propulsion is not increased, the rotating speed is stable, the abrasion of the drill bit during running is reduced, the belleville spring structures and the piston devices are reinforced through spring correcting devices and the piston tail plates, transmission dislocation and spring twisting are avoided, and the overall pushing effect of the tool is good.

Description

technical field [0001] The invention relates to the field of petrochemical general machinery, in particular to a petroleum drilling and production machinery which is easy to assemble and disassemble. Background technique [0002] The hydraulic oscillator is a drilling tool that realizes drilling by generating axial vibration, and can drill for a long time and a long distance. Deviated wells in oil drilling have good economic benefits, but the inclination continues to increase, and spud drilling The difficulty also increases. [0003] In the existing technology, if the drilling inclination is too large, the resistance of the drill bit will increase when it is propelled, not only the speed will decrease but also the wear will increase. weakened. Contents of the invention [0004] The main purpose of the present invention is to overcome the deficiencies of the prior art, to provide a kind of oil drilling and production machinery that is easy to disassemble, to solve the pro...

Problems solved by technology

[0004] The main purpose of the present invention is to overcome the deficiencies of the prior art, to provide a kind of oil drilling and production machinery that is easy to disassemble, to solve the problem that the drilling deviation is too large, the resistance of the drill bit increases when it is propelled, not only the speed decreases but also the wear increases, and the drilling tool The internal pushing structure will also be affected by the inclination, causing transmission misalignment and spring distortion, and the overall driving force of the tool is weakened.
