Abstract

The invention discloses an automatic rotary steerable drilling tool for petroleum, which comprises a rotary head, a drill bit, a piston cylinder, an edge block, a rotary drill string, a control valve, a water inlet pipe, a water return hose, a connecting pipeline, a spray head and a spray hole. One end of the rotary head is provided with a drill bit, and the other end of the rotary head is fixedly connected with one end of the rotary drill string. A control valve is provided inside the rotary drill string. One end of the surrounding return hose is connected, the other end of the return hose is connected with one end of the connecting pipeline inside the rotary head, and the other end of the connecting pipeline is connected with the nozzle inside the drill bit. This device is used in existing oil drilling Adding a water spray device to the tool can not only cool the inside of the drill bit, but also spray through the nozzle to spray the drilling site, soften the soil at the drilling site, and increase work efficiency.

Description

technical field [0001] The invention relates to a petroleum drilling tool, in particular to a petroleum automatic rotary steerable drilling tool, which belongs to the technical field of petroleum machinery. Background technique [0002] The oil drill bit is an important tool for oil drilling, and its working performance will directly affect the drilling quality, drilling efficiency and drilling cost. The design of oil drill bits is mostly based on practical experience, combined with trial and error methods, repeated design and calculation, so the design accuracy is low, the cycle is long, it is difficult to improve the design quality, and only one drill bit can be designed for each calculation, and the efficiency is low. Therefore, it is very necessary to develop a set of oil drill bit CAD system to realize the parametric drawing of oil drill bit. 1 Overall design of the system The oil drill bit parametric drawing system adopts the programming method of functional modulariz...
