A lever-type steerable drilling tool and drilling device

Abstract

The invention discloses a lever-type steering drilling tool and a drilling device. The lever-type steering drilling tool includes a rotor (1) and an outer sleeve (2). The upper end of the outer sleeve (2) is provided with a plurality of first Hydraulic push pedal unit, the lower end of the outer sleeve (2) is provided with a plurality of second hydraulic push pedal units, the first hydraulic push pedal unit contains a first push pedal (5) and a first hydraulic module (4), the second A hydraulic module (4) can push the first push plate (5) out of the outer peripheral surface of the outer sleeve (2), and the second hydraulic push plate unit has a second push plate (9) and a second hydraulic module (10) , the second hydraulic module (10) can push the second push plate (9) to protrude from the outer peripheral surface of the outer sleeve (2). The lever-type steering drilling tool contains two sets of upper and lower push plates, which can greatly improve the deflection capability of the steering tool, and the use of the upper and lower sets of push plates also makes the tool more stable.

Description

technical field [0001] The invention relates to the field of drilling equipment, in particular to a lever-type steering drilling tool and a drilling device. Background technique [0002] With the rapid development of my country's national economy, the country's demand for oil and gas resources is increasing year by year. The intensity of oil and gas exploration continues to increase, and the difficulty of mining is increasing. In many oilfields, the reservoir thickness is small and the formation structure is complex. It is difficult for vertical wells to meet the current production requirements. Horizontal wells can greatly improve production efficiency. However, the drilling technology of horizontal wells is relatively complicated. Major oil companies in the world are researching rotary steerable tools used in horizontal wells, and the push-back rotary steerable tool is a steering tool that is widely used and has strong applicability. However, the push-to-type rotary stee...
