The invention discloses a lever type steering drilling tool and a drilling device. The lever type steering drilling tool comprises a rotor (1) and an outer sleeve (2), a plurality of first hydraulic push plate units are arranged in the upper end of the outer sleeve (2), a plurality of second hydraulic push plate units are arranged in the lower end of the outer sleeve (2), the first hydraulic pushplate units comprise first push plates (5) and first hydraulic modules (4), the first hydraulic modules (4) can push the first push plates (5) to stretch out of the peripheral face of the outer sleeve(2), the second hydraulic push plate units comprise second push plates (9) and second hydraulic modules (10), and the second hydraulic modules (10) can push the second push platse (9) to extend out of the peripheral surface of the outer sleeve (2). The lever type steering drilling tool comprises the upper push plates and the lower push plates, the deflecting capacity of a steering tool can be greatly improved, and the stability of the lever type steering drilling tool is higher through the use of the upper push plates and the lower push plates.
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...
