Abstract

The invention relates to a mechanical and hydraulic double-acting inclination guiding device anchoring tool used for fixing an inclination guiding device for oil gas well casing pipe interior openingwindow side drilling. The mechanical and hydraulic double-acting inclination guiding device anchoring tool solves the problem that during thick-wall casing pipe and double-layer casing pipe window opening side drill work, anchoring of the inclination guiding device is not reliable. According to the technical scheme of the mechanical and hydraulic double-acting inclination guiding device anchoringtool, the lower portion of a gear connector is provided with a gear retainer, a center gear is engaged with a planet gear, the planet gear is engaged with a sun gear, the sun gear is in threaded connection with an upper shell, the upper end of a middle connector is in threaded connection with the upper shell, the lower end of the middle connector is in threaded connection with a lower shell, and alower connector is connected with the lower shell through a shear pin; the upper end of an upper center shaft is in threaded connection with the center gear, the lower end of the upper center shaft and the upper end of a limiting shaft are in threaded connection, the upper end of a lower center shaft is in threaded connection with the lower end of the limiting shaft, and the lower end of the lower center shaft is in threaded connection with the lower connector. By means of the mechanical and hydraulic double-acting inclination guiding device anchoring tool, the inclination guiding device is anchored under the hydraulic and mechanical dual actions, the anchoring effect of the anchoring tool is improved, damage caused by cutting torque is improved, and the sliding risk of the inclination guiding device is reduced.

Description

technical field [0001] The invention relates to a mechanical-hydraulic double-action deflector anchoring tool used for fixing the deflector when sidetracking through windows in casing pipes of oil and gas wells. Background technique [0002] Casing window sidetracking technology is mainly used to restore production capacity of casing damaged wells, deformed wells and accident wells in old oilfield blocks, and it is also one of the important measures for low-cost development of remaining oil and gas reservoirs in mid-to-late stage oilfields. The core of casing window opening sidetracking technology is to have reliable and efficient window opening tools, and the hanging setting tool is one of the most important tools for casing window opening tools. At present, the deflector suspension tools used for window sidetracking in China mainly include three types: ground anchor type, mechanical type and hydraulic type. Among them, the ground anchor type suspension tool is reliable but...
