Abstract

The invention relates to a steel wire rope pushing device for drilling tool fishing. The steel wire rope pushing device is mainly applied to drilling tool fishing in casing drilling. According to the technical scheme, an upper connector is installed at the upper end of a mandrel, and a sliding sleeve is installed at the lower end of the mandrel; one end of an upper connecting rod is hinged to the upper connector, and the other end of the upper connecting rod is hinged to a connecting block; one end of a lower connecting rod is hinged to the sliding sleeve, and the other end of the lower connecting rod is hinged to the connecting block; and an installation ring is arranged in the middle of the mandrel, a flow blocking device is arranged between the installation ring and the connecting block, and the installation ring and the sliding sleeve are connected through extension springs. According to the steel wire rope pushing device, the traction force can be adjusted by adjusting the flow speed of a medium in a casing, and the steel wire rope pushing device can be applied to casing drilling of horizontal wells and extended-reach wells.

Description

technical field [0001] The invention relates to a steel wire rope pushing device for drilling tool salvage, which is specifically applied to oil and gas well steel wire rope operations, especially drilling tool fishing operations in casing drilling. Background technique [0002] The casing drilling system refers to a drilling system that uses ordinary casing as the drill string. The casing not only transmits mechanical energy (torque) but also transmits liquid energy to the drill bit. It can run casing while drilling, saving a lot of well construction costs. It has the advantages of reducing tripping times, shortening tripping time, saving costs, and reducing downhole accidents. [0003] At present, retrievable casing drilling tools are the most widely used, and this process uses wire rope to salvage the lower part of the casing. Wire rope hoisting has the advantages of high efficiency and rapidity, and is widely used in workover, salvage, logging and other operations. In...
