Low temperature drilling system

Abstract

The invention relates to a low temperature drilling system, comprising a rail structure and a drilling platform disposed on the rail structure. The drilling platform is provided with a low temperaturedrilling machine, and the drilling platform is provided with an oil discharging pipeline system, and the oil discharging pipeline system comprises a communication with the oil well inner cavity. Theoil suction pipe has one oil outlet pipe on one side of the oil suction pipe, and a plurality of transition sleeves are arranged on the oil suction pipe, the two ends of the transition sleeve are connected with the oil suction pipe, and the transition sleeve and the oil discharge pipe are connected through the transition pipe, and the oil pipe is connected Connecting a plurality of oil-extractingbranch pipes, the oil-distributing branch pipe is connected to the oil storage tank, one side of the oil storage tank is connected to the oil-distributing branching mechanism; the oil-distributing branching mechanism comprises an oil discharging box, and one side of the oil discharging box is provided with an oil connecting pipe connected with the oil storage tank, and the oil discharging pipe isconnected An oil guiding tube is arranged on the other side faces of the oil tank, and a stirring shaft is arranged in the oil discharging box, a flange is fixed on the surface of the oil dischargingbox, and a rotating electric machine outside the flange is connected with the stirring shaft to ensure oil in each oil discharging branch pipe. The amount is basically the same and the stability is high.

Description

technical field [0001] The invention relates to an oil drilling device, in particular to a low temperature drilling system. Background technique [0002] Existing cryogenic drilling systems include drilling platforms, solids control systems, and drill pipe storage devices. In actual use, most of them are one-line structures and all use wheeled movement. However, the design of wheeled movement often requires the use of oil cylinders to integrate the cryogenic drilling system Lifting, otherwise the equipment cannot be fixed. In addition, after the oil cylinder system is used to lift, additional leveling is required, which greatly increases the installation time of the equipment during use, and the cryogenic drilling system has oil output too quickly As well as the problem of inconvenient regulation of the oil output, the low-temperature drilling rig needs to lay tracks at the bottom during use to facilitate the translation of the low-temperature drilling rig. The current track...

[0002] Existing cryogenic drilling systems include drilling platforms, solids control systems, and drill pipe storage devices. In actual use, most of them are one-line structures and all use wheeled movement. However, the design of wheeled movement often requires the use of oil cylinders to integrate the cryogenic drilling system Lifting, otherwise the equipment cannot be fixed. In addition, after the oil cylinder system is used to lift, additional leveling is required, which greatly increases the installation time of the equipment during use, and the cryogenic drilling system has oil output too quickly As well as the problem of inconvenient regulation of the oil output, the low-temperature drilling rig needs to lay tracks at the bottom during use to facilitate the translation of the low-temperature drilling rig. The current track is generally a two-way track, and the low-temperature drilling rig uses its own driving machine to provide power to move on the track , the problem existing in the use of the current low-temperature drilling rig is that it is inconvenient to fix the low-temperature drilling rig on the track. question
