Problems solved by technology

[0003] Although the air control is widely used, there are still some defects. For example, in the low temperature environment, the air control components are easy to be frozen, which slows down the transmission speed of the air control and reduces the efficiency of the drilling rig.

Embodiment 1

[0020] Such as figure 1 and figure 2 As shown, the present invention first antifreezes the gas path of the oil drilling rig through the antifreeze mechanism in a low temperature environment. The cabinet of the antifreeze mechanism can be arranged outdoors together with the rig. It is sent to the fan, and the compressed air becomes pure and dry after being finely filtered by the water separator. The filtered air is sent to the heating chamber to be heated by the heating pipe, and then enters the external drilling rig air circuit through the air outlet pipe. , the air control components can be reheated, so that each air control component can maintain a temperature above 0°C in a low temperature environment without freezing and freezing; wherein the antifreeze mechanism includes a cabinet 1, an air compressor 2, a fan 4, a heating Chamber 7, air inlet pipe 3 and air outlet pipe 8, air compressor 2, fan 4 and heating chamber 7 are all arranged in cabinet 1, fan 4 is connected w...

Abstract

The invention discloses an antifreeze method for the gas circuit. Firstly, the gas circuit of the oil drilling rig is antifreeze treated by an antifreeze mechanism in a low temperature environment. The cabinet of the antifreeze mechanism can be installed outdoors together with the rig. After the pipe enters, the air compressor sends it to the fan. The compressed air becomes pure and dry after being finely filtered by the water separator. The filtered air is sent to the heating chamber to be heated by the heating pipe and then enters through the outlet pipe In the air circuit of the external drilling rig, the air control components can be reheated, so that the air control components can maintain a temperature above 0°C in a low temperature environment without freezing and freezing.

Description

technical field [0001] The invention relates to an antifreeze mechanism, in particular to an antifreeze method for an air circuit. Background technique [0002] In oil drilling, the drilling tool is driven to break the rock, drill into the ground, and drill a wellbore with a specified depth for the oil or gas extraction machine to obtain oil or natural gas. a regular oil drilling rig Generally, there are eight major systems: including hoisting system, rotating system, drilling fluid circulation system, transmission system, control system, power drive system, drilling rig base, drilling rig auxiliary equipment system, capable of tripping, rotating drilling, circulating well washing ability. Modern oil drilling rigs are linkage units of multiple working machines, requiring various mechanisms and systems to be organically combined into a unified whole, and to work accurately, coordinately and efficiently, a sensitive, accurate, safe and reliable control system is necessary. ...
