Winter rubber core passing auxiliary heating device for double-rubber-core rotating head

Abstract

The invention relates to the technical field of a rubber core heating device for a double-rubber-core rotating head, in particular to a winter rubber core passing auxiliary heating device for the double-rubber-core rotating head. The winter rubber core passing auxiliary heating device comprises an upper rubber core heating outer capsule sleeve, an upper rubber core heating inner capsule, a lower rubber core heating outer capsule sleeve, a lower rubber core heating inner capsule and a communicating tube capsule; the upper rubber core heating outer capsule sleeve and the lower rubber core heating outer capsule sleeve are mounted together in a communicating manner through the communicating tube capsule; the upper rubber core heating inner capsule and the lower rubber core heating inner capsule are sequentially mounted on the communicating tube capsule at intervals from top to bottom. The winter rubber core passing auxiliary heating device has the advantages that the structure is reasonable and compact, and the application is convenient; the upper rubber core can be heated through the upper rubber core heating outer capsule sleeve and the upper rubber core heating inner capsule, in which hot vapor is injected, the lower rubber core can be heated through the lower rubber core heating outer capsule sleeve and the lower rubber core heating inner capsule, in which hot vapor is injected, when the upper rubber core and the lower rubber core are heated to restore elasticity, a drill tool is enabled to safely and rapidly pass through the double-rubber-core rotating head in cold winter, the operating time of the drill tool on entering a well is shortened, and the operation is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of a rubber core heating device for a double rubber core rotary head, and is an auxiliary heating device for a double rubber core rotary head to wear rubber cores in winter. Background technique [0002] When implementing underbalanced drilling in winter, the drilling tool needs to be lowered into the well through the double rubber core rotary head. Due to the influence of the external temperature, the elasticity of the rubber core inside the rotary head is reduced, and it is difficult for the drilling tool to pass through the rubber core inside the rotary head. Extend the operation time of the drilling tool into the well; at the same time, the drilling tool is easily bent and deformed due to excessive force; and the deformed drilling tool will cause the rotary head to swing radially above the drilling platform when it goes down, which is easy to damage the surrounding equipment or operating personnel, there...
