Double rubber core rotary head auxiliary heating device for wearing rubber core in winter

Abstract

The invention relates to the technical field of rubber core heating devices for double rubber core rotary heads, and is an auxiliary heating device for double rubber core rotary heads to wear rubber cores in winter; The core heating outer bag, the lower rubber core heating inner bag and the connecting pipe bag; the upper rubber core heating outer bag and the lower rubber core heating outer bag are connected and installed together through the connecting pipe bag; the connecting pipe bag is connected by An upper rubber core heating inner bag and a lower rubber core heating inner bag are installed at intervals from top to bottom. The invention has a reasonable and compact structure and is easy to use; the upper rubber core can be heated by heating the outer bag cover and the upper rubber core heating the inner bag by injecting hot steam, and the outer bag cover and the inner bag can be heated by injecting hot steam into the lower rubber core. The lower rubber core is heated by the inner bag to heat the lower rubber core. After the upper rubber core and the lower rubber core are heated and restored to elasticity, the drilling tool can pass through the double rubber core rotary head safely and quickly in the cold winter, shortening the drilling tool. The well operation time 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...
