摘要
Abstract
In China,it has been established in core capabilities for deep-sea drilling technology,including remote wireline coring,automatic control,safety protection and efficient deployment,formed a relatively complete equipment system and accumulated rich practical experience in oceanic scientific expeditions.With the expansion of deep-sea scientific exploration into deeper waters,higher requirements have been put forward for the automation level,operational efficiency and safety reliability of drilling equipment.In order to meet future drilling needs under complex deep-sea geological conditions and solve the shortcomings of existing power heads in emergency escape and coring operation efficiency,this paper designs a new type of power head for deep-sea wireline coring drill.It has been focused on optimizing the transmission and integration scheme in power head structural design:an abandoning and impact release mechanism has been integrated within reduction gearbox to enhance the emergency handling and escape capabilities of drilling rig under complex working conditions such as stuck pipe;at the time,the wireline coring winch device is integrated into powerhead body,realizing integrated coring operation,effectively shortening auxiliary coring time and improving core sample collection efficiency.Application shows that this new power head has significant advantages in improving equipment emergency response capabilities and coring efficiency,and can provide technical support for the automation and integration development of deep-sea drilling equipment in the future.关键词
