Abstract:

Heave compensation system is the key equipment of the floating drilling platforms and the drill string which has the
appropriate compensation for doing heave motion at times of waves and other natural loading,in the process of developing deepsea
oil drilling. The device can effectively reduce a series of impact that oscillating up and down movement has on drilling,
ensuring the stability and safety of the overall process of drilling system and the stability of the downhole drilling pressure.
Through the extensive literature survey,analysis of the situation of the development and application of heave compensation
system in our country was made. Combined with application and research status of the heave compensation device in our
country,and by using the theory of multiple floating body and drilling dynamics characteristics,we put forward new ideas
on further in-depth study and the technology roadmap of the device,to promote China′s offshore oil equipment independent
research and development.
