海洋钻井绞车补偿系统技术分析

介绍了海洋钻井绞车补偿系统特点、补偿原理、动力配备、电机选型等。该绞车除具备常规的提升下放功能外,还具有主动补偿功能,可解决浮式海洋平台升沉对钻井作业的影响;该方案可替代其他类型的专用升沉补偿装置,具有传动简单、钻井效率高等优点,可减轻整个平台的质量,减少占用空间,减小投资成本。海洋钻井补偿绞车集绞车和补偿装置功能于一身,可广泛应用于浮式钻井平台。

Technical Analysis on Offshore Drilling Drawworks Heave Compensation System

The paper mainly presents the theme on offshore drawworks（DW） heave compensation system through the following aspects：system characteristic, working principle, power consume, motor selection, etc. The drawworks has the function of active heave compensation except the normal hoisting function and can eliminate the impact on drilling work when the floating platform move Up and down. This DW can instead of the other heave compensation equipments. There are many predominances on the DW heave compensation system, such as simple driven device, out-standing efficiency,the small cubage, the less weight, the low cost, and so on. The function of drilling drawworks and heave compensation equipment are integrated to one unit,hence the offshore drilling drawworks can be widely used in the floating drilling platform.
