Beschreibung
Zusammenfassung:	The utility model discloses a hydraulic drive system of ocean well drilling compensation winch utilizes hydraulic pressure secondary regulation component and passive pneumatic cylinder combined drive winch to accomplish the heave compensation function, utilizes and send brill hydraulic motor drive winch to accomplish the automatic bit feeding function. In the compensation process, utilize passive pneumatic cylinder and liquid gas energy storage equipment to undertake whole dead loads of rig to it retrieves and releases to carry out periodicity to load gravitional force, all the other load in the compensation process are overcome in the constant voltage network to the work of hydraulic pressure secondary regulation component to utilize liquid gas energy storage equipment to carry out periodicity recovery and release to winch rotary system's inertia kinetic energy. In sending the brill motion process, utilize and send brill hydraulic motor and liquid gas energy storage equipment to retrieve rig load gravitional
