Abstract

The invention discloses an integrated double-roller drilling winch with a compensation function. The integrated double-roller drilling winch comprises a transmission part and a control part. Accordingto the structure of the transmission part, the transmission part comprises a winch base, and the winch base is used as an installation foundation; a pair of left roller bearing seats and a pair of right roller bearing seats are coaxially installed on the winch base in the longitudinal direction, and the pair of left roller bearing seats is provided with left rollers; the left rollers are in transmission connection with left roller reducer casings through a left roller main spindle coupling device, and the left roller reducer casings are in corresponding transmission connection with left roller variable frequency motor units through two left roller motor coupling devices; the pair of right roller bearing seats is provided with right rollers, and the right rollers are in transmission connection with right roller reducer casings through a right roller main spindle coupling device; and the right roller reducer casings are in corresponding transmission connection with right roller variablefrequency motor units through two right roller motor coupling devices. The integrated double-roller drilling winch is compact in structure, flexible in using and reliable in working.

Description

technical field [0001] The invention belongs to the technical field of offshore oil drilling equipment, and relates to an integrated double-drum drilling drawworks with compensation function. Background technique [0002] Offshore floating drilling equipment is one of the main equipment for oil and gas exploration and development in ocean deep water and ultra-deep water. The normal operation of the device is greatly affected. In order to ensure the normal operation of the drilling operation, the drilling device of the offshore floating drilling equipment must be equipped with a heave compensation mechanism to counteract the heave movement of the platform. The quality of the heave compensation mechanism has also become a measure of marine A key indicator of floating drilling rig performance. [0003] Currently widely used heave compensation mechanisms include crown block compensation mechanism, traveling block compensation mechanism, drawworks compensation mechanism, dead ro...
