Technical field
This utility model belongs to drilling equipment technical field, is related to a kind of ocean exploration ship hydraulic lifting door type derrick drilling well System.
Background technology
During marine geologic survey, Exploration of Oil And Gas and subsea production system installation and operation, using installation Rig on ocean exploration ship, carries out comprehensively fine to the seafloor topography in local marine site, geologic feature, hydrologic parameter etc. Detection investigation.However, existing small-sized investigation vessel, the equipment volume installed thereon is big, weight weight, takes up room many, integrated Change degree is not high, have impact on work efficiency.
Utility model content
The purpose of this utility model is to provide a kind of ocean exploration ship hydraulic lifting door type derrick well system, solves existing Have that the ocean exploration ship rig of technology is unreasonable in structure setting, the volume that takes up room is big, weight weight, integration degree be not high Problem.
This utility model be employed technical scheme comprise that, a kind of ocean exploration ship hydraulic lifting door type derrick well system, In the postmedian of ocean exploration ship, derrick is installed, in derrick inside casing along being provided with slide rail, is provided with top in slide rail and drives, in derrick The every side in top is mounted on two fixed pulleys, is separately installed with one group of basal disc stretcher outside upper derrick two;After derrick Facade is hinged with elevating ram, and elevating ram cylinder body lower end is hinged with the ear mount on deck;The deck of derrick both sides is installed There is basal disc winch;
The basal disc steel wire rope that basal disc winch from every side is drawn bypasses the basal disc stretcher of this side and two fixed pulleys successively It is connected with the seabed basal disc in investigation vessel moon pool afterwards;After the boom hoist cable that dead line anchor is drawn bypasses the guide wheel of this side successively with Top is driven and is connected.
Ocean exploration ship hydraulic lifting door type derrick well system of the present utility model, is further characterized in that:
Dead line anchor, dynamic catwalk and grab pipe machine are respectively arranged with the deck in front of derrick, the bottom of derrick both sides is respectively Liquid gas tong is installed, derrick is provided with video monitor.
Derrick is supporting to be provided with driller house, and the controlling organization in driller house is connected with the control of each action component.
The beneficial effects of the utility model are, including the following aspects:
1) elevating ram of door type derrick configuration instead of the supporting well drilling hoist of conventional derrick and overhead traveling crane, using hydraulic oil Cylinder and sliding system match and drive top to drive up and down motion, realize the put-on and delegated function of drill string;Door type derrick and routine simultaneously It is obvious that derrick compares weight reduction effect.
2) supporting hydraulic power supply provides power for the equipment such as most of drilling equipment and passive compensation system, thus dropping Low number of devices, reduces the overall dimensions of equipment.
3) door type derrick structure is simple, is more suitable for the well-sampling operation of shallow water area, disclosure satisfy that surveying of 500 meters of depth of waters Examine and sampling demand it is not necessary to supporting conventional derrick need overhead traveling crane, the equipment such as winch.Meanwhile, the lift cylinder of door type derrick There is lifting/decentralization, passive compensation function, without passive compensator being separately configured it is only necessary to configure Hydraulic Station, thus reducing Number of devices, reduces the overall dimensions of equipment, and whole system is few for quantity, and electrical equipment quantity is low, safeguards and use cost It is greatly lowered, improve working performance.
