Abstract
The invention relates to a double traveling lifting system of a well drilling and repairing machine, which is characterized by comprising a main lifting system for descending/lifting a pipe column and an auxiliary lifting system for taking/throwing a three-joint unit, wherein the main lifting system comprises a main winch arranged on a drill floor, a main pulley block arranged on an overhead traveling crane and a runner wagon, and the main winch bypasses the main pulley block through a cable so as to suspend the main runner wagon; and the auxiliary lifting system comprises an auxiliary winch arranged on the drill floor, an auxiliary pulley block arranged on the overhead traveling crane and an auxiliary runner wagon, and the auxiliary winch bypasses the auxiliary pulley block through the cable so as to suspend the auxiliary runner wagon. By adopting the double lifting system, the well drilling and repairing machine can complete the operation of descending/lifting the pipe column and taking/throwing the three-joint unit at the same time, so the working efficiency of the well drilling and repairing machine is greatly improved.
Description
Technical field
The present invention relates to a kind of Hoisting System of drilling and workover machines, particularly about a kind of can descending simultaneously/lift pipe string with connect/get rid of two Hoisting System of moving about of the drilling and workover machines of thribble (with two or three endowels is the unit of unloading, and is called thribble).
Background technology
As shown in Figure 1, existing oil drilling and workover machines has only a derrick and a cover Hoisting System, therefore when carrying out the drilling and repairing well operation, can only finish the work that connects/get rid of thribble or following/lift pipe string at well head, be the oil drilling and workover machines connect/when getting rid of thribble, then can't finish down/lift pipe string, thereby cause the operating efficiency of oil drilling and workover machines lower.This traditional drilling and repairing well operating type is widely used on land and offshore drill workover rig.But because offshore drill workover treatment expense is very high, we wish to improve the operating efficiency of offshore drill workover rig, to reduce the cost and the expense of drilling and repairing well operation.Therefore, in order to improve the operating efficiency of offshore drill workover rig, press for a kind of traditional operating type difference, operating efficiency is realized above-mentioned job requirement than higher oil drilling and workover machines.
Summary of the invention
At the problems referred to above, the purpose of this invention is to provide two Hoisting System of moving about of a kind of can descending simultaneously/lift pipe string and the drilling and workover machines that connects/get rid of thribble.
For achieving the above object, the present invention takes following technical scheme: a kind of two Hoisting System of moving about of drilling and workover machines is characterized in that: and it comprises and one being used for down/and the main Hoisting System and of lift pipe string is used to connect/get rid of the service hoisting system of thribble; Described main Hoisting System comprises that one is arranged on main winch one on the rig floor and is arranged on a head pulley group and a main tourist bus on the overhead traveling crane, and described main winch hangs main tourist bus after walking around described head pulley group by hawser; Described service hoisting system comprises that one is arranged on auxiliary winch, on the described rig floor and is arranged on an auxiliary pulley group and an auxiliary tourist bus on the described overhead traveling crane, and described auxiliary winch hangs described auxiliary tourist bus after walking around described auxiliary pulley group by hawser.
Described head pulley group and auxiliary pulley group all are arranged on the main shaft of described overhead traveling crane, and the spacing of described head pulley group and auxiliary pulley group is greater than 0.5m.
Described main Hoisting System and service hoisting system all control at main driller station, and described service hoisting system also is provided with independently console and controls.
The present invention is owing to take above technical scheme, and it has the following advantages: 1, the present invention is owing to adopt dual lift system, make drilling and workover machines can finish down simultaneously/lift pipe string with connect/get rid of the operation of thribble, thereby greatly improved the operating efficiency of drilling and workover machines.2, head pulley group of the present invention and auxiliary pulley group all are arranged on the main shaft of overhead traveling crane, more can save the derrick space than two overhead traveling cranes of direct employing.3, used main winch and auxiliary winch to work simultaneously among the present invention, thereby increased work efficiency.4, the workover rig Hoisting System among the present invention also is suitable in than the drillng operation of shallow well and is higher than the operating efficiency of common small-sized drill.5, application of the present invention is strong, is not only applicable to special offshore drill workover rig, also can be generalized in the drilling and workover machines on land.

The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in detail.
As shown in Figure 2, the present invention includes one be used for down/the main Hoisting System 1 and of lift pipe string is used to connect/get rid of the service hoisting system 1 of thribble, wherein main Hoisting System 1 comprises that one is arranged on main winch 11, on the rig floor 3 and is arranged on a head pulley group 12 and a main tourist bus 13 on the overhead traveling crane 4, and main winch 11 is walked around head pulley group 12 backs by hawser and hung main tourist bus 13.Service hoisting system 2 comprises that one is arranged on auxiliary winch 21, on the rig floor 3 and is arranged on an auxiliary pulley group 22 and an auxiliary tourist bus 23 on the overhead traveling crane 4, and auxiliary winch 21 is walked around auxiliary pulley group 22 backs by hawser and hung auxiliary tourist bus 23.
In the foregoing description, head pulley group 12 and auxiliary pulley group 22 all are arranged on the main shaft 41 of overhead traveling crane 4, and the spacing of head pulley group 12 and auxiliary pulley group 22 is collided (as shown in Figure 3) to prevent main tourist bus 13 and auxiliary tourist bus 23 greater than 0.5m.
In the foregoing description, main Hoisting System 1 and service hoisting system 2 all can control at main driller station, and service hoisting system 2 also is provided with independently console and controls.
Workover rig operating type of the present invention also can be used for drilling well simultaneously, also can make up a joint during drilling well and following brill carries out simultaneously, perhaps pulls out of hole and breaking down carries out simultaneously, and is the same with the operation procedure of well workover.
The present invention only describes with the foregoing description; the structure of each parts, the position is set and connects and all can change to some extent; on the basis of technical solution of the present invention; all improvement and equivalents of individual component being carried out according to the principle of the invention all should not got rid of outside protection scope of the present invention.
