Technical Field
The invention relates to the technical field of oil rigs, in particular to a derrick device for a four-single-upright-column drilling machine.
Background
With the continuous exploitation of petroleum resources, the petroleum resources of medium and shallow strata are increasingly reduced, so that the exploitation of deep and ultra-deep oil and gas resources will become a main way for acquiring petroleum resources in the future.
The traditional 8000m and 9000m deep well and ultra-deep well drilling machines all drill by using three single upright post units, and because the drilled stratum is deep, the drilling is frequently started and stopped, the drilling period is also prolonged, and the mining cost is greatly increased compared with the mining of middle and shallow layer petroleum resources.
In order to further improve the tripping speed, shorten the drilling period and reduce the drilling cost, four single columns are combined into a tripping unit, and the tripping unit is longer than a conventional three-single column by one single column by about 9.4 m.
However, since a single column is added, the column is lengthened, the flexibility of the column is obviously increased, and the risks of large deformation, instability, slippage, even overturning and the like of the column during the processes of leaning, placing and transporting the column may occur.
In addition, due to the fact that a single head is added, the effective height of the derrick is increased by about 8m compared with that of a derrick of a traditional 9000m ultra-deep well drilling machine, the height of the derrick is increased, and the main problem is that the overall mass of the derrick is increased, so that the lifting load of the derrick is increased, and the lifting stability is reduced.

Referring to fig. 6, the propeller strut 3 is lifted by a propeller strut lifting cylinder 12 mounted on the base 1.
The top end of the propeller strut 3 is also provided with a guide pulley.
The working principle and the using process of the invention are as follows:
the derrick, the propeller strut and the base are integrally assembled on the ground at a low position.
After the low-position installation of the propeller strut 3 is completed, a set of propeller strut lifting hydraulic cylinders are arranged on the rear legs 302 of the propeller strut 3, a hydraulic source is provided by a drilling machine tool hydraulic station, the propeller strut 3 is lifted in place by the hydraulic cylinders, and the installation and the lifting are more convenient and safer. The lifting principle of the propeller strut is schematically shown in figure 6.
And after the propeller strut 3 is lifted in place, the well lifting frame 4 is lifted. The bottom support foot of derrick 4 is arranged on the preceding base 101 of base 1, and the load of derrick 4 can directly transmit to base 1 and basal plane on for base 1 whole stress situation is better, has increased the overall stability of rig. The derrick 4 is lifted from the horizontal position to the vertical position by means of the power of the winch 7 on the rear base 103 of the base 1 and the lifting rope pulled by the fast rope, the hook, the lifting tripod and the like. The hoisting process of the derrick 4 is a principle of the prior art, so the scheme is not detailed.
When the derrick 4 is lifted, in order to enable the derrick 4 to be stably placed on the propeller strut 3 and enable the gravity center of the derrick 4 to move forwards when the derrick 4 is lowered, the derrick 4 falls by the self weight of the derrick 4, a hydraulic buffer device 303 (a hydraulic cylinder) is arranged on the propeller strut 3, and the control of the derrick 4 is realized by the expansion and contraction of the hydraulic buffer device 303. After the derrick 4 is slowly lifted to be in contact with the fully extended hydraulic buffer 303, the hydraulic buffer 303 is appropriately retracted, and after the derrick 4 is lifted to the proper position, a locking device (in the prior art) between the lower body of the derrick 4 and the propeller strut 3 is locked.
