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.
