Substructure for ZJ90DB Double lifting drilling rig
Substructure for ZJ90DB Double lifting drilling rig
In view of the problems such as insufficient clear height and poor lifting safety of ultra-deep oil and gas drilling rig substructure in China, we have developed the 7000-9000m double-lifting drilling rig to lead the development of ultra-deep drilling rig in China.
High clear height: Double-lifting type, rig floor height is 13.7m,the clear height is 12m.
Lightweight mast raising up: Lifting load is less than 1800KN.
Raising up Substructure remotely, hydraulic drawworks remote raising up with high safety.
Strong adaptability: The drawworks is installed on the rig floor, which isconducive to cluster well operation and transfer of large modules between well sites.
High stability: The offset of drilling rig wellhead center is just 50% of similar type normal drilling rig under the heavy load.
Innovative pipe operation process, tripping speed is up to 25 strings/h，improving pipe string handling efficiency by more than 20%.
One-key operation system realizes the pipe string processed operation.
Automatic coordinate alignment removes the effect of interferences.
Laser real-time detection for connecting between manipulator and drill string to avoid collision accidents.
Selection Notes for Substructure for ZJ90DB Double
Substructure for ZJ90DB Double should be reviewed against the actual operating duty and supporting equipment, not only the model name. Confirm rated depth or hook load, mast and substructure arrangement, mobility, power source and wellsite access before quotation.
