Wellhead pressurized snubbing device

Wellhead pressurized snubbing device
Product Detailed
1.For tripping operation of petroleum string under pressure in oilfield workover operation 2.Advanced technology 3.Efficient

Introduction:

DY18-21/35 wellhead pressurized snubbing device is a special-purpose equipment for tripping operation of petroleum string under pressure in oilfield workover operation. This device can achieve safe, reliable snubbing in and out of the string from the well without well killing or blowout, which can reduce the water injection frequency and save sewage treatment costs. This equipment can avoid the reduction of the surrounding oil well production because of reduction of regional ground pressure caused by blowout, and reduce environment pollution, protecting the oil and gas resources at maximum limit. Generally, DY18-21/35 wellhead pressurized snubbing device is a new type, highly efficient and stable pressurized workover equipment. This device adopts individual type structure design, and the power system can use the power system of the workover rig or specialized assorted power station system.

Features:

1. Advanced technology.

2. Convenient operation and good reliability.

3. High operating efficiency.

4. Energy-saving and environment friendly.

5. Good comprehensive properties.
