Product features
1. High-pressure nitrogen directional drilling rig is a general term for directional drilling rig and nitrogen-making device;
2. High nitrogen DDR technique is an underbalanced drilling one using high nitrogen as the circulating medium.Compared with ordinary drilling technique,it has the advantages of high mechanical speedand good safety;
3. High nitrogen drilling can be realized at a high mechanical speed,which is generally 3∽8 times of that of conventional hydraulic drilling mode;
4. Using high nitrogen drilling technique can easily pass through abnormal formations;
5. Since there is no liquid phase in gas drilling,it will not involve the problem of hydration instability in shaft lining.High nitrogen drilling is highly safe;
6. Under normal supporting and monitoring means,harmful gas pollution and natural gas deflagration will not occur.
Application
1.It is suitable for complex drilling with high gauss;
2.It is used to reduce the gas and oxygen concentration to prevent spontaneous combustion and fire;
3.Installation Location: Underground
4.Ambient Temperature: 0-40℃
